Direct chill cast billet is manufactured by Luxfer MEL Technologies as the starting material for other magnesium products, such as sheet, forgings and extrusions. However, it has been frequently found that the cast billet is suitable for machining into prototypes, thus avoiding expensive tooling, and in some cases for production where the size of the finished item is outside economic casting or extrusion dimension or minimum economic production.
Cast billet is supplied to the compositional requirements but not the mechanical properties of the British/ASTM Standard for the corresponding wrought or cast alloy. With conventional casting alloys, if the billets were to be heat treated it would be expected that the specification minimum properties would be obtained though, due to the casting technique employed, no guarantee could be given.
Inspection standards for cast billet will be by agreement. Ultrasonic inspection to AMS-STD-2154 Class A or Class AA is available upon request. Temporary corrosion preventative surface treatments can be applied by agreement.
Nominal weight of available cast billet (kilograms per metre of billet length)
Alloy and size combinations without a listed weight may be available on inquiry.
