Novel temperature-resistant wear-resistant copper alloy and application thereof

Abstract

The present invention relates to a novel temperature-resistant wear-resistant copper alloy and an application thereof, belongs to the technical field of non-ferrous metal materials and preparation methods thereof, and solves a technical problem of insufficient wear resistance and working stability of a copper screw nut in a high-temperature environment. A solution is as follows: a composition of the novel temperature-resistant wear-resistant copper alloy and mass percentages thereof are as follows: 35%-42% of zinc, 2%-4% of aluminum, 4%-7% of manganese, 0.4%-0.7% of nickel, 4%-7% of a silicon-chromium-iron alloy, and a balance being copper; the novel temperature-resistant wear-resistant copper alloy is used for preparing a copper alloy part that operates by relying on frictional force in a high-temperature environment, namely a copper screw nut, and a preparation process step of the copper screw nut is disclosed.
