1. Introduction to TA3/Gr3 materials
TA3 is industrial pure titanium. They have high mechanical properties, excellent stamping properties, and can be welded in various forms. The strength of the welded joint can reach 90% of the metal strength of the matrix, and have good cutting performance. Titanium tubes have high corrosion resistance to chloride, sulfide and ammonia. Titanium has higher corrosion resistance in seawater than aluminum alloys, stainless steel, and nickel-based alloys. Titanium has strong water impact resistance.

5. Six major characteristics of TA3/Gr3
1. High strength: Titanium has better strength/density ratio than other metals, and can be made of titanium to make components with high strength, good rigidity and light weight. Titanium is used in aircraft engines, frames, skins, fasteners and landing gear.
2. Anti-corrosion: Compared with stainless steel, titanium alloy has better corrosion effect in humid air and seawater, and titanium has great resistance to pit corrosion, acid corrosion and stress corrosion. Titanium resists corrosion of alkali, chloride, chlorinated organic matter, sulfuric acid, nitric acid.
3. High temperature resistance: The application temperature of titanium is higher than that of aluminum alloy. Titanium can work for a long time at 450-500℃.
4. Low temperature resistance: When working at low temperature or ultra-low temperature conditions, titanium alloys still have their mechanical properties. Titanium alloys with low temperature resistance and extremely low gaps still have good ductility, so titanium alloys are a good low temperature structural material.
5. Environmentally friendly metals: Titanium has lower thermal conductivity than carbon steel or copper, but titanium has very good corrosion resistance. Therefore, the thickness of titanium can be greatly reduced, and the heat exchange mode is dropwise condensation between titanium and steam. This mode reduces heat transfer resistance and there is no scaling on the titanium surface, thus making the titanium more thermal conductivity.
6. Good thermal conductivity: Titanium is a non-magnetic metal and cannot be magnetized in large magnetic fields. Moreover, titanium is non-toxic and compatible with blood, so titanium has been used in the medical field.
