WE54 is a high strength fully heat treatable magnesium based casting alloy for use at temperatures up to 300°C. The alloy develops high strength properties at elevated temperatures, without containing either silver or thorium.
APPLICATIONS
The excellent retention of properties at elevated temperatures and improved corrosion resistance will be of interest to designers of power systems, transmissions, missiles, high performance cars and other high technology applications. Prolonged use of this alloy (ie in excess of 1000 hours) at temperatures in the range 100°C–250°C may result in the loss of ductility. An alternative alloy is WE43.

WELDABILITY
Weldable by the tungsten arc inert gas process (TIG) with a filler rod of the parent alloy composition. Castings should be heat treated after welding: 1 hour at 510°C, quenched or air cooled and 16 hours at 250°C.
MACHINING
WE54 castings, like all magnesium alloys, machine faster than any other metal. Providing the geometry of the part allows, the limiting factor is the power and speed of the machine rather than the quality of the tool material. The power required per cubic centimetre of metal removed varies from 9 to 14 watts per minute depending on the operation.
CORROSION RESISTANCE
Additions of yttrium contribute to the excellent corrosion resistance characteristics of WE54 to the extent that it is of a similar order to aluminium casting alloys under salt spray conditions.

The beneficial effects of rare earth on the non-ferrous materials in the magnesium alloy are the most obvious. Appropriate content of rare earth can refine the grain size of magnesium and magnesium alloys. The first is to refine casting grain. Rare earth elements refine the mechanism is not the role of heterogeneous nucleation of magnesium alloy casting organizations. The mechanism of rare earth elements on the grain refinement of magnesium and magnesium alloy crystallization forefront of undercooling increases.
Alloying magnesium with rare-earth elements (RE) is used to develop light construction alloys for the applications at elevated and high temperatures. Generally, RE elements in Mg have relatively high solubility decreasing significantly with decreasing temperature. Therefore age hardening is possible in these alloys to improve mechanical properties.
Magnesium-Neodymium, Magnesium-Zirconium, Magnesium-Lanthanum Alloy, Mg-Ce Alloy, Magnesium-Scandium, Magnesium-Gadolinium, Magnesium-yttrium are high purity RE alloys manufactured by XYMCO. As master alloys, they can be used for grain refining, hardening, and improving alloy performance by enhancing properties such as ductility and machinability. Available Magnesium-Rare Earth alloy forms include sheets and plates, discs, rods, tubes, and other shapes. XYMCO can produce Magnesium-Rare Earth alloys in various standard ratios of Mg/RE; Customized Magnesium-Rare Earth alloys compositions are also available. Advanced chemical analysis is available for all Mg-RE alloys by best demonstrated techniques including X-ray fluorescence (XRF), glow discharge mass spectrometry (GDMS), and inert gas fusion.
Application: As the master alloy, magnesium-rare earth alloy can be used as the addictive to alloys, for the refining, hardening and machinability. Magnesium rare earth master alloys can be used for rare earth-containing cast magnesium alloys and wrought magnesium alloys. Improve the alloy's high temperature resistance, corrosion resistance and creep resistance; at the same time refine the alloy structure, improve the strength, casting properties and processing performance significantly improved.
