Titanium
thyssenkrupp Aerospace stocks titanium in both commercially pure and alloyed forms.
The principal characteristics of commercially pure titanium include an excellent resistance to corrosion by a wide range of natural and artificial environments, together with a useful strength-to-weight ratio.
Commercially pure titanium can be readily forged, formed, or welded by most of the processes conventionally used for stainless steel, which it resembles in many mechanical and chemical respects.
The most common and widely-used titanium alloy in the aerospace industry is 6Al-4V, which is used for applications that require higher strength and corrosion resistance.
