We cannot perform machining on-site, but we need to engage in equal dialogue with the processing contractors.
We received a request for a quotation for machined products from a customer. The material is pure copper, and the machining requires black chromate surface treatment.

So why is surface treatment necessary for pure copper? I thought about the reasons a bit. Pure copper is a material that easily oxidizes in the atmosphere. We have even encountered cases where products changed color after being stored for just a few days post-processing. *For more details, you can view the content of the blog through the related link.
