In its pure form, molybdenum is a silvery grey metal with a Mohs hardness of 5.5. It has a melting point of 2,623 °C ; of the naturally occurring elements, only tantalum, osmium, rhenium, tungsten, and carbon have higher melting points. Weak oxidation of molybdenum starts at 300 °C .
Molybdenum Rods and Wires. Pure moly wire and rods are mainly used for electrical lighting source parts, high temperature heating elements, and wire for wire cutting. Molybdenum Bars. Bars are used as blanks for molybdenum wire, rods, flats, etc., and additives to precision alloys.
Molybdenum and molybdenum alloys can be machined by all of the common metal machining processes. No special equipment or procedures are required to produce parts with accurate dimensions with excellent ﬁnishes. Moly bdenum may be machined to achieve simple parts, very complex parts/shapes, and very small intricate parts. TOOLS
The choice between high speed steel and sintered carbide depends largely on production quantities. In either case, tool life is shorter than would be expected with steel because molybdenum is considerably more abrasive than steel at the same hardness, and molybdenum has a tendency to chip while being machined.
Characteristics Physical properties. In its pure form, molybdenum is a silvery grey metal with a Mohs hardness of 5.5 and a standard atomic weight of 95.95 g/mol. It has a melting point of 2,623 °C ; of the naturally occurring elements, only tantalum, osmium, rhenium, tungsten, and carbon have higher melting points.gray metallic /məˈlɪbdənəm/ 42
540 Executive Drive Willowbrook, IL 60527 [email protected] with a feed of 0.003 inches per revolution. Molybdenum has a tendency to chip, so depth during threading should not be more than 50% 60%. Molybdenum can be rolled threaded, but this method is slow, and the preferred, faster methods consist of turning or chasing.
