Titanium Grades
Titanium grades are Titanium Alloys are generally divided into
three groups (Alpha, Alpha-Beta and Beta).
The Alpha group contain most importantly aluminum and tin. They can
also contain molybdenum, zirconium, nitrogen, vanadium, columbium,
tantalum, and silicon. Alpha alloys are not suitable for heat
treatment. Alpha alloys are used for aircraft parts
and cryogenic equipment.
The Alpha-Beta group can be strengthened by heat treatment. The alloys
are used in aircraft and aircraft turbine parts, chemical processing
equipment, marine hardware.
The Beta Alloys have good hardenability. Beta alloys are slightly more
dense than other titanium alloys, having densities ranging from 4800 to
5050 kg/m
3. They are the least creep
resistant alloys, they are weldable, and can have yield strengths up to
1345 x 10
6 Pa.(Solution treated and age
hardened) Beta alloys are the smallest
group. They are used for heavier duty purposes on aircraft.
