Rio Tinto’s metallurgical experts have designed the alloys for the semi-solid Rheocasting process offered by Comptech, to meet the requirements of producing large, specialised single piece designs, known as giga-casting.
The alloys offer high strength, electrical and thermal conductivity properties, while Rheocasting allows fast, low cost production of advanced lightweight designs. The products are currently undergoing qualification with automakers in Europe.
