1 Technical Information Material Data Sheet Magnesium Mg KG High performance materials in form and function

2 2 Magnesium and Magnesium wrought alloys are the ideal material for extremely light components. Their most important properties are: low specific weight, good for hot forming, excellent machining properties as well as low internal stress. The magnesium production range of includes hand forgings up to a weight of 300 kg and die forgings from 5 g up to 300 kg. The largest projected area amounts cm 2, for a greatest length of mm and a maximum width of mm. Furthermore produces extruded magnesium profiles for example round bars with a maximum diameter of 160 mm, tubes with a maximum diameter of 220 mm, solid and hollow profiles as well as welding electrode rods and wires up to 13 m length. Fields of applications Aerospace Industry: Structural parts Casings Gearbox casings Vehicles: General Engineering: Motorcycle wheels Rotors for Compressors Pumps Textile machine components Printing press components

Due to the crystal structure, the shown magnesium alloys have diagonally to the fiber under tensile stress and along the fiber under compressive stress 30% to 50% lower R p0.2 values, as under a tensile load parallel to the fiber. Solutions with magnesium wrought alloys Construction engineers have a wealth of economical design options at their disposal, from die-forged parts to extrusion products. We have developed a special continuous casting technology so as to further improve resistance to corrosion. This enables us to produce alloys in high purity quality, i.e. with very low levels of Fe and Ni content. We have more than seven decades of experience in the production and finishing of this material. Gearbox Cover mm x 560 mm x 220 mm 43,0 kg Please note Due to their electronic potential, magnesium alloys are sensitive to contact corrosion and must therefore be protected by means of insulation layers in the case of direct contact with other metals. What is more, general resistance to corrosion only applies to a limited extent. An inorganic and/or organic anti-corrosive coating should be applied.
