High hardness tungsten alloy pin gauge is round rod made of tungsten alloy material with high hardness and specific size. It has high hardenability, high hardness, high wear resistance and strong contact fatigue strength. It is suitable for meso-machining in mechatronic processing. The measurement of the pitch and internal thread diameter is especially suitable for the measurement of the bending groove width and the die size. It is suitable for the measurement of aperture, hole pitch and internal thread diameter…
