Titanium alloys are metals that contain a mixture of titanium and other chemical elements. For most applications it is alloyed with small amounts of aluminum and vanadium, typically 6% and 4% respectively, and for some its also alloyed with palladium. Such alloys have very high tensile strength and toughness, they are light in weight, have corrosion resistance and the ability to withstand high temperatures. The heat resistance enables a heat treatment process after the alloy has been worked into its final shape but before it is put to use, allowing much easier fabrication of a high-strength product.
