Corson Alloy NKC286
NKC286
High Strength Corson Alloy for Electronic Parts
(UNS Alloy No. C64728)
Overview
NKC286 is a Corson alloy combining high strength, high electrical conductivity, and excellent bend formability.
Conformant with JASO (Japanese Automobile Standards Organization) standard JC400, it is ideal for in-vehicle applications demanding particularly high strength. It is also available with reflow tin plating.
