| 1) Remark: CuZn31Si1 (former designation: CuZn31Si) is a non-hardenable Cu-alloy. High hardness and strength values can only be reached by cold forming. Strength values between F38 and F60. Si reduce the sensitivity to stress corrosion. CuZn31Si1 has a good sliding behaviour. Processing properties: Hot forming: medium Cold forming: good Machinability: medium Brazing: medium Soldering: medium TIG-welding: good Polishability: very well Application: bearing bushings, guides, sliding elements |
