Tungsten Carbide Measuring Ball
Description
The surface of tungsten carbide measuring ball is finished, and the finish grade is better than ▽10, roundness tolerances with ±Ø0.001mm~0.0035mm, the general sizes are Ø2.5mm, Ø3mmm, Ø5mm and Ø10mm. The balls are used as measuring's ideal choose as the stability properties of tungsten carbide.
Application
Tungsten carbide measuring ball as hardness measuring head, could reach the national standard, which could expand Brinell hardness measurement range.
