Performance characteristics of high lead bronze

With the development of large-scale machinery and equipment, the requirements for important parts are more stringent. Bearings and bearing bushes, as important wear-resistant parts of large-scale equipment such as metallurgy, electric power, and mining, are subjected to high pressure, impact load and alternating stress during production work, as well as friction, wear, high temperature and various. The corrosive effect of the medium on it. Common tin-based and lead-based babbitt, cast iron-based bearing materials can no longer meet the requirements of use. High lead bronze alloys have excellent dry friction properties, high thermal conductivity, fatigue resistance and anti-seize properties, and are currently widely used.

High lead bronze is a very versatile alloy material. However, due to the great difference in melting point and specific gravity between copper and lead, lead segregation is easy to occur.
High lead bronze has high fatigue strength, thermal conductivity and wear resistance, and will not produce cracks under the working conditions of impact load.
