Researchers in China say they have developed supersized magnesium alloy auto parts that could significantly reduce the cost of making cars and promote lightweight vehicle designs. The scientists produced the two giant parts – a car body and a battery box cover – from a single mould in one casting. Each part measures over 2.2 square metres (23.7 sq ft) – the first of their size to be made from magnesium alloy, according to a news release from the National Engineering Research Centre for Magnesium Alloys (CCMg) at Chongqing University on June 27.

Chongqing Millison Technologies provided the die casting system used for processing, while Boao Aluminium Manufacturing has experience in developing magnesium alloy dashboard and seat frames. They used high-pressure casting to create the two parts using a technology similar to Tesla’s “gigacasting” process. It involves injecting molten metal into a steel mould and filling it under high pressure before cooling.
