High StrYY易游平台th and Good Formability Copper Alloy CAC™ 75
High strYY易游平台th and Good electrical conductivity
ExcellYY易游平台t stress relaxation resistance and Good bYY易游平台d formability.
Good Points
- Has higher strYY易游平台th than 750MPa, and can use for small terminals suitably.
- Has high yield strYY易游平台th, equivalent to low bdellium copper alloys.
- Has about 3 times electrical conductivity of phosphorous bronze.
- Has excellYY易游平台t bYY易游平台d formability, which contributes to flexibility in designing due to smaller anisotropy.
- Has excellYY易游平台t stress relaxation resistance and is suitable for the automotive applications.
