Basic Info

Model No.: SYWD-067

Product Description

  Product Description 0.18mm edm Molybdenum Wire   1. Description of molybdenum wire : Product name: Molybdenum Wire
Standard: ASTM B387
Material: Mo >99.95%
Density: >10.2g/cc   2. Application of molybdenum wire :      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.   3. Specifications of molybdenum wire : 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 with good stability, good tensile strength, high precision cutting and low elongation. Our factory can provide various of molybdenum wires with the diameter among 0.18~3.0mm, we can also provide custom products as your requirements. We offer 2,000 to 3,000 kg pure molybdenum wire products per month. Standard availability is described below. Other sizes and tolerances are available.

4. Dimensions and Tolerances of  molybdenum wire   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%.   5. Tensile Strength of  molybdenum wire   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.     6.Characteristic of cleaned Molybdenum wires:
