Tungsten Wire Mesh
Tungsten wire is made from doped powders, that is, powders in which
small quantities of potassium, silicon, and aluminum have been
incorporated. Their purpose is to influence the recrystallized
grain structure to reduce the creep rate at the high temperatures
of incandescent filaments. The powders are consolidated under high
pressure, sintered at high temperatures and worked by rolling and
swaging to heavy rod suitable for drawing.
Tungsten wire drawing is accomplished by coating the wire with a
graphite lubricant, heating to a red heat, and then drawing through
tungsten carbide or diamond dies. The process is sometimes referred
to as hot cold-working, which means that, while the wire is hot,
the temperature is still below the recrystallization range.
Accordingly, as the cross-sectional area is reduced, strength and
ductility increase. The as-drawn wire at finished size subsequently
may be cleaned, straightened, or annealed. Through various drawing
methods and annealing steps, We produces different physical
characteristics in wire of a given size. Our control of each
manufacturing step from tungsten ore to finished wire assures
reliability and reproducibility.
