This specification covers powder metallurgy (PM) structural
components fabricated from commercially pure (CP) titanium powder
mixed with master alloy powder and elemental powders in appropriate
quantity to yield combined material chemical compositions
comparable to ingot metallurgy (I/M) alloys Titanium 6A1-4V and
This specification covers the following materials:
Two types depending on alloy composition as detailed in Table
Type I is comparable to I/M Ti-6A1-4V.
Type II is comparable to I/M Ti-6A1-6V-2Sn.
Two grades of each type that result from the specific titanium
powder used are as follows:
Grade 1 is made from sponge fines with residual levels of
chlorine and sodium.
Grade 2 is made from hydride/dehydride (HDH) or other process
titanium with significantly lower chlorine and sodium content.
Two classes as a function of density (see Table 2) are as
Class A density ratio is 94 % minimum.
Class B density ratio is 99 % minimum.
(Warning—CP titanium powder may be pyrophoric; its
use may involve an explosion hazard.)
The values stated in inch-pound units are to be regarded as the
standard. The SI units given in parentheses are for information
