Kirin's treatment (chrome-free)

Copper and copper alloys are treated with a chrome-free KIRINS process. Fully compliant with RoHS.

We will perform a chrome-free Kiring treatment (i.e., pickling and discoloration prevention treatment) on copper and copper alloys. Conventional Kiring treatment involves immersion in hexavalent chromium solution. I believe there are many vendors who are lagging behind in this regard. Please let us handle the treatment for you.
