C17200 Beryllium Copper Properties Provided by Changzhou Guangfang Metal 81185656
Beryllium copper alloys combine excellent mechanical, physical, and chemical properties. After heat treatment (solution treatment and aging), they exhibit high strength, elastic, yield, and fatigue limits comparable to special steels. Additionally, they possess high conductivity, thermal conductivity, high hardness, corrosion resistance, wear resistance, good casting properties, non-magnetic characteristics, and are non-sparking upon impact. These alloys are widely used in industries such as mold making, machinery, and electronics.
No sand holes, blow holes; balanced hardness; dense structure; high strength; excellent thermal conductivity; good electrical conductivity; corrosion resistance; wear resistance; good machinability; stable performance under high pressure conditions; non-magnetic; good polishing properties; good anti-adhesion properties.

Usage

Injection molds and high-pressure blow molds, mold inserts, rapid cooling, aluminum alloy mold inserts, enhanced strength, wear resistance, and shortened injection cycle, hot runner nozzles, electrode and punch materials, non-magnetic molds, non-magnetic tools, high thermal conductivity bearings, capable of producing surfaces with extremely high surface accuracy.
