1. Introduction to TA3/Gr3 materials
TA3 is commercially pure titanium with high mechanical strength, excellent stamping performance and versatile weldability. Weld joints can reach 90% of base metal strength, and the material delivers good machinability. Titanium tubing features outstanding resistance to chloride, sulfide and ammonia corrosion. In seawater environments, titanium outperforms aluminum alloy, stainless steel and nickel-based alloys, with strong erosion resistance against water flow impact.

5. Six major characteristics of TA3/Gr3
1. High specific strength: Superior strength-to-density ratio compared to other metals, lightweight high-rigidity structural parts widely used in aircraft engines, frames, skins, fasteners and landing gear.
2. Excellent corrosion resistance: Outperforms stainless steel in humid air and seawater, resistant to pitting, acid and stress corrosion, stable against alkalis, chlorides, chlorinated organics, sulfuric acid and nitric acid.
3. High temperature resistance: Service temperature higher than aluminum alloy, stable long-term service at 450-500℃.
4. Cryogenic performance: Retains complete mechanical properties under ultra-low temperature; low-interstitial titanium alloys maintain good ductility, ideal cryogenic structural material.
5. High heat exchange efficiency: Lower thermal conductivity than carbon steel and copper, outstanding corrosion resistance allows thinner wall design. Dropwise condensation forms on titanium surface without scaling, reducing thermal resistance and improving heat transfer efficiency.
6. Non-magnetic & biocompatible: Cannot be magnetized under strong magnetic field, non-toxic and blood-compatible, widely applied in medical equipment.
