Beryllium Copper Foil

Beryllium Copper Foil is a thin, flexible sheet made from a copper-beryllium alloy. It combines the excellent electrical and thermal conductivity of copper with the added strength, hardness, and fatigue resistance provided by beryllium. This makes it an ideal material for applications requiring both high performance and reliability.

 

Beryllium Copper Foil is a copper-based alloy characterized by a supersaturated solid solution, renowned for its amalgamation of mechanical, physical, chemical, and corrosion-resistant attributes. Upon undergoing solid solution and aging treatments, it attains high thresholds of tensile strength, elasticity, yield strength, and fatigue resistance, rivaling those of specialty steels. Concurrently, it boasts superior electrical and thermal conductivity, elevated hardness and wear resistance, as well as exceptional creep and corrosion resistance. This material is extensively utilized in the fabrication of diverse mold inserts, supplanting steel in the creation of high-precision and intricately shaped molds. It serves as a material for welding electrodes, die-casting machines, and injection molding machine punches, and is employed in wear and corrosion-resistant applications. Beryllium copper foil finds its use in micro-electromechanical brushes, mobile phone batteries, computer connectors, various switch contacts, springs, clips, washers, diaphragms, and membrane sealing products, among others. It constitutes an essential industrial material pivotal to the development of the national economy.
