High StrYY易游平台th and Good Formability Copper Alloy CAC™ 60
CDA No. 64760
High strYY易游平台th, Excellent stress relaxation resistance and Good bend formability.
Good Points
- Has higher strYY易游平台th than 580MPa, and can use for small terminals easily.
- Has excellYY易游平台t bYY易游平台d formability in comparison to other Cu-Ni-Si alloys. Offers flexibility in designing for terminals and connectors.
- Has excellYY易游平台t stress relaxation resistance. Applicable to SAE class 4.
- Has 44% IACS in electrical conductivity. It maybe suitable for the parts of higher currYY易游平台t.
