Tungsten wire material: w1,w2,w-r Wire Gauge:0.05-2.0mm density: 19.3g/cm3 Surface: black / bright

Tungsten wire 

 

Tungsten wire is supplied in 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.

Tungsten wire is spooled on clean, defect free spools. For very large diameters, Tungsten 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.

Direction for Use

1. Aquadag layer on the surface of the Tungsten wire should be removed before using. The Tungsten wire is not suitable for contacting with iron, nickel, carbon, when the temperature is above 1000 centigrade. The Tungsten wire should be preserved in dry room, in which the relative humidity is never above 65%, and keeping away from acid or alkali atmosphere.2. Cleaned tungsten wire should be preserved in dry vessels.
