The lightest structural metal

As a world leader in the development and supply of high-quality extruded products, we operate two dedicated presses to supply a full range of extruded magnesium alloys and to develop new alloys for future applications. These lightweight alloys are used as forging feedstock, as a base material from which to machine components, or as custom shapes to integrate directly into a component. Our regulatory and export control department is dedicated to ensuring compliance with various laws and regulations.

Advantages of magnesium

Lightweight extruded magnesium alloys can be shaped into plate by rolling and extruded into both solid and hollow profiles. These can be further shaped using forging, pressing, bending or simply machining from solid.

Magnesium has inherent screening properties, useful for electronic enclosures, and offers good thermal conductivity for heat dissipation.

Magnesium alloys have excellent vibration damping properties.

Modern alloys have positive corrosion resistance. For more severe environments there are a range of surface passivation and top coat treatments commercially available.

Extruded magnesium alloys have comparable properties with other structural metals, with the added advantage of superior performance at elevated temperatures, including good creep resistance and tensile strength.

For bars with equivalent weight and width, magnesium is 18 times stiffer than steel and double that of aluminium. With only small increases in cross section, it is possible to redesign parts that offer 20–25% weight savings over aluminium equivalents and 65–70% weight savings when substituting steel designs.

Magnesium alloys are the easiest of all structural metals to machine. Advantages include low power consumption (45% less than aluminium), fast machining rates, excellent surface finish, reduced tool wear and well broken chips.

Extruded magnesium products

Luxfer MEL Technologies provides highly customised engineering solutions through a dedicated 2,750t hydraulic extrusion press, capable of manufacturing custom round bars, square and rectangular sections, profiles and solid or hollow shapes.
