Hi folks! Cupron is a member of the cupronickel family and has all the
joyful solderability issues/constraints of nickel due to the percentage of
nickel contained in the alloy. A cupronnickel alloy is difficult to solder
using traditional electronics soldering practices.

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

Subject: [TN] Cupron solderability
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
