[0002] Titanium alloy tubes are tubes made of titanium alloys. Titanium alloys can be divided into three categories according to their organization: titanium with aluminum and tin elements added; titanium with aluminum, chromium, molybdenum, vanadium and other alloy elements added; titanium with aluminum and vanadium and other elements added. 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 strength of the base metal, and the cutting performance is good.
