Types, grades, and application areas of copper

1、 Purple copper
Purple copper, also known as pure copper or red copper, is a copper alloy with a copper content of up to 99.9%. The common grades include T1, T2, T3, etc., where the larger the number, the lower the purity of copper. Copper, with its excellent conductivity and thermal conductivity, has a wide range of applications in various fields such as wires and cables, electrical components, and heat sinks. At the same time, purple copper is often used by skilled artists to create handicrafts and musical instruments, such as brass instruments, bronze statues, etc., showcasing its unique artistic charm.

2、 Brass
Brass, an alloy composed of copper and zinc, has various grades, such as H62 (containing 62% copper) and H65 (containing 65% copper). With excellent processing performance and corrosion resistance, brass has been widely used in various fields such as building hardware, valves, pipelines, and bathroom equipment. At the same time, it is often used to create decorations and musical instruments, such as copper bells and drums, adding a unique color to people's lives.

3、 Bronze
Bronze, an alloy composed of multiple elements such as copper, tin, and lead, varies in specific grades depending on the composition of the alloy. With excellent strength and wear resistance, bronze plays an important role in the field of mechanical manufacturing, such as the manufacturing of gears, bearings, and fasteners. Meanwhile, its corrosion resistance also makes bronze suitable for the manufacturing of ship parts and seawater desalination equipment.

4、 White copper
White copper, with nickel as the main additive element, has formed grades such as B10 (containing 10% nickel) and B15 (containing 15% nickel). This copper alloy is not only corrosion-resistant, but also has excellent strength and toughness, so it is often used to manufacture high-precision products such as navigation instruments, precision instruments, and medical equipment.

5、 Beryllium copper
Beryllium copper, with beryllium as the key additive element, endows it with high strength, high elastic modulus, and excellent electrical and thermal conductivity. This makes beryllium copper shine in the manufacturing of high-speed cutting tools, molds, and contacts that require high wear resistance and precision.

6、 Oxygen free copper
Oxygen free copper stands out with its extremely high purity and low oxygen content, demonstrating outstanding electrical and thermal conductivity. This type of copper is mainly used to manufacture high-quality products such as electrical components, cables, and wires.

In short, there are many types of copper, and each copper alloy has its unique properties and specific application areas. In industrial production, it is crucial to choose appropriate copper alloy materials to ensure that various application requirements are met. At the same time, copper has extremely high recycling value in the industrial field, which has also spurred the development of the industry for recycling copper and copper alloy scraps.
