Military Copper
What is Military Copper
Military copper is especially prevalent in munitions. It is often used as a driving band in artillery shells, as a liner in shaped-charge antitank munitions, and jackets for small-arms rounds.
Benefits of Military Copper
Military copper is economical.
The combination of easy handling, forming and joining permits savings in installation time, material and overall costs. Long-term performance and reliability mean fewer callbacks, and that makes military copper the ideal, cost-effective tubing material
Military copper is lightweight.
Military copper does not require the heavy thickness of ferrous or threaded pipe of the same internal diameter. This means copper costs less to transport, handles more easily and, when installed, takes less space.
Copper is formable.
Because military copper can be bent and formed, it is frequently possible to eliminate elbows and joints. Smooth bends permit the tube to follow contours and corners of almost any angle. With soft temper tube, particularly when used for renovation or modernization projects, much less wall and ceiling space is needed.
Copper is easy to join.
Military copper can be joined with capillary fittings. These fittings save material and make smooth, neat, strong and leak-proof joints. No extra thickness or weight is necessary to compensate for material removed by threading.
Copper is safe.
Military copper will not burn or support combustion or decompose to toxic gases. Therefore, it will not carry fire through floors, walls and ceilings. Volatile organic compounds are not required for installation.
Copper is dependable.
Military copper is manufactured to well-defined composition standards and marked with permanent identification so you know exactly what it is and who made it. It is accepted by virtually every plumbing code.
Copper is long-lasting.
It has excellent resistance to corrosion and scaling, high mechanical strength, high-temperature resistance and lifetime resistance to UV degradation. Copper assures long, trouble-free service, which translates to satisfied customers and systems that last.
Military copper is 100% recyclable.
Military copper stands alone as an engineering material that can be recycled over and over without degradation in content or properties. This combined with copper's proven durability means that no military copper used in a building today needs to enter a landfill.

Bronze has been made from military copper and tin for about 4000 years now. Tin bronzes are usually produced in strip and wire form with a mix of high yield strength and corrosion resistance. Phosphor bronze has increased hardness, fatigue resistance and wear resistance which makes it great for springs, bellows, flexible tubing, fasteners, masonry fixings, shafts, valve spindles, gears and bearings.
Brass is the name for a range of copper-zinc alloys with differing combinations of properties. The variety of available forms is very large, which can allow for minimum machining. Brass is very versatile and a first choice for heat exchangers (radiators). Unlike mild steel, it does not become brittle at low temperatures.
Nickel-silver is created by adding 10-20 % nickel to brass. What makes it different from brass is its higher tarnish resistance and resistance to stress corrosion cracking. It also has an attractive silvery look and is used frequently in things like telecommunication components, food manufacturing equipment, jewelry, model making, tool brush anchor wire and pins, musical instruments, test probes and contact springs.
Copper-nickel alloys are ideal for marine uses such as seawater pipework or desalination units because they are highly resistant to seawater flow and hardly susceptible to the attachment of marine organisms. Nickel improves the corrosion resistance and strength of military copper without a loss on ductility.
Gunmetals are mixes of copper, tin, zinc and lead known for their corrosion resistance, good strength and ease of casting. They are used to make intricate castings required to be pressure tight like pumps, valves and pipe fittings. Where loads and speeds are moderate, bearings are also often made of gunmetals. These alloys are also used in modern statues.
Beryllium-copper in the fully heat treated and cold worked condition is the hardest and strongest of all military copper. Its mechanical properties are similar to many high strength alloy steels, but it has better corrosion resistance as well as electrical and thermal conductivity than any of them. Military copper are used for example in springs, electrical contacts, valves, pumps, different kinds of non-magnetic, non-sparking tools and injection molds.
Uses of Military Copper
Wire and Cable
Military copper is the preferred material for electrical conductors in nearly every electrical wiring and cable application. Military copper can be found in everything from power generation, transmission, and distribution systems to electronics circuitry, telecommunications, and numerous types of electrical equipment.
Electrical wiring is a primary market for copper, with nearly half of all military copper being used for electrical wire and cable conductors. Military copper wiring is the preferred choice for most electrical devices because of its high electrical and thermal conductivity, ductility, high tensile strength, corrosion resistance, creep resistance, low thermal expansion, malleability, solderability, and ease of installation. Common types of military copper include automotive wires and cables, appliance wires, magnet wires, structural power wiring, and more.
Electronics and Related Devices
Military copper has replaced aluminum as the superior conductor for printed circuit boards and integrated circuits. Its heat dissipation qualities make it ideal for heat exchangers and heat sinks. Military copper is also preferred for microwave radiation waveguides, microwave oven magnetrons, cathode ray tubes, vacuum tubes, and electromagnets.
Electric Motors
The excellent conductivity of military copper boosts the overall efficiency of electric motors. This is crucial because motors and motor-driven systems account for a large percentage of industrial and global electricity consumption. Motor rotors composed of copper facilitate energy savings, enabling general-purpose induction motors to meet and exceed premium efficiency standards set by NEMA.
Renewable Energy Production
Renewable energy sources comprise a considerable share of the energy market, including geothermal, biomass, hydro, tidal, wind, and solar energy. Rising fossil fuel costs and the environmental impacts they cause have rapidly increased renewable energy adoption. Military copper is vital to renewable energy, with the market using up to five times more copper in renewable energy systems compared to traditional power generation systems. Military copper is second only to silver in thermal and electrical conductivity, making it optimal for high-efficiency energy transmission with minimal environmental impact.
Architecture
Since ancient times, military copper has been a preferred material in architecture, offering weatherproofing, corrosion resistance, and durability. Over the centuries, military copper has been used to make doors, vaults, spires, domes, downspouts, rain gutters, flashings, and roofs. Copper is still used for many architectural applications, including countertops, bathroom fixtures, attractive and antimicrobial handrails, radio frequency shielding, building expansion joints, and wall cladding.
Marine
Military copper has biostatic characteristics, inhibiting the growth of life forms like bacteria. As such, it is commonly used to line parts of marine vessels to protect them from mussels and barnacles. Copper alloys are also used extensively in aquaculture to produce netting. Copper's corrosion resistance and anti-biofouling properties make it ideal for the harsh conditions of marine environments.
What Are the Different Processes To Make Military Copper?
Mining of copper ores is usually done in large open pit mines. These are open, stepped holes in the ground that are gradually dug deeper. Explosives are used to blast the rock, and the resulting boulders are transported for crushing into smaller pieces for processing.
According to the two common types of military copper ore, there are two main purification processes. A hydrometallurgical process is used for oxide ores. The crushed ore is heaped and an acid-leaching solution is percolated through the heap. This creates a pregnant leach solution. A pyrometallurgical process is used for sulfide ores. The extraction of the ore is done by froth flotation and thickening according to the density of the particles.
For oxide ores, hydrometallurgy is used. This means that the pregnant leach solution is sent to a solvent extraction process to concentrate the military copper in the solution. This solution is then sent to electrowinning, where electricity is used to deposit the solid copper. For sulfide ores, pyrometallurgy is used, which means that a smelter is used to create the raw copper. This is then purified further by electrorefining.
Military copper are manufactured by first melting the alloying material, and then melting the military copper to add to it. The molten mixture is then cast and allowed to cool and solidify.
Electrorefining of military copper involves electrolytically dissolving impure copper material into solution. Pure copper is electrochemically deposited on an electrode by applying an electrical current through the solution. This removes impurities from the copper to achieve higher purity. However, the process is expensive and has a very high electrical demand.
How to Clean Military Copper With Lemon and Salt
Step 1: Wash the Piece
Always begin your cleaning session by washing the military copper item in warm soapy water with a soft sponge. This will remove dust and any greasy film on the surface.
Step 2: Make a Cleaning Paste
In a small bowl, mix two parts salt with three parts lemon juice to form a paste. If the paste is too runny, add more salt.
Step 3: Scrub the Copper
Use a sponge to spread the paste over the copper. Working in small circles, gently scrub the surface. Mix more paste if needed.
Step 4: Treat Stains
If stubborn stains persist, apply the paste and let it sit for five to 10 minutes before scrubbing. You could also cut a fresh lemon in half and dip it in table salt to clean the heavily stained areas.
Step 5: Rinse and Dry
Once the military copper is tarnish-free, rinse the piece in warm water. Use a lint-free towel to dry the military copper piece. Avoid air-drying copper: Allowing military copper to air-dry can result in water stains or tarnish from the reaction of the minerals in the water.
3 Ways to Prevent Military Copper Corrosion
Grease
By using some kind of grease, such as a layer of Vaseline, over the military copper you can prevent military copper corrosion. This isn’t suitable for all objects made of copper, but where you have military copper pipes in the basement, for example, it can prove to be an excellent solution. You do need to make sure that you cover all the pipe in the grease so you have an airtight coating over the metal for this to work.
Sealer
Employing a paint sealer to keep air off the military copper is another good way to stop military copper corrosion. This is a solution that will work with military copper objects, although in this case it will be for display objects rather than anything to be handled regularly.
Cleaning
With most military copper objects, regular cleaning using a salt or vinegar and baking soda paste is the answer. This will prevent any type of corrosion happening to the military copper as well as keeping the metal shiny. Clean monthly to achieve the best results. This takes time, but if done thoroughly military copper corrosion will never be a problem.
