polished surface tungsten capillary tungsten pipe support pillar
1. high purity as ≥99.95%
2. high density as sintering bar or forged bar
3. excellent mechanical properties
4. can bear high temperature
According to the diamter, we have different production way for tungsten bar.
1. Small diameter like Ø5mm produced by swaging/spining,
2. if the diameter is up to 15mm, we will forge the rod after sintering, it will have high density.
3. When the diameter is as big as 150mm, we can only sinter it because of the big dimension. Density would be above 18.5g/cm3
All tungsten rod surface could be black, lathe-polishing and grinding according to customer’s requirments.
Tungsten rods are mainly used as heater, support pillar, feeder and fastener in vacuum or reducing atmosphere high temperature furnace. Also as light source in lighting industry, electrode in glass melting, and welding equipments.
tungsten powder---isostatic pressing--high temperature sintering---tungsten rod ingot---swaging for thin diameter---black surface---polish to bright surface
For the tungsten Rod, following is the normal tungsten rod dimension form. For any special dimension, call us please.
