TC4 Titanium punching poor, thermoplastic good. titanium plate Can be various forms of welding, weld joint strength Scientology metal strength 90%. Mechanical processing performance is still good, need to use carbide cutting tools, large amount passes, slow, sufficient cooling. Good corrosion resistance, good titanium wire thermal stability. TC4 Titanium is one of the most widely used titanium alloy. Do parts of the following 400 ℃ long-term work.
