Elektron® WE43B is a high strength magnesium based casting alloy developed and patented by Luxfer MEL Technologies for use at temperatures up to 300˚C.
This alloy system maintains its good mechanical properties at elevated temperatures, without the use of either silver or thorium. The alloy is stable for long term exposure up to 250˚C. Elektron® WE43B has excellent corrosion resistance characteristics.
The excellent retention of properties at elevated temperatures will be of interest to designers of aeroengines and other power systems, helicopter transmissions, missiles, racing and high performance cars.
Fine grained and pressure tight with good casting characteristics.
Pattern makers shrinkage factor
Fully weldable by the tungsten arc inert gas (TIG) process, using filler rods of the parent alloy composition.
Elektron® WE43B castings, like all magnesium alloy castings, 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.
Normal protective treatments apply for Elektron® WE43B but some chromating baths may need to be modified for the satisfactory treatment of castings. Please refer to Luxfer MEL Technologies Design Guide.
