FIELD: stomatological materials.
SUBSTANCE: invention relates to stomatology-destination gold-based cast alloys, which are used for manufacturing stomatological structures such as removable clasp dental prostheses. Alloy is composed of, wt %: silver 10-12, platinum 4-5, copper 10-12, zinc 0.6-1.0, iridium 0.05-0.15, and gold in balancing proportion, provided that (Au+Pt+Ir) =75, Ag.Cu=0.9-1.1, Ag/Pt=2.0-2.4, and (Ag+Pt)/(Cu+Zn)=1.2-1.4. Yellowness index is more than 24.
EFFECT: increased corrosion resistance and imparted mechanical properties ensuring rigidity of stomatological structure.
