Types and classifications of copper (rolled copper products)



Roughly classified by manufacturing method, copper can be divided into rolled copper products and cast products, among which rolled copper products can be divided into the following categories. Rolled copper has the shapes of plates, strips, rods, wires, tubes, busbars, etc.
Pure copper
There are oxygen-free copper, tough copper and deoxidized copper, and the difference between these three types is that they contain oxygen due to the manufacturing method. Copper has a purity of more than 99.9% and has excellent electrical and thermal conductivity, but its strength is weaker than other metals.
High copper alloy
Alloys with high copper content, such as beryllium copper, titanium copper, zirconium copper, tin-containing copper, iron-containing copper and Corson alloy, increase strength without significantly compromising the inherent high electrical and thermal conductivity of copper. However, in order to improve mechanical properties, the amount of added elements increases, and as a result, the electrical conductivity tends to decrease. Some have high strength of more than 685N/mm2, while others have high recrystallization strength and excellent heat resistance.
Brass (brass)
Brass (also known as brass) is known as the most commonly used copper. There are red bronze, detonator brass, 73 brass, 64 brass, 65:35 brass, free-cutting brass, naval brass, admiralty brass, aluminum brass, high-strength brass, etc. The base is a copper-zinc alloy. Then Pb, Sn, Al, etc. are added to make each material unique.
Bronze
There are "tin bronze" which is a Cu-Sn copper alloy, "phosphorus bronze" with a small amount of "phosphorus" (P) added, free-cutting phosphor bronze, aluminum bronze, etc.
Copper-nickel alloys
Copper-nickel alloys include white copper, white copper, nickel silver, fast-cutting nickel silver, etc. As you can easily imagine from the word "white" above, these are white copper alloys.
