Beryllium bronze: contains beryllium, copper, and other alloying elements. It has good elasticity, conductivity, and corrosion resistance, and is commonly used in electrical connector application environments that require high conductivity and elasticity. The addition of beryllium improves elasticity and fatigue resistance.

Beryllium cobalt copper: Contains elements such as beryllium, cobalt, and copper. It has excellent elasticity and fatigue resistance, suitable for application environments that require high reliability and long life. The addition of cobalt increases the hardness and fatigue resistance of the alloy.

Chromium zirconium copper: Contains elements such as chromium, zirconium, and copper. It has superior elasticity, conductivity, and corrosion resistance, suitable for high temperature and corrosive application environments. The addition of chromium and zirconium improves the alloy's high temperature and corrosion resistance.

Stainless steel: containing elements such as iron, chromium, nickel, etc., it has good corrosion resistance, strength, and hardness, and is suitable for stable operation in humid or corrosive application environments

High temperature alloy: contains high-temperature stable elements such as nickel, chromium, tungsten, etc. Excellent high-temperature stability, suitable for applications that require working in high-temperature environments

Independent work ability

Radial characteristics: Each spring coil is designed to independently respond to radial forces, ensuring that the force is evenly transmitted to each coil when the spring is compressed or stretched, avoiding excessive or insufficient local forces. The load can be evenly distributed on each spring coil to prevent instability or excessive deformation of the spring system due to uneven load.

Axial characteristics: The design of the spring contact finger enables each spring coil to independently respond to forces in the axial direction, without being significantly affected by adjacent coils. This ensures a uniform distribution of axial load, whether subjected to axial pressure or axial tension, to maintain uniform deformation of the spring and prevent problems caused by excessive local force.

Surface Treatment

Gold plating: Gold plating has a high cost, but it is more stable in corrosive environments and less sensitive to corrosion. It is the first choice in corrosive environments

Silver plating: The choice of silver plating coating for spring contact finger products is due to silver being an excellent conductive material, while surface coating silver plating is used to improve conductivity and oxidation resistance; Moreover, the cost of silver plating is more economical
