Scope:
This specification covers two grades of molybdenum wire less than
0.050 in. (1.27 mm) in diameter
and one grade of molybdenum rod 1.00 in. (25.4 mm) or less in diameter
as follows:
Grade 1 - Commercially pure molybdenum wire suitable for leads, hooks,
supports, heaters, and
metal-to-glass seals.
Grade 2 - Commercially pure molybdenum wire suitable for mandrel
either black or cleaned.
Grade 3 - Commercially pure molybdenum rod suitable for leads, hooks,
supports, and metal-to-glass
seals.
The term wire applies to all spooled or coiled material and 0.050 in.
(1.3 mm) or less in diameter
and to short cut lengths 0.020 in. (0.51 mm) or less in diameter.
The term rod applies to all material over 0.020 in. (0.51 mm) in
diameter, supplied in straight
lengths.
The values stated in inch-pound units are to be regarded as the
standard. The metric equivalents of
inch-pound units may be approximate, except for the size of the wire
expressed in milligrams per
200 mm.
This standard does not purport to address all of the safety concerns,
if any, associated with its
