Wrought magnesium alloys are manufactured in forms of rolled sheets and plates, extruded bars, rods and tubes, forged shapes.

Ductility of magnesium alloys in cold state is low; therefore these alloys are worked hot at the temperatures within the interval 570-890 °F (300-475°C).

Wrought Magnesium-Manganese Alloys (M1A) are non-heat-treatable.

These alloys are supplied in annealed conditions.

Magnesium-manganese wrought alloys have low mechanical strength combined with excellent weldability and corrosion resistance.

The alloys are used for manufacturing welded structures.

Wrought Magnesium-Aluminum-Zinc Alloys (AZ10A, AZ31B, AZ61A, AZ80A) are heat-treatable and may be strengthened by precipitation hardening (solution treatment followed by aging).

The alloys have good workability in hot state, moderate mechanical strength and good weldability.

Wrought magnesium-aluminum-zinc alloys are used for manufacturing aircraft fuselage, computer cases, speaker cones, super-plastic sheets, extruded plates, sheets and sections of moderate cost, rolled sheets and plates, photoengraving sheets.

Wrought Magnesium-Zinc-Zirconium-Thorium Alloys (ZK10A, ZK20A, ZK60A, HM13A, HM31A) are heat-treatable high strength alloys.

Zirconium is added to the alloys for refining Grain structure .

Zinc increases the strength of the alloys.

Wrought magnesium-zinc-zirconium-thorium alloys have very high mechanical strength combined with poor weldability and workability even in hot state.

The alloys are used for manufacturing high strength forged and extruded parts, bicycle frames, road wheels, helicopters gears, parts of satellites.
