Unifont

Unifont® – high strength and regenerative powers
Unifont alloys offer high strength without heat treatment and outstanding casting properties, but limited shaping properties. They are used for components which are often large and difficult, especially in circumstances which require high strength levels: in mechanical engineering, domestic appliances and medical technology. Thanks to their self-hardening character, they regenerate themselves after overloads, just like Castadur.

Nature's role model: the water lily which closes its petals for protection at night and only opens them again when the sun rises.

Unifont®-90 [ AlZn10Si8Mg ]

Areas of use
Heavy casting, mechanical engineering, model/mould construction, optics/furniture, textile industry, hydraulic casting, domestic appliances, defence engineering.

Distinguishing characteristics
Self-ageing alloy with very good strength and elongation properties, especially in low-pressure die casting. Very good mechanical polishability and machinability. Good weldability. Aged again following e. g. thermal loading from welding. Casting properties similar to Silafont-30.
