Chemical Blacking

On Steel Or Stainless Steel Articles

This process provides a black oxide finish which is mainly applied to tools, small arms or semi-decorative articles made from Iron or steel. The process gives a very uniform finish with a jet black colour on most surface textures.

In relation with conventional oxidizing methods, the coating has increased abrasion resistance and has an improved appearance.

Depending upon the use of the components and the corrosion resistance required, immersing in dewatering oil, heavy oil or wax will suffice.

On Copper Or Copper Plated Articles

This is a non-electrolytic process which provides a very adherent coating with a jet black finish. The finish itself will withstand temperatures up to approximately 200°C. The chemical blackening gives good corrosion resistance to salt spray on copper based alloys. This protection can be greatly improved by immersing the components in oil, lacquer or wax due to the absorptive nature of the coating.

Chemical black can operate on almost all alloys containing from 65 to 100% copper. For the treatment of steel components, a minimum thickness of 5 microns (0.0002”) or more of copper must be applied.

It's a good company. No major issues. There's no reason why I wouldn't recommend them.
Their prices are good and their delivery/lead times are excellent
Good technical knowledge, service and cost.
I always do recommend South West to others.
Good company, would certainly recommend you.
