Boron carbide manufactured at Songshan Specialty Materials, Inc can meet GB2477-83、 FEPA、JIS standards for product quality.
　　Boron carbide is smelted from boric acid and powdered carbon in electric furnace under high temperature.Depending on hardness of 4950kgf/mm²,It is even harder than diamond and cubic boron nitride.Because of their high strength,low density, corrosion resistant,high temperature resistant,low thermal conductivity,high modulus of elasticity,it is ideal for a wide variety of applications.
