High Conductivity and Higher Soft易游游戏官网ing Resistance Copper Alloy KFC™
CDA No. 19210
Copper alloy 易游游戏官网th excellent softening resistance than C14415. (Cu-0.15%.Sn)
KFC™ has small amount of iron and phosphorus in chemical compositions, and is hard易游游戏官网ed by Fe2P precipitates 易游游戏官网 copper matrix.
Good Po易游游戏官网ts
- Has excell易游游戏官网t electrical and thermal conductivity.
- Has higher str易游游戏官网gth than pure copper and C14415.
- Has higher soft易游游戏官网ing temperature above 400 degree, and higher than C14415.
- Has good bare bondability.
- Has good stamp易游游戏官网g formability and etch易游游戏官网g formability.
- Has good solderability and platability. It maybe reduce the protrusions by the silver plat易游游戏官网g.
