Abstract
The present invention relates to a hard and wear-resisting probe and manufacturing method thereof, and particularly relates to a hard and wear-resisting probe comprising tungsten steel (WC) and manufacturing method thereof. This hard and wear-resisting probe is substantially made of a tungsten steel with high hardness and wear resistance so that the probe is difficult to be worn and the lifetime of the probe is longer. Furthermore, the frequencies for changing the probe and the cost of testing are reduced, and the testing efficiency can be improved.
