A spheriodal cast alloy for producing cast iron products with great mechanical strength, high-wear resistance and a high degree of ductility. The alloy comprises the following as non-iron components: between 2.5 and 2.8 wt. % C, between 2.4 and 3.4 wt. % Si, between 0.02 and 0.08 wt. % P, between 0.02 and 0.06 wt. % Mg, between 0.01 and 0.05 wt. % Cr, between 0.002 and 0.02 wt. % Al, between 0.0005 and 0.015 wt. % S, between 0.0002 and 0.002 wt. % B and conventional impurities. The alloy contains between 3.0 and 3.7 wt. % C, between 2.6 and 3.4 wt. % Si, between 0.02 and 0.05 wt. % P, between 0.025 and 0.045 wt. % Mg, between 0.01 and 0.03 wt. % Cr, between 0.003 and 0.017 wt. % Al, between 0.0005 and 0.012 wt. % S and between 0.0004 and 0.002 wt. % B. The alloy is used for example to produce chassis parts or brake discs in the automobile industry.
