デュエルビッツ 入金方法od Formability Copper Alloy CAC™ 75
デュエルビッツ 入金方法od electrical conductivity
Excellent stress relaxation resistance and Good bend formability.
Good Points
- Has higher strength than 750MPa, デュエルビッツ 入金方法an use for small terminals suitably.
- Has high yield strength, equivalent to low bdellium copper alloys.
- Has about 3 times electrical conductivity of phosphorous bronze.
- Has excellent bend formability, which contributes to flexibility in designing due to smaller anisotropy.
- Has excellent stress relaxation resistance and is suitable for the automotive applications.
