Description:
1.Tungsten wire, also known as wolfram wire.
2.It normally has two different surfaces as black surface and cleaned surface.
3.Covered with graphite, tungsten wire are regularly black.(black surface)
4. If graphite being removed, they appear with metallic luster.(cleaned surface)
5.We can offer spool and straight type, whose diameters are all above 0.01 mm.
6.According to various impurity contents, tungsten wires can be subdivided into W1, W2, WAL1 and WAL2 grades.
