Rust-preventing aluminum alloy

Abstract

The invention discloses a rust-proof aluminum alloy, which not only comprises 51 to 97.95 weight percent of aluminum, 0.01 to 2 weight percent of manganese, 0.01 to 2 weight percent of magnesium, and 0.01 to 3 weight percent of copper, but also comprises 1 to 19 weight percent of chromium, 0.01 to 9 weight percent of nickel, 0.01 to 4 weight percent of silicon, and 1 to 47.95 weight percent of aluminum oxide. The aluminum oxide forms a corundum-like substance in an aluminum alloy body to obviously improve the overall corrosion resistance and wear resistance of the aluminum alloy.

Description

technical field [0001] The invention relates to a rust-proof aluminum alloy, in particular to a rust-proof aluminum alloy with improved product strength and wear resistance. Background technique [0002] Existing antirust aluminum alloys have low hardness and are easily worn. In highly corrosive environments and under high pressure, it is easily corroded. [0003] Some try to add a large amount of silicon to the alloy, which can easily make the alloy brittle. [0004] Some try to add a large amount of nickel to the alloy, but this solution is uneconomical due to the high cost of nickel. [0005] Some try to add a large amount of iron to the alloy. Iron is a harmful substance in aluminum alloys and has a negative effect on the mechanical properties of aluminum alloys, so its use should be avoided. Contents of the invention [0006] The object of the present invention is to solve the above problems and provide a rust-proof aluminum alloy with improved product strength an...
