The metal which is made of only titanium is called pure titanium.
And some additional metal is added, it is called alloyed titanium.
Alloyed titanium has wide range of characteristics.
There are 3 big groups in titanium alloy.

As explained before, titanium is change its structure at 885℃。
α alloy keeps the structure same as pure titanium lower than 885℃.
β alloy keeps the structure same as higher than 885℃。
And
α＋β alloy has the good characteristics of both α and β alloy.
They have wide range of splendid characteristics.
　
Titanium and titanium alloy has the wide range of characteristics such as,
Good bending, high strength, weldability and formability.
