Gigacasting Rewrites Which Aluminium Alloys Get Specified
A single rear underbody casting replaces around 70 stamped parts, and the alloy has to fill a mould several metres across without cracking or needing heat treatment afterward. Conventional die-cast alloys cannot do it. The grades that can are proprietary, high-purity and supplied by a handful of producers who developed them alongside the press builders. Chinese vehicle makers adopted the technique fastest, and Chinese alloy suppliers grew with them. European and North American programmes are following on later platforms, which means the qualification advantage is already several years old by the time competitors arrive.
