By controlling the forging process and supplementing with the hot isostatic pressing process when necessary, FANMETAL supply the pure tungsten rods and other forged products not only ensure high density, but also effectively control the grain size. High-density and fine-grained tungsten, molybdenum and alloy forged products have become a feature of FANMETAL products, which makes the products have obvious advantages in post-processing and effectively improves product life.

The density of the processed tungsten rod can reach 18.8~19.2 g/cm3. Since the billet is forged into a round billet, the deformation of each part is different, which makes the structure uneven. At this time, recrystallization annealing should be performed. The final minimum diameter of the swaging tungsten bar is about 3 mm. Qualified blanks are one of the keys to tungsten production. To make a good blank, you must first select qualified tungsten powder. The characteristics of the powder (average particle size, particle size distribution, chemical composition), mixing, forming and sintering processes have a direct impact on the composition, density and microstructure of the blank, and strongly affect the processing and use performance of the product.
