Titanium aluminum alloy

Titanium aluminum is a silver-white metal, it has many excellent properties. Titanium has a density of 4.54g / cm3, 43% lighter than steel, slightly heavier than the prestigious light-metal magnesium. Its mechanical strength is about the same as that of steel, twice as large as aluminum and five times as large as magnesium. Titanium high temperature, the melting point of 1942K, higher than gold high 1000K, 500K higher than steel.

Titanium aluminum alloy in the vacuum coating industry is also widely used, can be made of a certain percentage of the alloy target for magnetron sputtering coating raw materials. Titanium aluminum alloy vacuum deposition target in a variety of compositional ratios, commonly used titanium aluminum atomic ratio (at%): 90:10, 80:20, 70:30, 50:50, 30:30, 20: 80,10: 90. Titanium-aluminum alloy can be produced by vacuum casting when the titanium atom content is greater than or equal to 50%. When the content of aluminum is relatively decreased, the titanium content can only be produced by powder metallurgy to achieve the target. Titanium aluminum alloy with a titanium atom of 80% or more can also be forged and rolled.
