Cupron solderability

Is cupron – cupro-nickel? It is very difficult to wet. When we do this we usually put kapton tape on top of the part to hold it down because the solder joint is so weak. Regards Steve Kelly

Hi folks,

Anyone familiar with Cupron and if it is solderable?

Checked Matweb, but no indication on solderability.  Basically, it is a copper and nickel alloy, although some show an iron component.  A quick test here with a sample showed no wetting action, even with an aggressive flux.  There is no surface finish to protect the copper or nickel from oxidation.

Thanks,

Glenn
