Domestic Production of Non-magnetic Hard Alloy

Researcher Hong Myong Son at Faculty of Materials Science and Technology and his research group succeeded in producing non-magnetic hard alloy which contains no cobalt with domestically available raw materials. This kind of alloy is used as the basic material of molding tools and is urgently needed in the various sectors of the national economy.

The hardness of this alloy is more than HRA 91, the bending strength more than 1.8GPa and the saturation magnetization strength less than 3Gs.
