    • A cast-iron product has a composition of 4.3-4.9 wt. % Carbon Equivalent (CE), 0.25-0.5 wt. % Chromium (Cr), 0.05-0.12 wt. % Tin (Sn), 0.4-1.2 wt. % Manganese (Mn), 0-0.1 wt. % Phosphorus (P), and 0-0.15 wt. % Sulfur (S), with the balance being Iron (Fe). A brake assembly comprises a sliding element made of such a cast iron, and the sliding element is adapted to slideably contact with a friction element or elements made of non-asbestos material and constitute the assembly. Further, a method of producing a cast iron product comprises the steps of casting a cast iron having a composition of 4.3-4.9 wt. % Carbon Equivalent (CE), 0.25-0.5 wt. % Chromium (Cr), 0.05-0.12 wt. % Tin (Sn), 0.4-1.2 wt. % Manganese (Mn), 0-0.1 wt. % Phosphorus (P), and 0-0.15 wt. % Sulfur (S), with the balance being Iron (Fe), releasing a mold at a temperature not less than A.sub.1 allotropic transformation temperature, and cooling the cast iron at a relatively high cooling rate.
