1939 Made sand castings and die castings for aluminium alloy. The firm were pioneers of the modified process by which the excellent mechanical properties of the corrosion-resistant aluminium silicon alloys are obtained free from hot shortness and extreme fluidity. By adding to pure Alpax very small amounts of other metals which do not in any way affect corrosion-resistance, the firm has devised alloys which according to heat treatment fit them for more highly stressed parts[5]
