Molybdenum Wire Description:
Product name: Molybdenum Wire
Standard: ASTM B387
Material: Mo >99.95%
Density: >10.2g/cc
Molybdenum Wire Application:
Molybdenum wire can withstand high temperatures and corrosion, it is used as heating material for high-temperature resistance furnaces, heating elements, automotive, aerospace, wire cutting machine; With good electrical conductivity, molybdenum wire also can be applied to electronic tube sockets, 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 and spray material.
Molybdenum Wire Specifications:
Our molybdenum wire is produced by stretching the Molybdenum rod to various diameter after the rod undergo the pass rolling and rotary forging to about 3mm. The Advantages of our molybdenum wire are good stability, good tensile strength, high precision cutting, and low elongation. Our factory can provide various of molybdenum wires with a diameter of 0.18~3.0mm, we can also provide custom products as per your requirements. We offer 2,000 to 3,000 kg of pure molybdenum wire products per month. Standard availability is described below. Other sizes and tolerances are available.

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 straightness increases, tensile strength decreases.
Out-of Roundness
Out-of-roundness of the 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
The 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
The 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.
