The plain bearing alloy which consists of the tin basic white metal

摘要

Being the plain bearing alloy which consists of the tin basic white metal, antimony and 1 - 10 as a main alloy element weight % those which include the copper are stated. In order to obtain satisfactory strength quality with high environmental cooperativeness without making worn quality dangerous, in regard to the element to which this group is used the element of 1 types, at least from the element group where the white metal which does not have cadmium, the lead, arsenic or the chrome excluding the inevitable impurity, as a main alloy element 4 - 30 weight % includes antimony, 0.2 - 2.6 weight % includes at all density in regard to the element to which this group is used the element of 1 types, at least from the element group which includes the cobalt, manganese, scandium and germanium, at the same time includes magnesium, the nickel, zirconium and titanium 0.05 -1.7 weight % it includes at all density, total ratio of antimony and the copper, is highest in the antimony content which at least is suitable to 3 times that of copper content and 35 weight % it is proposed that is.
