All high -quality shank diameter 6 mm type trademark registration application
It is a product that is particular about selecting materials, unlike cheap ready -made products.
■ Carbide is the second hardest after diamond and about twice the weight of iron and stainless steel.
Made from tungsten and cobalt, tungsten cannot be made by melting like iron because of its high melting point. Therefore, it is manufactured by powdering and baking at a high temperature of 1,300 to 1,500 ° C. Use cobalt as a binding material at that time. The higher the amount of cobalt, the higher the anti -deterioration, but the hardness and wear resistance are lower.
■ The MUJUN contradiction series is made of 1,500 HV hardness and is made of a carbide material with a certain anti -deterioration.
■ Since its release, it has been well received by locksmiths, automobile shops, sheet metal shops, and metal factories nationwide.
