Zusammenfassung:The present invention relates to a metal alloy for use at a very high temperature, particularly for use in a method for manufacturing mineral wool by drawing a molten mineral composition, characterized in that said metal alloy contains the following elements, the proportions being given as a percentage by weight of the alloy: Cr 20 to 35 %, Fe 0 to 6 %, W 3 to 8 %, Nb 0.5 to 3 %, Ti 0 to 1%, C 0.4 to 1 %, Co less than 3 %, Si less than 1.5 %, Mn less than 1 %, the remainder consisting of nickel and unavoidable impurities. La presente invención se relaciona con una aleación metálica para uso a muy alta temperatura, en particular la cual puede utilizarse en un proceso para fabricar lana mineral al obtener fibras de una composición mineral fundida, caracterizada porque contiene los siguientes elementos, las proporciones se indican como porcentaje en peso de la aleación: Cr de 20 a 35% Fe de 0 a 6% W de 3 a 8% Nb de 0.5 a 3% Ti de 0 a 1% C de 0.4 a 1% Co menor que 3% Si menor que 1.5% Mn menor que 1% el resto consiste de níquel e impurezas inevitables.
