2.1247 (DIN 17666 : 1983-12) CuBe2 2.1247 DIN 17666 : 1983-12 Withdrawn without replacement Germany 3.2 1)
1) Remark: CuBe2 belongs to the hardenable, low-alloy copper alloys. It is an alloy with optimal hardening bar for highest requirement at hardness, elasticity, wear and fatigue strength. The strength grade lie between F45 and F130. CuBe2 possesses middle electrical and good thermal conductivity. No embrittling at lower temperatures (to -200 °C). No sensitivity in relation to stress corrosion. The destabilization temperature is approx. 350 °C. Manufacturing properties: hot and cold forming: well machinability: means hard and soft soldering: well gas-schielded arc welding: well polishing bar: well Application: For bearing jewel and screws, band and wires, diaphragms, unrests and pulling hurry for clocks, springs of all art. Elements for HF- and NF-special clutches, wear resistant snail and gear wheels, highly stressed massif parts, non-magnetic and transmit-safe tools.
