We produce nickel matte at the Boliden Harjavalta smelter in Finland from nickel concentrate from our own Kevitsa mine in northern Finland and external mines. Harjavalta is also the only large-scale nickel smelter in Europe. Our nickel matte is further sold to refineries globally to be used in a variety of special applications such as high-nickel alloys for the aerospace industry. Superalloys have found extensive use in many high-temperature applications, such as automotive exhaust valves, furnace structural parts, heat treatment equipment, rocket engines, and, most significantly, in the hot zones of gas and jet turbines for electricity generation or to power aircraft. And in the chemical processing sector, they are valued for their corrosion resistance.
