Abstract

In a method of obtaining porous metal articles of copper, tin and nickel, a mixture of bronze powder and nickel powder is sintered at a temperature between 900 DEG and 1120 DEG C., volatile porosity forming substances being added if desired. The mixture may contain from 5 to 95 per cent by weight of bronze and not more than 1 per cent each by weight of phosphorus, boron, magnesium, manganese and zinc. The bronze may contain from 2 to 15 per cent by weight of tin. In one example, a filter cone is made from a mixture of 50 per cent nickel powder and 50 per cent bronze powder containing 90 per cent copper and 10 per cent tin. The powders are between 100 and 200 mesh, are mixed for twelve hours, lightly pressed into a mould and heated at 1100 DEG C. in a non-oxidizing atmosphere. In another example, a filter disc is made from 70 per cent nickel powder and 30 per cent bronze powder, all between 200 and 300 mesh mixed together and with stearic acid. The mixture is poured into a mould 6 inches in diameter and 1/8 th inch deep and sintered at 1100 DEG C. in a non-oxidizing atmosphere. Specification 530,995 is referred to.
