Cupro B2 Material Properties: Hardness is the highest copper alloy. 40 - 41 RC is reached. Optionally, case hardened or solution obtained condition (20 - 22 RC) will be delivered.

Cupro B2 Areas of Application:
•Flash welding dies, rim and chain welding
•In the plastic moulds as chill plates and inserts in the moulds, cooling pins and neck rings or bottom plates for blow moulds of plastic bottles

•Parts for electrical components
•Safety tools due to non-sparking, non-magnetic and corrosion resistant features.
