polished tungsten rod high purity tungsten bar
For the tungsten Rod, following is the normal tungsten rod dimension form. For any special dimension, call us please.
| item | surface | diameter/mm | length/mm | purity | density(g/cm³) | producing methord |
| Dia | tolerance | L | tolerance |
| tungsten rod | grind | ≥3-25 | ±0.05 | ＜5000 | ±2 | ≥99.95% | ≥19.1 | swaging |
| ＞25-150 | ±0.1-0.2 | ＜2000 | ±2 | ≥99.95% | ≥18.8 | forging |
| ＞150 | ±0.5 | ＜800 | ±2 | ≥99.95% | ≥18.5 | sintering |
| black | ≥3-25 | ±2 | ＜5000 | ±2 | ≥99.95% | ≥19.1 | swaging |
| ＞25-150 | ±3 | ＜2000 | ±2 | ≥99.95% | ≥18.8 | forging |
| ＞150 | ±5 | ＜800 | ±2 | ≥99.95% | ≥18.5 | sintering |
We could make the tungsten rod with big length.
Thanks to the high melting point, high density (above 18.8g/cm3), high purity (above 99.95%) characteristics, tungsten rod is widly applied in making crucible for sapphire growth furnace, electrode for rare earth high-temperature furnace, heating parts for high temperature furnance, connecting parts and supporting stick.
According to the diamter, we have different production way for tungsten bar.
Small diameter like Ø5mm produced by swaging/spining,
if the diameter is up to 15mm, we will forge the rod after sintering, it will have high density.
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.
As the manufacturer, firstly, we have very good quality control system, the products will be inspected by each step including the surface, the dimension, crack, or other inspection item as cumtomer requires.
Secondly, as a factory, our price has obvious advantages. We'd like to make our customer purchase good quality products with good price. It's a win-win business.
What's more, we have full after sales service. In case there is a quality problem, we are responsible. And we will do our best to solve the problem to make our customer satisfied.
