Dug this out (so-to-speak)
"Ferronickel and Nickel Pig Iron (NPI) are two alternatives to nickel metal. NPI typically contains around 4 to 10 wt% nickel. Its high amount of carbon (>3 wt%), silicon (>3 wt%) and manganese (>1 wt%) mean that its application in foundries is highly restricted. In fact, the main consumers of this product are stainless steel mills in China, because of their capacity to reduce carbon and other undesired elements [5]. Ferronickel is a ferroalloy containing mainly iron and nickel. It is supplied in the shape of flowable granules with a typical particle size between 2 and 50 mm. Part of the production process is a refining step that reduces the amount of carbon, silicon, manganese, sulfur, and phosphorus to an acceptable level for foundries."
