Mechanical properties:
Many factors, including microstructure, impurity content, other alloying materials, and heat treatment (annealing conditions), affect the mechanical properties of tungsten. By providing pure tungsten and various tungsten alloys, TLWM can meet the different needs of various users.
Chemical properties:
Tungsten has good corrosion resistance at humidity below 60%. At 250°C, tungsten is oxidized in oxygen; however, molten glass, nitrogen, inert gases, molten metals and ceramic oxides have little effect on tungsten.
