Good quality Solid Tungsten Cube - W1 WAL Tungsten Wire – Fotma
Good quality Solid Tungsten Cube - W1 WAL Tungsten Wire – Fotma Detail:
We produce two types of tungsten wire – Pure tungsten wire and WAL (K-Al-Si doped) tungsten wire.
Pure tungsten wire is produced typically for re-straightening into rod products and for applications where there is a low alkali content requirement.
WAL tungsten wire which has been doped with trace amounts of potassium has an elongated interlocking grain structure with non-sag properties after re-crystallization. WAL tungsten wire is produced in sizes from less than 0.02mm up to 6.5mm in diameter and is used largely for lamp filament and wire filament applications.
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.
