With the development of the electronics industry, copper and its alloy connectors have become important foundational materials. The modernization of connectors demands higher and newer requirements for copper alloy materials. They not only need to possess high electrical conductivity, corrosion resistance, oxidation resistance, excellent stamping performance, and good bending properties, but also need to have a high yield strength ratio, excellent elasticity, and stress relaxation resistance. Additionally, the material should have a relatively low cost.
Copper deep drawing refers to a process wherein copper or copper alloy materials are subject to deep stamping. Deep drawing is an important metal forming technology, commonly used to process metal sheet materials into parts with certain shapes, depths, and dimensions, such as cylindrical, box-shaped, or other complex-shaped workpieces.
In copper metal processing, copper deep drawing can be divided into hot stamping and cold stamping processes based on the processing temperature of the stamping. The former is suitable for the processing of sheet materials with high deformation resistance and poor plasticity. The latter is conducted at room temperature and is the commonly used stamping method for copper deep drawing.
The surface and internal properties of the sheet material for stamping have a significant impact on the quality of stamped products. During copper metal processing, the thickness of the stamped parts needs to be accurate, without scratches or surface cracks, etc. To avoid uneven deformation, the sheet material should have a high uniform elongation rate during the stamping process. To prevent subsequent deformation of components, the work hardening of the sheet material used for stamping should be relatively low.
Copper is closely related to humans and non-ferrous metals. It is not only rich in natural resources but also possesses excellent properties such as good electrical conductivity, thermal conductivity, ductility, corrosion resistance, and wear resistance. Deep-drawn copper parts are widely used in fields such as power, electronics, energy petrochemical, mechanical metallurgy, transportation, light industry, emerging industries, and high-tech sectors.
