2021 New Style Tin Plated Copper Sheet - Beryllium Copper Foil – CIVEN Detail:

Product Introduction

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

Beryllium bronze is a precipitation hardening alloy. After solution aging treatment, it has high strength, hardness, elastic limit and fatigue limit, small elastic lag, corrosion resistance and machining performance. Beryllium copper alloy is the material of submarine cable repeater structure, which is characterized by low temperature resistance, non magnetism, high electrical conductivity, impact and no spark. At the same time, it also has good fluidity and the ability to reproduce fine patterns. Beryllium copper alloy has been widely used in manufacturing industry because of its many superior properties. Strong conductivity, low temperature resistance, non-magnetic, high conductivity, impact and no spark. At the same time, it also has good fluidity and the ability to reproduce fine patterns.
