About Heuberger Eloxal
A. Heuberger Eloxieranstalt GmbH is an Austrian family-owned company based in Graz that has specialised in the surface finishing of light metals, especially aluminium, since 1948. Its range of services includes technical anodising (Eloxal), pre-anodising, partial anodising and combined processes, hard anodising and hard anodising in black, the Color colour process, the Sandalor process, organic dyeing, mechanical pre-treatment and pickling passivation with Surtec650. With Mag-Pass-Coat, the company offers a chrome-free passivation process for magnesium materials. These processes are complemented by surface engineering, prototypes and sample parts, care and maintenance as well as logistics and special packaging. Customers come, among others, from mechanical engineering, mechatronics, automotive, aviation, aerospace, the rail industry, the lighting industry, architecture and design. Maximum component dimensions for anodising are 6500 x 1500 x 550 mm. The company is ISO 9001 certified and has been recognised several times for environmental performance and innovation.
