Titanium alloys are alloys composed of titanium and other chemical components. These alloys have extremely high tensile strength and hardness (even at high temperatures). They are lightweight, have exceptional corrosion resistance, and can survive severe temperatures.

However, because to the high cost of both raw materials and processing, they are only used in military applications, airplanes, spacecraft, bicycles, medical devices, jewelry, highly stressed components like as connecting rods on costly sports vehicles, and some premium sports equipment and consumer electronics.

Although "commercially pure" titanium possesses acceptable mechanical qualities and has been used for orthopedic and dental implants, titanium is often alloyed with minor quantities of aluminum and vanadium, approximately 6% and 4% by weight, for most purposes. 

The solid solubility of this combination fluctuates substantially with temperature, allowing it to undergo precipitation strengthening. This heat treatment technique is performed after the alloy has been worked into its final shape but before it is used, making the manufacture of a high-strength product considerably easier.
