Application

Molybdenum wire can withstand high temperature and corrosion, it is used as heating materials of high-temperature resistance furnace, heating elements, automotive, aerospace, wire cutting machine; With good electrical conductivity, molybdenum wire also can be applied to electronic tube socket, stent filament incandescent lamp, halogen lamps, discharge tube sealing material, lead-wire, tungsten filament with the mandrel, the grid. There are some other common uses for molybdenum wire such as cathode, spray material.

Dimensions and Tolerances

Wire diameters are generally expressed in terms of inches or mils (thousandths of an inch). For thin wires from 0.001 inches up to 0.020 inches, the size of the wire is measured by weight per unit length. That is, the weight expressed in mg of a 200mm length of wire.

The standard diameter tolerance is ±3% of the weight measurement. For mandrel applications, the tolerance is normally ±1%.

Tensile Strength

Tensile strength for molybdenum wire is usually expressed in grams per milligram weight of a 200 millimeter length (or) g/mg/200mm. The normal range of values is 40 to 60 grams. In general, as tensile strength increases, wire straightness decreases.

Straightness

The measure of the straightness of a metal wire is obtained by cutting a ten inch long piece of wire and allowing it to lie on a flat clean surface. The maximum deviation from a straight line along its length is the quantitative measure of its straightness. In general, as the degree of the straightness increases, tensile strength decreases.

Out of Roundness

Out of roundness of wire does not exceed 4% of the wire diameter. It is measured as follows:

Out of Roundness = (Max Diameter ¨C Min Diameter) / Max Diameter x 100

Quality and Finish

Wire is free of scratches, kinks and distortions insofar as they are harmful to the intended use of the product. Surface finish is supplied in the black, as drawn condition, where drawing lubricants and oxides are retained on the surface, or in the cleaned condition by firing in hydrogen or electrochemical etching

Spooling

Wire is spooled on clean, defect free spools. For very large diameters, wire is self coiled. Spools are level filled without piling near flanges. The outer end of the wire is properly marked and attached securely to the spool or self coil.
