Titanium Grade 1, Titanium Grade 2, and Titanium Grade 3 are industrial pure titanium. They can be welded in various forms and have good welding performance. The welded joint can reach 90% of the strength of the base metal. Easy to cut with saws and grinders, and has good machining properties. It has excellent corrosion resistance and is used for parts with a temperature below 350℃ and small stress and parts stamped into various complex shapes. Such as thermal power station condensers; marine seawater corroded piping systems, valves, pumps; chemical heat exchangers, pump bodies, distillation towers; seawater desalination systems, platinum-coated anodes; aircraft frames, skins, engine parts, beams, etc.

Ti-6AL-4V is a titanium alloy. Titanium alloy is an alloy based on titanium and added with other alloying elements. Titanium alloy has the advantages of low density, high specific strength, good corrosion resistance, and good process performance. It is an ideal structural material for aerospace engineering.

TC4 has poor stamping properties and good thermoplasticity. Various forms of welding can be performed, and the strength of the welded joint can reach 90% of the strength of the base metal. The machining performance is still good, requiring the use of carbide tools, large cutting speed, slow speed, and sufficient cooling. Good corrosion resistance and good thermal stability. It is one of the most widely used titanium alloys and is used for parts that work under 400℃ for a long time.
