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).
