KFC CDA
No. 19210 |
|
KFC
is precipitation hardened copper alloy containing a small
amount of Fe and P precipitated and dispersed a trace of
Fe-P compounds to achieve high strength. |
|
Features |
|
1.
Excellent
electrical and thermal conductivity.
2.
Higher
strength than copper such as OFC, TP and DHP.
3.
Excellent
stress corrosion cracking resistance.
4.
Good
solderability.
5.
Good
platability.
6.
Good
heat resistance (over 4000C).
