High Purity Ground Finish Tungsten Rod (HW91, HW71) /Tungsten Bar

Basic Info

Model No.:  HW91, HW71

Product Description

Model NO.: HW91, HW71 Standard: GB, DIN Alloy: Non-alloy Type: Tungsten Bars OEM: Acceptable Density: 19.20 Transport Package: in Wooden/Carton Cases Origin: Hunan, China Application: Aviation, Electronics, Industrial, Medical Purity: >99.95% Shape: Round Surface Condition: Machined,Black,Ground,Polished Tolerance: +/-0.05mm Trademark: ZZKD Specification: Diameter: 0.05-1.17inch HS Code: 810199900 Tungsten has the highest melting point (3410°C) and the lowest vapour pressure among all the metals, which makes it a preferred candidate for use as a high performance material in a variety of high temperature products and processes. 

Mechanical Properties:
A lot of factors such as microstructure, impurity contents in the tungsten, other alloying elements and heat treatment (for example annealing conditions) inflence the machanical properties of tungsten. By offering various tungsten alloys, TLWM could satisfy the specific needs from customers.

Chemical Properties:
Tungsten is resistant to corrosion when the humidity is below 60%. However, it must be protected at elevated temperatures. Tungsten can oxidize in the presence of oxidizing gases at temperatures above 250°C. Despite this vulnerability, Molten glass, nitrogen, inert gases, molten metals and ceramic oxides only slightly affect it.

Suitable for producing ion implantation parts
For producing electric light source parts,components of electric vacuum
For producing W-boats,heat shield and heat bodies in high temperature furnace
Used for tungsten sputtering target
