Copper Plate / Sheet

Copper plate is a high stability, low maintenance material, which excels in environmental protection, safety in use, easy processing and corrosion resistance. The classification of copper plates is very wide, including aluminum bronze plates, brass plates, tin bronze plates, silicon bronze plates, beryllium bronze plates, tungsten copper plates, red copper plates, red copper plates and oxygen-free copper plates, etc., each of which has different characteristics and application fields. Commonly used copper plate grades include H62, H65, H68, H70, H80, H90, C2600, C2680, C2700, C5210, C5191, C51000, QBe2.0, C1100, T2, etc.

The material properties of copper plates make them widely used in many fields. It has high electrical and thermal conductivity, second only to silver, but is relatively cheap. Copper is also very resistant to corrosion, especially in environments such as non-oxidizing acids, alkalis and seawater. In addition, copper is also easy to process and form. It has moderate strength and good plasticity, and can withstand hot and cold pressure processing with large deformation. Copper is also antibacterial and can inhibit the growth of microorganisms such as bacteria, which is very important for drinking water transmission, food utensils, marine engineering, etc. Copper is easy to weld and has good plating properties, and pure copper is a non-magnetic metal.

The physical and mechanical properties of copper plates are also excellent. Its density is 8.93 g/cm^3, melting point is 1084.88℃, and boiling point is 2595℃. The specific heat capacity of copper is 386 J/(kg·K), the linear expansion coefficient is 16.7×10^(-6)/K, the thermal conductivity is 398 W/(m·K), the resistivity is 16.73 nΩ·m, and the electrical conductivity is 103.06%JACS. In terms of mechanical properties, copper has a tensile strength of 209 MPa, a yield strength of 33.3 MPa, an elongation of 60%, a hardness of 37 HBS, and an elastic modulus of 128 GPa.

In the construction industry, copper plates are often used in architectural decoration projects such as roofs, walls, ceilings, etc., and are also used to make doors and windows, decorative lines, etc. In the machinery manufacturing industry, copper plates are used to manufacture mechanical parts such as bearings, gears, and bearings. In the electrical industry, copper plates are used to manufacture wires, cables, electrical contacts, etc. for power transmission and distribution. In shipbuilding, copper plates are used to make hulls, ship accessories, etc., using their corrosion resistance to resist the erosion of seawater and salt spray. In addition, copper plates can also be used to make musical instruments, clocks, and artworks.
