Trivalent chromating process availability and knowhow [India] 

++++

We are an automobile ancillary manufacturing fuel management parts made of aluminium alloy (adc-12) and zinc alloy (mazak). We chromate our machined parts with hexavalent chromium for surface treatment purposes. However now we have heard from our customers that trivalent chromium is a better option than hexavalent chromium from the enviromental aspect. Kindly let us know of the process of trivalent chromating.
