CuCo2Be—C17500 (CDA 175) Cobalt Beryllium Copper is primarily utilized in the industry applications that require most highly thermal or electrical conductivity, which features a cobalt alloying addition (2.40-2.70%). C17500 also Offers good strength and hardness characteristics coupled with conductivity in the range of 45-60 percent of copper with ultimate tensile and hardness properties approaching 140 ksi and RB 100 respectively.
Typical Application for C17500 Cobalt Beryllium Copper Alloys:
Electrical Industry:Fuse Clips, Switch Parts, Relay parts, Connectors, Spring Connectors
Fasteners:Washers, Fasteners
Industrial:Springs, Seam Welding Dies, Resistance Welding Equipment, Resistance and Spot Welding Tips, Tooling for Plastic Moulds, Die--Casting Plunger Tips.
Typical Physical Properties:
Density (g/cm3): 8.83
Density before age hardening (g/cm3): 8.75
Elastic Modulus (kg/mm2 (103)): 14.10
Thermal Expansion Coefficient (20 °C to 200 °C m/m/°C): 18 x 10-6
Thermal Conductivity (cal/(cm-s-°C)): 0.48
Melting Range (°C): 1000-1070
Note:
1). the units are based upon Metric.
2). the typical physical properties apply to age hardened products.
