We produces two types of tungsten wire - Pure and WAL (K-Al-Si doped).
Pure tungsten wire is produced in sizes above. 020 inches in diameter. Typical usage is for restraightening into rod products and for applications where there is a low alkali content requirement.
WAL is wire which has been doped with trace amounts of potassium, causing the wire to exhibit an elongated interlocking grain structure with non-sag properties after recrystallization. WAL 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.
Dimensions and Tolerances
Wire diameters are generally expressed in terms of mm(or inches). For thin wires from 0.02mm up to 0.5mm in diameter, the diameter of the wire is measured by weight per unit length. That is, the weight expressed in mg of a 200 mm length of wire.
The standard diameter tolerance is 3% of the weight measurement. Closer tolerances are available, depending upon the application for the wire product.
For thicker wires from 0.5mm up to 6.5mm in diameter, the mm measurements are used. The tolerances are expressed as a percentage of the diameter. Standard tolerance is 1.5%.
