Commercially Pure
Titanium
Titanium Grade 1
The softest, best ductility, good formability, corrosion resistance, and
high impact toughness.
Titanium Grade 2
Slightly stronger than Grade 1, sharing similar characteristics, but
slightly stronger.
Titanium Grade 3
The strength is higher than the first two grades, the ductility is
equivalent, and the formability is slightly reduced.
Titanium Grade 4
The strongest of the four grades, corrosion resistant, and good in
forming and welding properties.
Commercially pure titanium contains a minimum of 99% pure titanium.
