TA1-4 Pure Titanium

Update : 2026-02-25

TA1-4 Pure Titanium
TA1‑TA4 are a series of commercially pure titanium grades (equivalent to ASTM Grade 1 to 4) with excellent corrosion resistance, low density, and high strength‑to‑weight ratio. They offer good ductility, formability, and weldability, with strength gradually increasing from TA1 to TA4 while ductility decreases slightly. These alpha‑phase titanium materials deliver outstanding resistance to seawater, chlorides, and mild corrosive media. Widely used in aerospace, marine, chemical, and medical fields, they provide reliable performance for lightweight, corrosion‑resistant components.
