Cupro B2 CuBe2 UBE2 Hard Copper Alloy
Cupro B2 CuBe2 UBE2
RWMA Class4 - C17200 - CW101C
Cupro B2 is a copper alloy with the highest hardness.
Very high mechanical properties with a reasonably good thermal and electrical conductivity.
Nitriding and case-hardening are not suitable.
40 - 41 RC is reached.
Optionally, case hardened or solution obtained condition (20 - 22 RC) will be delivered.
