Abstract
Alloys of aluminium, silicon, and antimony are "modified" by adding sodium carbonate or bicarbonate, preferably in the anhydrous form, to the molten alloy and stirring it into the molten alloy at a temperature within 50 DEG C. on either side of 1000 DEG C. The alloy preferably contains 5-15 per cent silicon and not more than 3 per cent antimony, the treatment of an alloy of aluminium with 7-8 per cent silicon and 0,5-1 per cent antimony being described. The treated alloys may be used for cast bearings, e.g. as bushes or liners for journal bearings. According to the Provisional Specification the modification may be effected by treatment with the alkali metals or their salts. Specification 305,311, [Class 82 (i)], is referred to.
