Free Silicon Carbon Alloy/High Carbon Silicon/High Carbon Ferro Silicon

High Carbon Ferro Silicon is a by-product comes from silicon metal plant. It deposits on the bottom of the melting furnace, and when it accumulates to a certain amount, it will be taked out through explosion. Silicon Carbon Alloy has to be cleaned out in three months to six months, so the output is limited. We collect and select it from Silicon metal factories in China.
