Изобретение относится к сплавам благородных металлов на основе палладия, используемых преимущественно в стоматологии в качестве конструкционного материала для зубных протезов, а также в других областях медицины. Технический результат от использования этого изобретения заключается в повышении твердости, предела текучести, улучшении адгеэионных свойств, а также в получении коэффициента термического расширения, позволяющего использовать как импортные, так и отечественные керамические покрытия. Этот результат достигается за счет того, что высокопрочный сплав "Суперпал" на основе палладия с медью 10 - 15 мас. %, золотом и оловом содержит Au 10 - 25 мас. %, Sn 10 - 15 мас. % при соотношении Cu: Sn = 1: 1, кроме того, сплав может дополнительно содержать один или несколько металлов платиновой группы в количестве 0,1 - 5 мас. %.The invention relates to alloys of noble metals based on palladium, used mainly in dentistry as a structural material for dentures, as well as in other fields of medicine. The technical result from the use of this invention is to increase hardness, yield strength, improve adhesion properties, as well as to obtain a coefficient of thermal expansion, allowing the use of both imported and domestic ceramic coatings. This result is achieved due to the fact that the high-strength alloy "Superpal" based on palladium with copper 10 - 15 wt. %, gold and tin contains Au 10 - 25 wt. %, Sn 10 - 15 wt. % with a ratio of Cu: Sn = 1: 1, in addition, the alloy may additionally contain one or more platinum group metals in an amount of 0.1 to 5 wt. %
