Close Analogs: A wide range of Ti alloys are listed in MatWeb. Titanium Grades 1,2,3,4,7,11,and 12 are all considered unalloyed. This listing is for 'pure' titanium.

Component    Wt. % Ti 100

Material Notes:
This listing is for 'pure' titanium. Although unalloyed titanium is not very useful for structural applications, titanium alloys are highly praised for their use in aerospace, high-temperature and biomedical applications. Titanium is difficult to machine or weld, but has significant advantages over traditional metals. For medical implants, titanium is considered one of the most biocompatible materials available, especially where direct contact to tissue or bone is required (i.e. endosseuos dental implants or porous uncemented orthopedic implants). See the individual titanium alloy datasheets for specific applications.
