Tin bronze is a non-ferrous metal alloy with the smallest casting shrinkage rate, used to produce castings with complex shapes, clear contours, and low air tightness requirements. Tin bronze is highly corrosion-resistant in the atmosphere, seawater, freshwater, and steam, and is widely used in steam boilers and ship parts. Phosphorus containing tin bronze has good mechanical properties and can be used as wear-resistant and elastic parts for high-precision working machines. Lead tin bronze is commonly used as wear-resistant parts and sliding bearings. Zinc tin bronze can be used as a highly airtight casting.

Aluminum bronze series products have high strength, good wear resistance, corrosion resistance, good processing performance, as well as excellent thermal conductivity and stable mechanical properties. They are mainly used in the processing and manufacturing of various components that require high-strength mechanical properties. They are widely used in industries such as shipbuilding, aerospace, machinery manufacturing, military equipment, etc., such as transmission shafts, bearings, gear turbines, flanges, valve components, bolts and nuts, non sparking tools, molds, etc.

Lead bronze is a basic alloy composed of Pb, Zn, and Sn, with a lead content generally above 8%. The composition of Pb in bronze can enhance the anti fatigue strength, thermal conductivity, and wear resistance of the body, as well as the excellent quality of not cracking under working conditions with impact loads. Lead bronze has lower load-bearing performance than aluminum bronze, but its wear reduction and fatigue resistance are much higher, and it is generally used in high-speed operating parts. Such as bimetallic bearings, wear-resistant parts, and bearings.

High strength brass graphite self-lubricating is a solid lubricating material made of high-strength brass as the substrate, with ordered and appropriately sized holes drilled on the substrate, and then embedded with oil containing graphite, molybdenum sulfide, or polytetrafluoroethylene+graphite+paraffin particles. It breaks through the boundary of general bearings relying on oil film lubrication. When the bearing works under oil-free lubrication conditions, due to the operation of frictional heat, the solid lubricating material will gradually transfer to the working surface of the friction pair, thereby reducing the friction coefficient. Its material has more than twice the hardness of ordinary copper sleeves, and its wear resistance is also twice as high in low-speed and heavy-duty environments. At present, it is widely used in low-speed and heavy-duty environments such as metallurgical continuous casting machines, steel rolling equipment, mining equipment, ships, steam turbines, injection molding machines, woodworking rotary cutting machines, and equipment production lines.

Zinc based wear-resistant alloys have good mechanical properties, hardness, and wet wear resistance, and are suitable for gravity casting, casting bearings, worm gears, nuts, and other products for various lifting equipment, machine tools, and water pumps; However, the elongation, impact toughness, and heat resistance are still poor. Zinc has strong chemical activity and poor corrosion resistance, making it unsuitable for working under conditions such as acid, alkali, and seawater; When the lubrication conditions are good, it can replace tin bronze and Babbitt alloy in general mechanical equipment bearings, shaft sleeves, pressure plates, etc. Its linear expansion coefficient is relatively large, and the clearance between it and the shaft should be slightly increased.
