For lighting / Code, composition, diameter
| Name | Code | Composition | Diameter(Diameter tolerance) | Application |
|---|
| Tungsten rod Class 1 | VWB1-[ ] | W99.96% or more | φ0.03-φ26(}1%) | Various electrical discharge lamp, |
| Tungsten rod Class2 | VWB2-[ ] | W99.96% or more | φ0.03-φ26(}3%) | electrode for electronic bulb, anchor, etc. |
[ ]: Finishing condition is classified into 4 types: (D) As drawn, (C) Chemical treatment, (E) Electrolytic polishing, and (G) Grinding.
For tungsten Class2: there are two types: (S) As stripped and (H) Heat treatment respectively.
Other materials: Pure tungsten (high purity material) and other materials are available according to the application. Please contact us for details.
For electronic parts: Because of its high modulus of elasticity, some tungsten rods are used as the probe pin for inspecting semiconductor chip. Please contact us for specifications and others.
Others: Secondary processes such as cutting grinding, bending, and brazing are available according to the application. Please contact us for details.
