Abstract
A hardened lead alloy for bearings contains 0,5-5,0 per cent of tin and 0,6-2,0 of calcium, the major portion of the latter being in the form of calcium lead crystals distributed through the body of the alloy. The alloy may also contain 0,02-0,1 per cent of aluminium and 0,1-1,0 of mercury. Instead of mercury or in addition to mercury in quantities of 0,1-0,25 per cent one of the following metals may be present in the percentages stated:-Silver 0,5-2,0, barium 0,02-0,1, strontium 0,02-0,5, copper 0,05-0,5, and manganese 0,05-0,5. In the preparation of an alloy, the lead is melted under a suitable flux and aluminium introduced preferably as an alloy containing 50 per cent of tin. The calcium is then introduced in metallic form or in the form of a lead alloy containing 5 per cent of calcium. If any of the auxiliary hardeners such as silver, are employed, they may be introduced either in metallic form or in the form of a tin alloy. The melt is then allowed to cool and the slag covering skimmed off or is allowed to solidify, and remelted to about 371 DEG C. and the mercury, if desired, and the rest of the tin added.
