The General Motors China Advanced Technical Center recently declared its formability and micro-foundry lab completed the initial low-pressure casting of a magnesium part.
The ATC specialists melted and casted the magnesium ingot materials producing a prototype magnesium alloy control arm used in vehicle chassis systems. It is with 30% lighter than the one made of aluminum, which translates in improved fuel efficiency. In the future cars will be made of more magnesium materials, resulting in 7% fuel economy improvement for every 150-kilogram (330 pounds) reduction in weight.
“The successful production of a part made from magnesium alloy is an important breakthrough for the ATC in lightweight automotive materials research. Satisfying the demands of our customers through new technological achievements is significant for GM’s ongoing growth in China and the Chinese automotive industry,” said ATC.
The Advanced Materials Laboratory is part of the first phase of the ATC, and it includes battery material lab, a battery cell testing lab, cell fabrication lab and metallography and electrochemical lab. The first phase focuses on lightweight materials (magnesium) and battery cells to improve EVs and other advanced technology vehicles.
