Plating Recommendation for Non Magnetic, Corrosion Resistant, Scratch Resistant Finish
I am looking for a recommendation on what type of plating would meet the enclosed "wish list". Application is a small stamping (40,000 per month) made from low carbon steel.
Oxidation protection even in harsh environments
Non magnetic (definitely not Nickel !)
Very good thermal conductivity
High resistance to cracking or flaking even if the steel that it is adhered to is being bent or otherwise worked
Tolerates heat up to 250+ °C
Plating/Surface treatment process does not change magnetic performance of carrier
Thin, preferably (a lot) less than 0.5 mil thick
Non-toxic (final product)
Specific to APPI Std. PartsVery good electric conductivity
Low surface roughness
Ability to be soldered to with most regular solder types

The answer you are looking for could be a nickel alloy. High Phosphorous electroless nickel meets most of your wish list, non-magnetic, withstand heat etc.

Hi, Jon. I don't think anyone is going to improve on George's suggestion :-)
High phosphorous electroless nickel really sounds like the way to go.
