This invention relates to a method for identifying the magnetic properties of a mixture of
tungsten carbide powder and
cobalt powder. The method includes the following steps: (1) sampling the mixture of
tungsten carbide powder and
cobalt powder and sealing and storing the sample; (2) preparing the sealed sample into an identification compact, storing the compact in a fixed environment until the
expiration date, then placing it in a
graphite boat and
sintering it together with a large batch of products; (3) testing the magnetic properties of the sintered identification compact. The identification method simulates the actual
production cycle to the greatest extent possible. The
graphite boat isolates the sample from atmospheric influences without causing carbon buildup, and the identification results can reliably guide large-scale production.
