Tungsten Points Processing Requirements

People’s demand for tungsten points is increasing sharply with the development of automotive industry. Besides, they have strict processing requirements of tungsten points, whose processing requirements as described below:
High hardness;
Good impact toughness;
Smooth rod surface;
Small thermal expansion coefficient;
Excellent and stable arc-resistant performance;
There are no scratches and cracks in rod;
Section crystals fibers should be short;
With uniform and fine section crystals;
Owning better roundness, concentricity and flatness;
Having lower vapor pressure;
Possessing slower evaporation rate;
In order to satisfy people’s demand for tungsten points, the technicians of manufacturers have done lots of study on tungsten points’ physical and mechanical performance. In the producing process, they analyze the defects of tungsten points comprehensively, such as, splitting, brittle fracture, uniform section crystals size and others. What’s more, they have taken a series of measures to avoid the aforementioned problems.
