Technical coating processes

Anodising and hard anodizing

When aluminium is anodised, the top layer is transformed into a robust oxide layer. This layer provides reliable protection against wear and corrosion and at the same time improves the surface hardness. In addition to classic anodizing, BWB’s range of services also includes specialized processes such as hard anodizing, Ematal and Heloxal.

Anodising

Chemical nickel plating

Electroplating processes not only protect metal components from wear and corrosion, but also optimize their electrical and thermal conductivity. Electroless nickel plating produces hard, non-magnetic and solderable layers that are particularly impressive in applications with high technical requirements.

Electroplating

Passivation and chromating

Passivation and chromating refers to the application of a non-metallic protective layer that prevents oxygen corrosion and extends the service life of metallic materials. In addition to classic chromating with Alodine 1200 S Aero, the BWB Group also offers Cr(VI)-free alternatives such as SurTec 650 and Bonderite M-NT 400 – for environmentally friendly and future-oriented applications.

Passivation & chromating

Certified quality leader

The continuous striving for improvement is reflected in the quality of BWB. Numerous certifications such as NADCAP (CP/SE/NDT), EN 9100 and ISO 13485 confirm the high quality of BWB services for technically applications in aviation, mechanical engineering and medical technology.
