Abstract

506,964. Compositions containing metals. TOOL METAL MANUFACTURING CO., Ltd. June 21, 1938, No. 18485. Convention date, June 21, 1937. [Class 70] A composition for cutting tools comprises a sintered mixture of aluminium oxide and from 20 to 40 per cent of a metal such as iron, nickel or cobalt. The iron may contain 0À1 to 5 per cent of chromium, vanadium, titanium, cobalt or nickel. The composition may be of aluminium oxide and metal oxide, the latter being converted to the metal by sintering in a reducing atmosphere.
