Main Factors on Quality of Tungsten Points (1)

1. Metallurgical defect of tungsten blanks can have an effect on the quality of tungsten points

Metallurgical defects of tungsten blanks refer mainly to:
In the smelting process, the inside part of tungsten blanks form defects, such as, slag inclusions, pores and so on. What’s more, some of these defects are difficult to preclude even in pressing process. For example, in the crystal boundary, there is the distribution of Ni, Fe and other impurities or compounds. The combination of grain surface is damaged due to these impurities, pores and other defects. So its metal bases are not continuous, it will result in the generation of cracks or tears of tungsten blanks in the process, and eventually lead to its final product --- tungsten points’ split and brittleness.
