Titanium aluminum flat target is an alloy sputtering target material used for vacuum coating. It obtains titanium aluminum alloy targets with different characteristics by adjusting the content of titanium and aluminum. Titanium aluminum alloy is a hard and brittle material with good wear resistance. It is coated with a layer of titanium aluminum intermetallic compound on the surface of ordinary cutting tools, which can effectively extend the service life of the tools. In addition, titanium aluminum flat target materials are widely used in fields such as tool and mold coatings, decorative coatings, large-area coatings, thin-film solar cells, data storage, optics, flat displays, and large-scale integrated circuits. This material plays an important role in multiple industrial fields due to its unique physical and chemical properties.
