Tungsten Contacts Processing Requirements

With the development of science and technology and industry, people are increasing their demand for tungsten contacts and they are stricter with tungsten contacts processing requirements, whose processing requirements of the tungsten contacts as follows:

Hardness should be higher;

Impact toughness should be better;

Rod surface should be smooth;

Thermal expansion coefficient should be smaller;

Arc-resistant performance should be better and stable;

Rod is without scratches and cracks;

Section crystal grain fibers should be short;

Section crystal grain should be uniform and fine;

Roundness, concentricity and flatness should be better;

The vapor pressure should be lower; the evaporation rate should be slower;

To meet people’s demand for tungsten contacts, the technicist of the manufacturers has done a lot of research on tungsten contacts’ physical and mechanical properties. In the production process, they comprehensively analyze the factor of tungsten contacts, such as, brittle fracture, splitting, uniform section crystal grain size, and other reasons. And they target to take a series of measures to avoid the above phenomenon.
