TA3
TA3 is industrial pure titanium. They have high mechanical properties, excellent stamping properties, and can be used for various forms of welding and welded joints. The strength can reach 90% of the strength of the base metal, and the cutting performance is good. Titanium tubes have high corrosion resistance to chlorides, sulfides and ammonia able. Titanium’s corrosion resistance in seawater is higher than aluminum alloys, stainless steel, and nickel-based alloys. Titanium is also highly resistant to water impact.
