Technical characteristics

The alloy is characterized by high percentage content of magnesium and silicon. Responds well to heat treatment — annealing with subsequent aging, resulting in higher ductility and toughness. Because of the reduced amount of iron lends itself well to processing on machine tools. Amenable to hot plastic deformation, has excellent casting properties (good fluidity and low shrinkage) and high corrosion resistance and weldability.

Application

From this material produce (mainly methods of casting under pressure) gear box, housing, flywheels, oil trays, brackets along with various fittings and pump bodies, chassis, trucks, aircraft and rocket components, and other structural elements that require high strength.
