Description

technical field [0001] The invention belongs to the field of alloys. It relates to an alloy material and a preparation method thereof, in particular to a copper-titanium alloy material and a preparation method thereof. Background technique [0002] Two or more metal elements or metal materials with metal properties formed by adding other non-metal elements based on metals through smelting, sintering, vapor deposition, etc. are called alloys. The formation of alloys often improves the properties of elemental substances, for example, steel is stronger than its main constituent element iron. The physical properties of an alloy, such as density, electrical conductivity, and thermal conductivity may have a great relationship with the constituent elements of the alloy. [0003] Pure copper is fuchsia, has excellent thermal conductivity and electrical conductivity, and its electrical conductivity ranks second only to silver. Copper has excellent chemical stability and corrosion ...
