Surface treatments of various non-ferrous alloys
Our products are usually delivered to you with a final surface treatment. This can be done in two ways:
- Without adding to the original material with processes such as tribofinishing, shot blasting, pickling or polishing. The aim of this basic operation is to make the surface of the parts homogeneous in roughness.
- With input on the surface to modify the appearance, colour or technical characteristics of the parts (electrical conduction, corrosion resistance etc...)
