With good performance in strength, anti-corrosion and thermal resistance, CNC machining titanium alloy parts are used widely in various fields. After realizing the importance of titanium alloy materials, many countries devote to the research and development and apply them in practice. Thermal resistance, strength, malleability, toughness, formability, weldability, anti-corrosion and bio-compatibility, all of these make titanium alloy become the trump in the field.
