Standards/specification
CuCo1Ni1Be / CuCo2Be ~ 2.1285 (DIN 17665 withdrawn, replaced by:)
~ CW103C / ~ CW104C (DIN EN 12163, DIN EN 12164, DIN EN 12167, DIN EN 12420)
~ C17510 / ~ C17500 (ASTM B441, ASTM B534); RWMA Class 3
Material properties
Age-hardened copper alloy with excellent thermal conductivity and electrical conductivity; with high values for mechanical strength and hardness, high softening temperature
Application examples
Injection molds, plastic mold making, tool making, hot runner nozzles, dies, die casting pistons, mold inserts, welding electrodes for resistance welding, electrode holders; energy technology, guide rails and slide elements in temperature-stressed areas
Processing
When hardened, good machinability with carbide tools, spark erosion possible; due to the beryllium content, protective measures are required to avoid the occurrence of dust/vapors. Process wet, ensure good cooling.
