Description

Technical field [0001] The invention relates to an alloy and a preparation method thereof, in particular to a copper-chromium alloy and a preparation method thereof. Background technique [0002] Metal alloy materials have a wide range of applications, and copper alloys occupy a large proportion in the use of metal alloy materials. Possessing good tensile strength is the basic condition for the application of copper alloys in some key areas. For example, it has high tensile strength and can be used in some professional directions that have higher requirements for the tensile properties of metal alloys. The tensile strength of conventional copper alloy materials is low, usually only 400Mpa to 600Mpa. Due to the low tensile strength of conventional alloy materials, its application is limited to a certain extent. Summary of the invention [0003] The technical problem to be solved: the problem of low tensile strength of conventional copper alloys. [0004] Technical Solution: The pre...
