Beta-titanium

Beta-titanium

Beta titanium alloys exhibit the BCC allotropic form of titanium (called beta).

Elements in this alloy are titanium, molybdenum, vanadium, columbium, tantalum, manganese, iron, chromium, cobalt, nickel and copper.

This alloy is nowadays largely utilized in the orthodontic field.

Beta titanium alloys have a strength/modulus of elasticity ratios almost twice those of 18-8 austenitic stainless steel, larger elastic deflections in springs, and reduced force per unit displacement 2.2 times below those of stainless steel appliances.The titanium alloys have good formability and can be easily welded.
