Brass plate is a widely used lead brass with good mechanical properties, good machinability, and can withstand hot and cold pressure processing. sets etc. Tin brass plate has high corrosion resistance, good mechanical properties, good pressure workability in cold and hot states, and can be used for corrosion-resistant parts on ships, parts and conduits in contact with steam, oil and other media.
2.Product Characteristics Of Brass Plate.
Brass is an alloy of copper and zinc. The simplest brass is a copper-zinc binary alloy called simple brass or plain brass. Brass with different mechanical properties can be obtained by changing the zinc content in brass. The higher the zinc content in brass, the higher the strength and the lower the plasticity. The zinc content of brass used in the industry does not exceed 45%. No matter how high the zinc content is, it will cause brittleness and deteriorate the alloy properties. In order to improve certain properties of brass, the brass that adds other alloying elements on the basis of one-dimensional brass is called special brass. Commonly used alloying elements are silicon, aluminum, tin, lead, manganese, iron and nickel. Adding aluminum to brass can improve the yield strength and corrosion resistance of brass, and slightly reduce the plasticity. Brass containing less than 4% aluminum has good comprehensive properties such as processing and casting. Adding 1% tin to brass can significantly improve the resistance of brass to seawater and marine atmospheric corrosion, so it is called "navy brass". Tin also improves the machinability of brass. The main purpose of adding lead to brass is to improve machinability and wear resistance, and lead has little effect on the strength of brass. Manganese brass has good mechanical properties, thermal stability and corrosion resistance; adding aluminum to manganese brass can also improve its performance and obtain castings with a smooth surface. Brass can be divided into two categories: cast and press-worked products.
3.Chemical Composition Of Brass Plate.
It is an alloy composed of copper and zinc. When the zinc content is less than 39%, zinc can dissolve in copper to form single-phase a, called single-phase brass, which has good plasticity and is suitable for hot and cold press processing. When the zinc content is more than 39%, there is a single phase and b solid solution based on copper and zinc, called dual-phase brass, b makes the plasticity small and the tensile strength increases, which is only suitable for hot pressure processing. If you continue to increase zinc If the mass fraction is higher, the tensile strength will decrease, and the no-use value code is represented by "H + number", H represents brass, and the number represents the mass fraction of copper. For example, H68 indicates that the copper content is 68%, and the zinc content is 32%. For the brass, the cast brass has the word "Z" before the code, such as ZH62, such as Zcuzn38, which indicates that the zinc content is 38%, and the balance is copper. Cast brass. H90 and H80 are single-phase, golden yellow, so they are called gold, which are called coatings, decorations, medals, etc. H68 and H59 belong to duplex brass, which are widely used in structural parts of electrical appliances, such as bolts, nuts, washers, springs, etc. In general, single-phase brass for cold deformation processing and dual-phase brass for hot deformation processing.
4.Classification Of Brass Plates.
According to the different types of alloying elements contained in brass, brass is divided into ordinary brass and special brass. Brass for press working is called deformed brass.
(1) Ordinary brass is a copper-zinc binary alloy. Due to its good plasticity, it is suitable for the manufacture of plates, bars, wires, pipes and deep-drawing parts, such as condenser pipes, cooling pipes and mechanical and electrical parts. Brass with an average copper content of 62% and 59% can also be cast and is called cast brass.
(2) Special brass In order to obtain higher strength, corrosion resistance and good casting performance, aluminum, silicon, manganese, lead, tin and other elements are added to copper-zinc alloy to form special brass. Such as lead brass, tin brass, aluminum brass, silicon brass, manganese brass, etc.
(3) The α phase and β phase in special brass are multi-component complex solid solutions, which have a large strengthening effect, while the α and β phases in ordinary brass are simple Cu-Zn solid solutions, and their strengthening effect is low. The data listed in Table 5 can be seen. Although the zinc equivalents are equivalent, the properties of multicomponent solid solutions are different from those of simple binary solid solutions. Therefore, a small amount of multivariate strengthening is a way to improve the properties of the alloy.
5.Uses Of Brass Plates.
It can be used for various deep-drawing and bending parts, such as pins, rivets, washers, nuts, conduits, barometers, screens, radiator parts, etc. It has good mechanical properties, good plasticity in hot state, acceptable plasticity in cold state, good machinability, easy brazing and welding, and corrosion resistance. It is a common brass variety that is widely used.
