Abrasion-resistant aluminum alloy

Abstract

A wear-resistant aluminum alloy belongs to the technical field of alloys. The wear-resistant aluminum alloy of the present invention is composed of the following materials in parts by weight: 1-6 parts of magnesium, 1-3 parts of silicon, 1-3 parts of iron, 1-3 parts of nodular cast iron, 0.1-0.6 parts of titanium, 1-3 parts of nickel-chromium alloy 5 parts, 0.1-1 parts of zinc, 0.1-1.5 parts of manganese, 1-4 parts of copper, 0.1-1 parts of boron, 0.1-0.5 parts of vanadium, 0.1-1 parts of cobalt, 0.1-1 parts of cerium, 0.1-0.5 parts of ytterbium , 1-3 parts of nickel, 1-2 parts of strontium, 0.1-1 part of chromium, and 100 parts of aluminum. The invention improves the strength of the aluminum alloy, has good manufacturing performance and mechanical performance, and enhances the wear resistance and corrosion resistance of the aluminum alloy.

Description

technical field [0001] The invention relates to a wear-resistant aluminum alloy and belongs to the technical field of alloys. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for welded structural parts of aluminum alloy is increasing day by day, so that the research on weldability of aluminum alloy is also in-depth. Aluminum alloy is currently the most widely used alloy. [0003] Aluminum alloy has low density, but relatively high strength, which is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. . Some alum...
