This alloy is commonly referred to as a commercially pure titanium. Widely used in industrial applications. All automatic weld processes can be used. Can be used in seawater, heat exchanges, piping systems. Titanium is a reactive metal that is sensitive to embrittlement by oxygen, nitrogen and hydrogen at temperat cleanliness. Can be fusion welded to Zirconium, Tantalum, Nobium and Vanadium. Should not be fusion welded to Copper, Iron, Nickel, and Aluminum, as it will produce extremely brittle welds
