Molybdenum Wires

Molybdenum wires

Molybdenum wires (Moly wires) can be grouped into black and white molybdenum wires or spray and wire cutting molybdenum wires.

Moly wire is used as hot cathode or gate in electron tube, sealing parts of glass and ceramics, electronic-vacuum and electric light source parts, and high temperature heaters. It can be also employed to roll molybdenum foil and remake small specification molybdenum wires.

Physical properties

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 (4, 753 °F); of the naturally occurring elements, only tantalum, osmium, rhenium, tungsten, and carbon have higher melting points. Weak oxidation of molybdenum starts at 300 °C (572 °F). It has one of the lowest coefficients of thermal expansion among commercially used metals. The tensile strength of molybdenum wires increases about 3 times, from about 10 to 30 GPa, when their diameter decreases from ~50–100 nm to 10 nm.
