The research results of hardness and abrasion resistance of two commercial nickel-based alloys — Ceranium CN and Magnum AN designed for microcasting applied on dental-prosthetics are presented. Cast samples were made in prosthetic laboratory conditions of Roko production line. Moulds were produced by the lost wax method and poured by use of centrifugal casting method. Hardness tests were conducted by means of Vickers method. The abrasion resistance was evaluated on a tribological tester working in a pin–on–disc system, making measurements of temporary weight losses of samples. On the basis of executed measurement, it was found that Magnum AN alloy possesses better tribological properties than Ceranium CN alloy. Using percentage comparison criteria, it was agreed that Magnum alloy cast in relation to Ceranium alloy cast indicate about 25% higher abrasion resistance and nearly 10% higher hardness. Tribological research also showed that abrasion kinetics of both alloys is linear.
