High bronze is the ideal choice of the bearing oil free boundaries. Because it is free cutting and keep good thermal conductivity and lubricity, because it contains lead. The lead content in these alloys is usually between 7% and 30%. These alloys performed well in the work environment more bad of the place, such as foreign bodies exist in the environment, dust and other foreign matter. High lead alloy can protect the shaft wear and tear, because of their good toughness.
