Supply Shenzhen large diameter corrosion-resistant brass

Brass brass use to do all kinds of deep drawing and bending manufacturing force components, such as pins, rivets, washers, nuts, catheters, pressure gauge, screen, radiator parts. Has good mechanical properties, thermal state plastic, plastic is acceptable under cold, good machinability, easy fiber welding and welding, corrosion resistance, it is widely used an ordinary brass varieties. Brass Introduction Material: H59 brass, H63 brass, H65 brass, H68 brass, H70 brass, H80 brass plate, H85 brass, H90 brass, H96 brass board. Specifications: Diameter: 5-250mm, width: 2000-4000mm. Hardness: O, 1 / 2H, 3 / 4H, H, EH, SH and so on. multiple co Haibo Forum www.51gobxg.com brass yellow brass material classification if it is made of two or more elements consisting bbs.hibet.com Macau www.kkskin.com gold called special brass. The copper alloy of lead, tin, manganese, nickel, iron, silicon composition. Brass has strong wear resistance. Special brass known as special brass, high strength, hardness, resistance to chemical corrosion. There machining mechanical properties are more prominent. The pull from the brass into a seamless copper tube, soft, strong wear resistance. Seamless brass heat exchangers and condensers can be used for low temperature piping, sea transport pipe. Manufacture of sheet, strip, bars, tubing, casting parts. 62% copper 68%, strong plastic, manufacturing pressure equipment. Brass according brass alloy elements contained in different types of brass rods and special brass into ordinary two brass rods. Pressure processing of brass brass called deformation. Brass characteristics brass is an alloy of copper and zinc. The simplest brass rods copper - zinc binary alloy, known as a simple brass or ordinary brass. Changing the amount of zinc in brass brass can be different mechanical properties. Brass zinc content is higher, the intensity is higher, lower plasticity. The brass industry used does not exceed 45%, the high zinc content will be brittle, so that the deterioration of alloys. In order to improve certain properties of the brass, the addition of other alloying elements on the basis of one dollar brass on brass called special brass. Common alloying elements silicon, aluminum, tin, lead, manganese, iron and nickel. Alcan in brass can increase the yield strength and corrosion resistance of brass, slightly lower plasticity. Aluminum containing less than 4% of the brass rod has good processing, casting and other comprehensive performance. Ability brass tube plus 1% tin brass can significantly improve anti-seawater and marine atmospheric corrosion, so called "Navy brass." Tin can improve cutting performance of brass rods. The main purpose of leaded brass to improve machinability and improved abrasion resistance, impact of lead on the strength of brass. Manganese brass rod has good mechanical properties, thermal stability and corrosion resistance; increase in manganese brass aluminum, it is also possible to improve its performance, the smooth surface of the casting. Brass casting and pressure processing can be divided into two types of products. Brass manufacturing principle (1) All the elements are, without exception, lower brass electrical and thermal conductivity, where the elements dissolved in the brass, resulting in brass lattice distortion, the free electrons directional flow generated wave scattering, resistivity increases, whereas no solubility or few elements in solid solution in brass, brass electrical and thermal effects on small, special should be noted that some elements in Brass in solubility as the temperature decreases drastically reduced to elemental metal compound precipitated, both solution and dispersion-strengthened alloy brass, and much lower electrical conductivity, which is the study of high strength and high conductivity alloy It is an important alloying principle, there should be pointed out that an alloy of iron, silicon, wrong, chrome and brass consisting of four elements is extremely important high strength and high conductivity alloys; the influence of alloying elements on the Brass Performance It is additive, which is famous for CoCr -Zr alloy high strength and high conductivity alloys; (2) corrosion resistant alloy of copper-based organization should be single-phase, to avoid electrochemical corrosion caused by the second phase in the alloy. For this reason the addition of alloying elements in brass tube should have a lot of solid solubility, even infinitely miscible element in the single-phase engineering applications brass, bronze tube, white brass has excellent resistance corrosion performance, it is important to heat exchange material. (3) wear-resistant copper-based alloy are present in the soft phase and a hard phase, so you must make sure that when alloying elements added in addition to a solid solution in copper, but also should have a hard phase precipitation, brass alloy Typical hard phases have Ni3Si, FeALSi compounds. In recent years, the development of automobile synchronizer gear alloy phase is a soft phase, negative phase of the hard phase, a phase of not more than 10%. (4) solid-state transformation of polycrystalline brass alloy has damping properties, such as Cu - Mn alloy, an alloy in the solid state thermo-elastic martensitic transformation process has memory properties, such as a Cu - Zn Al, Cu an Al a Mn alloy. (5) brass color can be changed by means of the addition of alloying elements, such as the addition of zinc, aluminum, tin, nickel and other elements, as content changes, the color red also occurred Hitodo change one yellow and one white, reasonably control the content of the materials and get fake imitation gold silver alloy. (6) alloying elements brass and alloy chosen should be common, inexpensive and pollution-free, added a few elements should be in line with the principles of pluralism, alloy materials capable of utilization, the alloy should have excellent process performance, suitable for processing into a variety of finished and semi-finished products.
