High tensile brass alloy solid lubricant embedded

High strength brass brass

Basic Information

Please check the type/dimensions/specifications of the part MPBZ10-12 in the Oil Free Bushing - Brass Alloy, Straight, I.D. F7 (China oilless bushing) series.

A variety of alloys consisting of more than two elements are called special brasses. Such as aluminum, lead, tin, manganese, nickel, iron, silicon composition of copper alloy, high force brass is one of them. High strength brass has strong wear resistance, high strength brass, hardness, strong chemical corrosion resistance. There are also machining mechanical properties that are very superior. High strength brass is often used to manufacture sheet, bar, bar, pipe, casting parts, etc. Chemical composition

The chemical formula of high strength brass is ZCuZn25Ai6Fe3Mn3, which contains about 65% copper and 25% zinc. Aluminum improves the strength, hardness, and corrosion resistance of brass. There are three kinds of brass at room temperature: brass with zinc content below 35%, and the microstructure at room temperature is composed of single-phase A solid solution, known as A brass.

■ Application field

brass application is very extensive, the casting made of bearing and bushing, domestic now mainly made of high strength brass for matrix solid lubrication oil-free bearings (hereinafter referred to as solid embellish bearing), is to use brass Gao Ligao strength as a matrix, and embedded radial arranged orderly cylindrical polymer filler for friction materials (as for graphite, 2 - molybdenum, ethylene, oil, and other lubricants), its superiority lies in its made of copper alloy and non-metallic antifriction material has the respective complementary advantages, not only has the high bearing capacity, and breakthrough - the line on the oil film bearing grease lubrication, achieve no oil lubrication, The embedded solid lubrication is easy to form lubrication film, which plays a great role in improving the friction and wear performance, and is stable, reliable and cost-effective. Compared with the composite oil-free bearing, it has the advantages of good machinability, high precision, strong bearing capacity, and good wear resistance. The self-lubricating guide bush guide can be used in many fields such as engineering machinery joints, such as excavator, mining scraper, the rotating drill, concrete pump truck, rock drill machine, hoist, port cranes, etc., and metallurgical machinery casting machinery, water conservancy machinery, transportation machinery, rolling mill, bottle blowing machine blown film machine, injection molding machine cross-clamping differential, tires mechanism, trailer balance beam, vacuum switch, etc.
