Lead bronze copper sleeve, material grade C93800, corresponds to domestic grade CuPb15Sn8, C93700, corresponds to domestic grade, ZCuPb10Sn10 (10-10), this material has good sliding and self-lubricating properties in the absence of lubricants and water-based lubricants. Bearings that are easy to cut, have poor casting performance, good corrosion resistance to dilute sulfuric acid, high surface pressure, and side pressure, can be used to make copper cooling pipes for cold rolling mills, parts with an impact load resistance of 50Mpa, and bimetal bearings for internal combustion engines. , mainly used for piston pin sleeves and acid-resistant accessories with a maximum load of 70Mpa.
Tin bronze: A copper-based alloy with tin as the main alloy element is called tin bronze. Tin bronze is widely used in shipbuilding, chemical industry, machinery, instrumentation and other industries. It is mainly used to manufacture wear-resistant parts such as bearings and bushings, and elastic components such as springs. As well as anti-corrosion and anti-magnetic parts, etc., it has high strength, elasticity, wear resistance and anti-magnetic properties. It has good pressure processability in hot and cold states, has high flame resistance against electric sparks, and can be welded and fiber optic. Welding, good processability, the main brands are ZCuSn6Zn6Pb3, ZCuSn10Pb5, ZCuSn5Zn5Pb5, etc.
Lead bronze: A copper-based alloy with lead as the main alloy element is called lead bronze. It has high friction reduction and good machinability. It is easy to weld and braze. It has good corrosion resistance in the atmosphere and fresh water. It only has It can be pressure processed in a cold state. Because lead-containing hot processing can easily cause thermal embrittlement, it is used to make bearings that work under friction. The curling bushing tin bronze is an alloy copper with zinc and lead alloy elements added, and has a high Friction reduction and good machinability, easy to weld and braze, the main brands are Pb15Sn7, Pb20Sn5, Pb10Sn10, etc.
Aluminum bronze: A copper-based alloy with aluminum as the main alloy element is called aluminum bronze. The mechanical properties of aluminum bronze are higher than those of brass and tin bronze. The aluminum content of aluminum bronze in practical applications is between 5% and 12%. Aluminum bronze containing 5% to 7% aluminum has the best plasticity and is suitable for cold working. When the aluminum content is greater than 7% to 8%, the strength increases, but the plasticity decreases sharply, so it is mostly used in the cast state or after hot processing. The wear resistance of aluminum bronze and the corrosion resistance in the atmosphere, seawater, seawater carbonic acid and most organic acids are higher than those of brass and tin bronze. Aluminum bronze can be used to manufacture high-strength anti-wear parts such as gears, bushings, and worm gears. As well as high corrosion resistance elastic components, the main brand is ZCuAl10Fe3.
