TC4 titanium alloy machining parts

[ Supply status ]
Rough workblank, finish milling and finishing, mirror polishing finished products, surface deburring, acid pickling and passivation without oxidation.

[ Processing Technology ]

TC4 titanium rod/titanium plate/forging blank blanking → numerical control multi-shaft milling/turning/drilling and tapping → forging and reshaping/special argon arc welding for titanium alloy → deburring and cleaning → surface treatment → size verification+NDT.

[ Material Performance ]

The tensile strength of TC4 is much higher than that of TA2 pure titanium, which is resistant to impact and alternating fatigue, and the mechanical property is stable under long-term high temperature condition of 400 ℃; The passive film on the surface can resist seawater, salt mist and weak acid corrosion and is not easy to be pitted; Low density, 40% less weight than steel members; No magnetism, no interference with nuclear magnetic and vacuum sensing equipment; Medical grade TC4 ELI is biocompatible and can be used for human load-bearing implants.

[ Process structure ]

Special titanium alloy cutting process is adopted to reduce the machining stress and make the finished product not easy to deform; The grain of forging raw material is refined through multi-directional upsetting, the internal structure is dense, and the bearing capacity is stronger; Complex curved surface and porous special-shaped parts are integrally formed through five-axis machining to reduce splicing welds; High-purity argon protection is adopted for welding, and the weld strength is close to the base metal; Full size inspection and ultrasonic flaw detection of finished products, and elimination of internal microcracks and sand holes.
