Plating Recommendation for Non Magnetic, Corrosion Resistant, Scratch Resistant Finish


(2001)

Plating recommendation.

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.

"Wish List"

Adheres very well to low carbon steels (1008, 1010, 1018) and different grades of magnetic temperature compensation material (TC30, TC32 etc)
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
Scratch resistant
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)
Cheap

Specific to APPI Std. Parts

Very 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.
