Abstract

The physical properties of malleable and grey cast iron are improved by the addition of 0,25-3 per cent of copper, 0,05-0,5 per cent of titanium and optionally 0,015-0,15 per cent of aluminium. High strength grey cast iron is made by using metal suited to the production of malleable cast iron, and by making additions to produce, by a treatment shorter than the usual annealing process, a grey cast iron. The copper and aluminium are added either in their single unalloyed state or combined in the form of alloys and the titanium can be added as an alloy such as ferro-titanium. For the production of malleable cast iron, the silicon or carbon content should be reduced to prevent the formation of primary graphite, but in the case of grey cast iron these contents should be increased, and the carbon or silicon content, or both, adjusted according to the section of the article to be cast. Specification 390,687 is referred to.
