Kunshan Ruizhengyuan Electronics Introduction: What are the characteristics of copper processing for stamping products?

The core feature of copper processing stamping parts is "excellent electrical and thermal conductivity+good ductility+strong corrosion resistance", and it is easy to process and suitable for various stamping process requirements.

1. Excellent physical performance and adaptability to functional requirements.

With outstanding electrical conductivity, it is the material with electrical conductivity second only to silver in common metals, and is suitable for manufacturing electrical connection stamping parts (such as terminals and contacts).

Good thermal conductivity, can quickly transfer heat, can be used for heat dissipation stamping parts (such as heat sink, heat conductive gasket), to avoid workpiece failure due to high temperature.

With good diamagnetism, it is suitable for manufacturing precision electronic stamping parts without magnetic requirements, and does not interfere with the magnetic field environment of equipment.

2. Good plasticity and formability, easy to realize complex stamping.

Copper has strong ductility and low yield strength, and can withstand various stamping processes such as stretching, bending, blanking and deep drawing.

It can be processed into thin-walled and complex-shaped stamping parts (such as special-shaped conductive sheet and deep-cavity copper sleeve), which is not easy to crack and damage and has high forming accuracy.

Excellent cold working performance, no need for complex preheating treatment in stamping process, reducing production energy consumption and process complexity.

3. Strong corrosion resistance and long service life.

Copper can form a dense oxide film in dry air and fresh water environment, which can effectively resist corrosion and is suitable for stamping parts (such as connector housings and water pipe joints) in outdoor or humid environment.

It has good resistance to various chemical media (such as weak acid and weak alkali). Compared with steel stamping parts, it does not need additional complicated antirust treatment and has low maintenance cost.

Some copper alloys (such as brass and bronze) have better corrosion resistance and can adapt to more severe working conditions (such as marine environment and chemical equipment accessories).

4. The subsequent processing is convenient, and the function expansibility is strong.

The surface is easy to be plated, brazed, welded and other subsequent treatments, which can improve the conductivity, wear resistance or aesthetics (such as gold-plated copper terminals and welded copper joints).

Good machinability, if finishing (such as drilling and tapping) is needed after stamping, it can be realized quickly and the machining accuracy is easy to control.

5. Limitations need to be noted

The cost is higher than steel, aluminum and other materials, so it is necessary to balance the cost and performance requirements in mass production.

The strength and hardness are relatively low, and copper alloys (such as tin bronze and beryllium bronze) should be selected for heavy-duty and wear-resistant scenes, or strengthened by heat treatment.
