Surface Condition and Processing FAQ

Bright, annealed, hard, mirror, brushed, polished and coated describe different conditions and must be selected for function and downstream processing.

Forming needs elongation and lubrication, decoration needs appearance consistency, while welding and medical uses focus more on cleanliness and residue.

Surface processing can affect thickness, diameter, roughness, colour and adhesion and should be considered in tolerance.

Use samples, roughness, colour limits, defect criteria, coating requirements or a defined process for acceptance.

Decorative sheet, precision strip, bright wire, hydrogen-annealed wire, polished tube and copper-coated wire have distinct finish needs.

Provide substrate, target finish, roughness or sample, downstream process, packaging protection and quantity.
