COMPOSITION OF NOBLE METAL ALLOY FOR STOMATOLOGICAL PURPOSES

The alloy is used mainly for moulded prosthesis constructions, especially in cases when they are subject to high mechanical-strength loads and strong wear-out. It has a sensibly reduced content of gold and its specific weight is 27% lower, while the solidity and strength is 3.5 to 4.5 times higher t...

Beschreibung
Zusammenfassung:	The alloy is used mainly for moulded prosthesis constructions, especially in cases when they are subject to high mechanical-strength loads and strong wear-out. It has a sensibly reduced content of gold and its specific weight is 27% lower, while the solidity and strength is 3.5 to 4.5 times higher than those of probe 916, with which the use of tooth consturctions, prepared with this alloy is extended over a longer period of time. The alloy contains the following components in %: 53/54 gold; 23/27 silver; 13/16 copper; 3/6 palladium:0.5/1.5 platinum; 1/2 zinc; 0.1/0.6 indium.
