Ferroalloy production and consumption: ferroalloy electric furnace main production, high power consumption (combined average of about 5,000 per ton kwh) silicon carbide powder, need abundant and inexpensive power resources. France an early major producers of silicon carbide ferroalloy manufacturers, Norway became the largest exporter of iron alloy, it is based on local rich hydropower resources of the foundation.
