I am trying to cost-reduce a current part. The part is the lid of a 19" rack assembly. Currently the part is made from 1mm thick zintec and is painted. I would like to remove the paint to save money, but very often zintec often doesn't look that great on its own (often gets scratched up by the supplier). I have considered using stainless steel 430 DP1 instead (we make the chassis part of this product from this), but this picks up fingerprints and looks awful after a while. Can anyone suggest a low-cost sheet material that is aesthetically pleasing without having to apply a special finish or surface treatment? One other question - we deply these products to hot humid countries, and my company has disapproved of zintec in the past because the edges where the metal is cropped will corrode after a while. My experience tells me that every VCR, DVD player, washing machine etc etc etc in the world is made from this stuff. Is their disapproval an overreaction?
