Jackie
Classification habits of copper and copper alloy in my country are classified according to color, generally divided into copper: refers to pure copper; brass: refers to alloy based on copper and zinc; bronze: refers to copper -based alloy except copper nickel, copper -zinc alloy other than copper, copper -zinc alloys other than copper, copper -zinc alloy, Bronze: Copper nickel alloys. Here are the differences and classifications of pure copper and brass that I have compiled for everyone. I hope you like it.
The difference between pure copper and brass 1. Copper
red copper is pure copper, also known as copper, pure copper density is 8.96, melting point is 1083 ℃ Essence It has good conductivity and thermal conductivity, excellent plasticity, easy to heat up and cold pressure processing. It is used in large quantities to manufacture good conductivity products such as electric wires, cables, brushes, and electro -sparks.
is named after purple -red. It is not necessarily pure copper. Sometimes it also adds a small amount of deoxysentery or other elements to improve the material and performance, so it is also attributed to copper alloy. Chinese copper processing materials can be divided into: ordinary copper (T1, T2, T3, T4), anaerobic copper (TU1, TU2, and high -purple, vacuum oxygen copper), TuP, TUMN), add a small amount of alloy, add a small amount Special copper (arsenic, copper, silver copper) of elements.
The conductivity and thermal conductivity of copper are second only to silver, and are widely used to make conductive and thermal equipment. Copper has good corrosion resistance in the atmospheric, seawater and certain non -oxidized acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and various organic acids (acetic acid, citric acid) for chemical industry. In addition, the copper has good welding properties, which can be made into various semi -finished products and finished products through cold and thermoplastic processing. In the 1970s, the output of copper than other types of copper alloy was exceeded.
The trace impurities in copper have a serious impact on the conductivity and thermal conductivity of copper. Among them, titanium, phosphorus, iron, silicon, etc. significantly reduce the conductivity, while cadmium, zinc, etc. have a small impact. The solid solution of oxygen, sulfur, selenium, and cymbal in copper is very small. It can be brown into crispy compounds with copper, which has little effect on conductive, but can reduce processing plasticity. When ordinary copper is heated in a restored atmosphere of hydrogen or carbon dioxide, hydrogen or carbon monoxide is easy to act with the oxide of the Copper (CU2O) in the crystal world, producing high -pressure water vapor or carbon dioxide gas, which can break the copper. This phenomenon is often called "hydrogen disease" of copper. Oxygen is harmful to the welding of copper. The 生 or lead and the copper formation of a low melting point crystal make the copper produce hot and brittle; and the crispy 铋 is distributed in the crystal world, and the copper produces cold crispy. Phosphorus can significantly reduce the conductivity of copper, but it can improve the liquidity of copper liquid and improve welding. A moderate amount of lead, sulfur, sulfur, etc. can improve cutability.
2. BOC
The copper alloy with zinc as the main addition of elements, which has a beautiful yellow, collectively referred to as brass. Copper zinc dual alloy is called ordinary brass or simple brass. Snakes above three yuan are called special brass or complex brass. The brass alloy with a zinc containing less than 36%is composed of a solid -soluble and has good cold processing performance. For example, 30%of brass containing zinc is often used to make shells, commonly known as bullet shell brass or seven -three bronze. The brass alloy with zinc -containing 36-42%consists of a solid solution, the most commonly used is 40%of the six four bronze containing zinc. In order to improve the performance of ordinary brass, other elements are often added, such as aluminum, nickel, manganese, tin, silicon, lead, etc. Aluminum can improve the intensity, hardness and corrosion resistance of brass, but reduce the plasticity, suitable for sea wheel condensate tube and other corrosion parts. Tin can increase the intensity of brass and corrosion resistance to seawater. Lead can improve the cutting performance of brass; this is often used as clock parts. Bronze castings are often used to make valve and pipeline accessories.
The simplest brass is copper-zinc binary alloy, called simple brass or ordinary brass. Changing the zinc content in brass can obtain brass with different mechanical properties. The higher the zinc content in brass, the higher the strength, and the lower plasticity. The amount of brass adopted in the industry does not exceed 45%, and the high amount of zinc will produce brittleness, which will make the alloy performance bad. 1%of the tin can significantly improve the ability of brass to resist sea water and ocean atmospheric corrosion, so it is called "naval brass". Tin can improve the cutting performance of brass. Lead bronze is what we usually call the citrus copper. The main purpose of leading lead is to improve the cutting of cutting and abrasion resistance, and lead has little effect on the intensity of brass. Carving copper is also a type of lead brass. Most brass has good color, processability, ductility, and easy to electroplating or coating.
The brass is divided into:
1) Ordinary brass
The alloy consisting of copper and zinc.
When the amount of zinc containing is less than 39%, zinc can dissolve in copper to form a single phase A, which is called single -phase brass. When the amount of zinc contains is greater than 39%, there are A single phase, and there are B -solid solids based on copper -zinc. It is called double -phase brass. B plasticity is small and the tensile strength increases, which is only suitable for thermal pressure processing.
is represented by "h numbers". H indicates brass, and numbers indicate the mass score of copper. For example, H68 indicates that the copper content is 68%and the zinc content is 32%. The brass, which is cast by the word "Z" in front of the code, such as ZH62.
H90, h80 single phases, golden yellow, so it is called golden color, called plating, decoration, medals, etc.
H68 and H59 are double -phase brass, which are widely used for structural parts on electrical appliances, such as bolts, nuts, pads, springs, etc.
In general, cold deformation processing is used for double -phase brass with single -phase brass heat deformation processing.
2) Special brass
The diverse alloy composed of other alloy elements to ordinary brass is called brass. The often added elements include lead, tin, aluminum, etc., which can be called lead brass, tin brass, aluminum brass. The purpose of the alloy element. It is mainly to improve the intensity of tensile resistance and improve process.
Code: It is represented by the quality score of "H main element symbol (except zinc) copper's mass score main addition element quality score other element quality scores."
For example: HPB59-1 indicates that the mass score of copper is 59%, the mass score of the main addition of elemental lead is 1%, and the remaining amount of lead brass is zinc.
3. Copper
The copper alloy with nickel as the main adding element. Copper nickel dual alloys are called ordinary white copper; white copper alloys with manganese, iron, zinc, aluminum and other elements are called complex white copper. Industrial white copper is divided into two categories: structural white copper and electrician white copper. The characteristics of white copper are characterized by good mechanical properties and corrosion resistance and beautiful color. This white copper is widely used in manufacturing precision machinery, chemical machinery and ship components. Electric white copper generally has good thermoelectric performance. Manganese copper, Kang copper, and copper testing are manganese white copper with different manganese content. It is a material for making precision electrical equipment, barrier, precision resistance, shoulder -to -tables, and thermocouple.
4. Bronze
The original refers to copper tin alloys. After the bronze alloys except brass and white copper are called bronze, and often the first main name in front of the bronze name is the first main main main main Add the name of the element. Tin bronze has good casting performance, good reduction performance, and good mechanical performance, suitable for manufacturing bearing, worm wheels, gears, etc. Lead bronze is a bearing material widely used in modern engines and mills. Aluminum and bronze are high in strength, good abrasion resistance and corrosion resistance, and are used to cast high load gears, shaft sleeves, ship propellers, etc. The elasticity of bronze and phosphorus bronze is high, good conductivity, and is suitable for making precision spring and electrical contact elements. The bronze is also used to make no sparkless tools used in coal mines and oil depots.
Code: The method is composed of "Q Main Elemental Symbols and Quality Scores the Quality Score of Other Elements". The casting product is added in front of the code,
is: QAL7 means 5%aluminum-containing, the remaining aluminum bronze ZQSN10-1 indicates that the tin content is 10%, and other alloy elements The content is 1%, and the remaining tin tin bronze with a copper.
Bronze can be divided into two categories: tin bronze and special bronze (that is, Wuxi bronze).
(1) is a copper tin alloy with tin as the main element. In the formation of A solid solution, the plasticity increases. When the tin content is greater than 5-6%, the solid solution based on the CU31SB8 appears, and the tensile strength decreases. When the tin content is less than 5%, it is suitable for cold deformation processing. When the tin content is 5-7%, it is suitable for thermal deformation processing. When the tin content is greater than 10%, it is suitable for casting.
Classification habits of copper and copper alloy in my country are classified according to color, generally divided into copper: refers to pure copper; brass: refers to alloy based on copper and zinc; bronze: refers to copper -based alloy except copper nickel, copper -zinc alloy other than copper, copper -zinc alloys other than copper, copper -zinc alloy, Bronze: Copper nickel alloys.
