CuZn25Al5Mn4Fe3 Graphite Plugged Bronze Bushings are specifically designed for mine exploiting equipments, where durability and reliability are paramount. These bushings are made from a unique alloy composition of copper, zinc, aluminum, manganese, and iron, which offers exceptional strength and wear resistance. The addition of graphite further enhances their durability, making them suitable for use in the harshest mining environments.

The graphite plugged design of these bushings provides excellent lubrication and reduces friction, ensuring smooth operation even under high loads and speeds. This feature also helps to extend the bushings' lifespan, reducing the need for frequent replacements.

CuZn25Al5Mn4Fe3 Graphite Plugged Bronze Bushings are an ideal choice for mine exploiting equipments due to their superior performance and durability. Wh used in drilling machines, excavators, or other mining equipment, these bushings will ensure efficient and reliable operation, maximizing productivity and minimizing downtime.

Material:CuZn25AI5Mn4Fe3

High strength brass, chemical formula is ZCuZn25Al6Fe3Mn3, mechanical properties are zinc content is different, mechanical properties are not the same, pressure processing properties have good plasticity, can withstand cold and hot processing.
Alloys consisting of more than two elements are called special brass.Such as aluminum, lead, tin, manganese, nickel, iron, silicon composed of copper alloy, high strength brass is one of them.High strength brass has strong wear resistance, high strength brass high strength, hardness, strong resistance to chemical corrosion.Also cutting mechanical properties are very superior.High - strength brass is often made into manufacturing plate, strip, bar, pipe, casting parts and so on.

Chemical composition

The chemical formula of high strength brass is ZCuZn25Al6Fe3Mn3, containing about 65% copper and 24% zinc.Aluminum improves the strength, hardness and corrosion resistance of brass.There are three kinds of microstructure of brass at room temperature: brass containing less than 35% zinc.
Pressure working property
High strength brass has good plasticity, can withstand cold and hot processing, but in forging and other hot processing easy to appear medium temperature brittleness, the specific temperature range varies with the content of Zn, generally between 200 ~ 700℃.Therefore, the thermal processing temperature should be higher than 700℃.

Mechanical properties of

The mechanical properties of high strength brass vary with their zinc content. For solid brass, b and increase with the increase of zinc content.Therefore, the copper zinc alloy containing more than 45% zinc has no practical value.Standard high strength brass brinell HB > 200, compressive strength > 600MPa, elongation > 10%.

Application field

Colliers 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 matrix, and embedded radial arranged orderly cylindrical polymer filler for friction materials (general graphite, molybdenum disulfide, , such as oil lubricant), its superiority lies in its made of copper alloy and non-metallic antifriction material has the respective complementary advantages, not only has high bearing capacity, and break through the boundaries of generally depends on the oil film bearing grease lubrication, achieve no oil lubrication,The embedded solid lubrication is easy to form the lubrication film, which greatly improves the friction and wear performance, and is stable, reliable and cost-effective.Compared with compound 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, tire vulcanizer, trailer balance beam, vacuum switch, etc.

Structure Characteristics and Applications

VSB-50 Solid Lubricating Bearing is produced by strengthening brass that has good physical performance and good capability for casting. What's more, the brass material has pretty good anti-erosion abitity in air, fresh water and sea water. The surface is regularly and finely machined with sockets in which particular solid lubricant is filled. The product is widely used on consecutive casting and rolling machines, mine-exploiting equipments, ships, steam engine, etc.

Solid Lubricant Casting Aluminum Bronze Bearings Bushings

SOLID LUBRICANT SLIDING BEARINGS material is made of strong cast bronze based metal with special solid lubricants embedded. The base metal withstands high load and the solid lubricants provide self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high/low temperature with low speed. This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion.
