A variety of alloys consisting of more than two elements are called
special brasses. Such as aluminum, lead, tin, manganese, nickel,
iron, silicon composed 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
machining mechanical properties are also very superior. High
strength brass is often used to manufacture sheet, bar, bar, pipe,
casting parts, etc.

Application domain editor
Colliers brass application is very extensive, the casting made of
bearing and bushing, domestic 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 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, tire vulcanizer, trailer balance beam, vacuum switch,
etc.
