Description
Beryllium Copper Foil
Beryllium Copper Foil is one kind of supersaturated solid solution copper alloy which combined very good mechanical ,physical, chemical properties and corrosion resistance. It has high intensity limit, elastic limit, yield strength and fatigue limit as special steel after solution treatment and aging. It also has high conductivity, thermal conductivity, high hardness and wear resistance, high creep resistance and corrosion resistance for which it has been widely used to replace steel in the manufacturing of various types of mold inserts, producing precision and complex shaped molds, welding electrode material casting machines, injecting molding machines’ punches and etc.
Beryllium Copper Foil’s application is micro-motor brush, cell phone batteries, computer connectors, all kinds of switch contacts, springs, clips, gaskets, diaphragms, film and etc.
It is indispensable an important industrial material to the national economy
