Electrical discharge machining of silicon carbide using brass electrode

Siliconized silicon carbide, SiSiC is classified as semiconductor and characterized as high hardness, high thermal conductivity, low thermal expansion and typically low porosity materials. SiSiC normally used under high temperature condition such as for heat exchangers, burners, disc brakes and mech...
