Factors on Tungsten Copper Points - Tungsten Powder Particle Size, Applications, Current Properties

Factors on tungsten copper points also include tungsten powder particle size, applications, current properties and so on. The detail can be seen as following.
3. Tungsten powder particle size. The anti-arc erosion property of tungsten copper points is not so well if thicker/thinner tungsten powders are used for the preparation of points’ material. However, if fine powder and coarse powder are mixed, at a proper proportion, then tungsten copper points’ properties will be relatively better. The Do’s and Don’ts: According to the components of points’ materials, the mixing ratio of powder is different.
4. Applications. There are experimental results showing that points with different components have their own optimal application situations for different applications. For example, the property of points materials’ anti-arc erosion is best when they are applied in air or a vacuum switch, its ratio is tungsten (90): copper (10).
5. Current performance. Points’ on and off process would bring about different transient performances when the current with different properties; but its value will maintain constant after being determined.
6. Breaking speed of points and early pressure.
