Lightness in the highly complex aviation industry

High-quality anodized coatings

One partner in the manufacturing process is BWB Surface Technology, where aluminium components are anodized. This electrolytic process creates a resistant oxide layer that provides corrosion protection and at the same time improves the appearance of the components. BWB's surface coatings ensure that the AC4 aircraft not only impress with their innovative technology, but also with their safety and durability.

Certified aviation expertise

BWB has many years of experience in the aviation industry and offers a wide range of coatings for the aviation industry, including anodizing coatings, hard anodizing and a wide variety of primers and paints. BWB Surface Technology works in accordance with the strict specifications of international aircraft manufacturers. The processes are certified in accordance with EN 9100:2018, which guarantees the highest quality standards. As a recognized partner in the entire supply chain, BWB is very familiar with the specific requirements and approval processes of the industry.

Advantages of anodizing for the aviation industry

• Corrosion resistance: Increases the service life of components, especially in damp and salty environments.
• Low weight with maximum protection: The thin oxide layer offers excellent protection without any significant additional weight.
• Electrical insulation: In certain areas (e.g. housings for electrical systems), the insulating effect of the anodized layer prevents unwanted short circuits.
• Improved adhesion for paints and adhesives: The microporous structure of the anodized layer facilitates the application of protective paints or functional coatings.
• Abrasion resistance: Anodized surfaces are more resistant to mechanical wear, e.g. caused by friction or particle abrasion.
