An overview of the editor
Any alloy consisting of more than two elements is 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 hardness, strong chemical corrosion resistance. And machining mechanical properties are also very superior. High-strength brass is often made to manufacture sheet, bar, bar, pipe, casting parts and so on.
Chemical composition editing
The chemical formula of high-strength brass is ZCuZn25Al6Fe3Mn3, containing about 65% copper and about 24% zinc. Aluminum improves the strength, hardness and corrosion resistance of brass. There are three types of brasses at room temperature: brasses containing less than 35% zinc. The microstructure of brasses at room temperature consists of a single-phase solid solution, called brass.
Pressure machining performance editing
High force brass has good plasticity and can withstand cold and hot machining, but it is easy to appear medium temperature brittleness in forging and other hot machining. The specific temperature range varies with the different content of Zn, generally between 200 ~ 700℃. Therefore, the temperature during thermal processing should be higher than 700℃.
Mechanical properties editing
The mechanical properties of high-strength brass vary with zinc content. For brass, B and increase with the increase of zinc content. Therefore, the copper - zinc alloy containing more than 45% zinc has no practical value. HB > 200, compressive strength > 600MPa, elongation > 10%.
Development history editor
The term "brass" was first used in the Classic of Ancient Chinese Buddhism by Dongfangshuo in the Western Han Dynasty: "There is a palace in the northwest, with brass as the wall, and the palace of the Emperor." What kind of copper alloy this "brass" refers to remains to be seen. The book also has the titles of "bronze" and "brass", which refer to the color of ore and smelting products respectively, rather than copper-tin alloy and copper-zinc alloy. Kui of the Song Dynasty wrote "Da Ye Fu", and "it is brass, pit has various names, mountains are many simple", referring to pure copper refined by fire.
The word brass refers to copper and zinc alloy, which was started in the Ming Dynasty, and its record can be seen in the Ming Dynasty Canon: "Jiajing in the example, Tong Bao six million wen, a total of two fire brass 47,272 jin... ." Based on the analysis of the composition of the copper COINS in Ming Dynasty, it is found that the real brass of casting money mentioned in The Ming Dynasty Association Canon appeared much later than other copper alloys, because it is difficult to obtain the metal zinc in brass.
Zinc oxide can be quickly reduced to metallic zinc at 950℃ to 1000℃, while liquid zinc has been boiling at 906℃, so the reduced metallic zinc exists in the form of vapor. When the reaction is reversed on cooling, the vapor zinc is reoxidized from carbon dioxide in the furnace to zinc oxide, so special condensing devices are required to obtain the metal zinc. This is why the use of zinc was much later than that of copper, lead, tin, and iron, and one of the reasons for the late appearance of brass coinage.
However, at the Site of Yangshao culture in Jiangzhai, brass plates and tubes containing more than 20% zinc were unearthed, and two kinds of brass cones were also excavated from the longshan culture in Sanlihe county in Shandong Province. It is obvious that the appearance of these brass objects does not mean that the smelting technology of brass was mastered in prehistoric times, but that people acquired it by accident while using copper-zinc symbionts.
During the Shang and Zhou dynasties, the zinc content of copper ware was very low, generally in the order of 10-z. There were several copper and zinc sweet COINS in the western Han dynasty and Xinmang, among which the content of zinc in some COINS reached 7%, but this does not mean that the copper coin was produced in the Xinmang period of the Western Han Dynasty. Because these alloys are rare, the zinc content is generally much less than the 15 to 40 percent of the actual zinc content of brass. Therefore, we believe that these copper COINS containing zinc were produced during the han Dynasty when the copper and zinc symbionts were used. According to the investigation of the mines concerned, it is found that changwei, Yantai, Linyi and Hubei in Shandong province have copper-zinc co-sources rich in resources, which makes the smelted copper contain a small part of zinc. In tang Dynasty, due to the standardization of casting materials, the content of zinc in the cast COINS was constant.
Brass products remained popular in Europe for about 300 years, starting around 1230 AD, because they were much cheaper than large sculptures. Died in 1231
The statue of Archbishop Welp, in 1864, is the earliest known bronze statue made of brass. The process for casting brass products is as follows: the zinc ore and charcoal are first mixed with the copper block and heated to bind the zinc and copper together. The alloy is then heated to melt, and the copper liquid is then poured into the mold. The earliest Bronzes in England were imported, mainly from Turne. The client may order from Tournay complete gravestones already mounted in beautiful soles or marble pedestals. The way to make a bronze gravestone is to first cast the statue, usually with a silhouette of a canopy around it, then place it on a slab of prefabricated stone and use a knife to carve out human details on the statue. Sometimes alabaster or other inlays were used for the hands and faces. When the statue was safely made, it was fastened to the stone base with a hidden pin in the lead bolt. The statue itself rests on a layer of asphalt. Large bronze statues were cast in sections and then joined together.
Application domain editing
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, ptfe, 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 lubricating film, which plays a great role in improving its friction and wear performance, and is stable and reliable with high cost performance. 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.
