Cupron solderability
Had to solder to Cu-Ni terminal lugs at one time. The solderabilty was what I would call lousy. Since I had no restrictions on what I could use I dipped them in a Nitric acid solution and immediately tinned them. This worked ok. Also tried rubbing with a rubber eraser, the kind with abrasive in it. That worked but not as well. Both methods are pretty much frowned upon in electronics though.

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
