Abstract: A method of making a bearing composed of a bronze preform having aluminum or aluminum alloy cast thereabout. The method includes the step of placing the bronze preform in a mold so as to be supported at one end thereof. The bronze preform is formed of a bronze having lead with a determining melting point and boiling point. The method also includes the step of providing molten aluminum or aluminum alloy to be fed into the mold after the bronze preform has been placed therein. The molten aluminum or aluminum alloy is at a temperature between the melting point and boiling point of lead in the bronze of the bronze preform. The method further includes the step of feeding the molten aluminum or aluminum alloy into the mold under pressure after the bronze preform has been placed therein. The molten aluminum or aluminum alloy contacts the bronze preform and produces a molten lead during partial erosion of the surface thereof.
