Abstract

An alloy for addition to a molten iron bath to produce bendable cast iron has a composition within the following range in per cent by weight: .Si.40.0-80.0 .Mg.5.0-30.0 .Rare earth metals.0.5-6.0 .Fe.and impurities the balance The alloy may be added to a bath of hypoeutectic iron in amount between 8 and 30 lbs. per ton of iron, the iron being at a temperature of 1350-1450 DEG C. Pig iron containing less than 0.5% Mn may be melted in the presence of a flux together with ferro-silicon to provide a melt having a silicon content of 1.0-1.5%, and the addition alloy is introduced by plunging therein an apertured cage of iron or steel containing the alloy. The production of an iron of the following composition is referred to. .C.3.1 -3.2 .Si.1.5 -2.0 .Mn.up to 0.3 .S.up to 0.01 .P.up to 0.05 .Mg.0.05-0.06 .Ce.0.015-0.25 .Other rare earths.0.015-0.025 Specification 630,070 is referred to
