Изобретение относитс  к области изыскани  антифрикционных сплавов на основе меди. Известен сплав на основе меди, содержащий , %:This invention relates to the field of copper based anti-friction alloys. Known alloy based on copper, containing,%:

Олово4,0-10,0Tin4.0-10.0

Свинец5,0-25,0Lead5.0-25.0

Фосфор0,5- 2,5Phosphorus 0.5-2.5

Предложенный сплав отличаетс  от известного более низким содержанием олова, что улучшает эксплуатационные свойства сплава. Предложенный сплав имеет следующий химический состав, %:The proposed alloy differs from the known lower tin content, which improves the performance properties of the alloy. The proposed alloy has the following chemical composition,%:

Олово0,9- 1,5Tin0.9-1.5

Свинец7 -10Lead7 -10

Фосфор1,5- 2,5Phosphorus1.5-2.5

Эксплуатационные качества золотниковой пары оцениваютс  по герметичности при рабочих давлени х и усили м открывани  крана. При давлени х воздуха в кране 150- 250 кг/см и неоднократном переключении его (8-10 раз) «Травлени  воздуха не наблюдаетс . При опрессовке крана водой под давлением 450 кг/см разрушени  деталей не наблюдаетс .The performance of a spool pair is judged by the tightness at operating pressures and valve opening forces. When the air pressure in the faucet is 150-250 kg / cm and repeatedly switching it (8-10 times), no air etching is observed. When crimping a crane with water under a pressure of 450 kg / cm, there is no destruction of parts.

В результате улучшенных экснлуатационных и антифрикционных свойств золотников из предложенного сплава ресурс издели  увеличен вдвое.As a result of improved operational and antifriction properties of the spools of the proposed alloy, the life of the product has been doubled.

Механические свойства сплава следующие: Твердость по Бринеллю, кг/мм 60-80 Предел прочности, кг/мм 18-28The mechanical properties of the alloy are the following: Brinell hardness, kg / mm 60-80 Strength, kg / mm 18-28

Предмет изобретени Subject invention

Сплав на основе меди, содержащий олово, свинец, фосфор, отличающийс  тем, что, с целью улучшени  эксплуатационных свойств, его компоненты вз ты в следующем соотношении , %:Copper-based alloy containing tin, lead, phosphorus, characterized in that, in order to improve the performance properties, its components are taken in the following ratio,%:
