"Coating anti-scratch"



 

Hello,

I'm working on a fixture. This fixture (made in metal; soft metal) have to lock a part. This part is on metal too (European norm: S300pb, American norm: 1008 (I think)) and chromium coated. The problem is that the fixture scratches the part because it's a contact metal-metal. I wondered if it was not possible to coat the fixture to not scratch the part. If yes, with which material? If not, on which material I have to make my fixture?

Thank to answer.

You have not provided enough specifics to give a real answer, but, tin or cadmium or silver are all relatively soft and should not be able to scratch a steel part.

Christophe:
I would also add copper as a good choice to the metals suggested by Mr. Watts. Also, could I ask why does your fixture have to be metallic. Can't it be made out of a rigid plastic like Nylamid or something similar. This would certainly be more gentle to your part.
