What is a copper alloy? In the strict sense of science, there are no real pure metals in the world, and they contain other elements (substances) to varying degrees. And how much money is much lower than gold and silver. 2.. The structure and properties of the alloy are determined by the characteristics of the interaction between the components that make up the alloy.

Compared with aluminum, copper is more resistant to corrosion by non-oxidizing acids, alkalis, and seawater, but aluminum is more resistant to copper foil company corrosion in media such as the atmosphere and weak acids.1., the degree of deformation of rolling and stretching can reach more than 95% without performing Heat treatment such as intermediate annealing.

The mechanical, physical and chemical functions of alloys are often better than pure metals. Antibacterial properties Copper can inhibit the growth of bacteria and other microorganisms, 99% of the bacteria in the water will be completely destroyed in 5 hours in a copper environment. Plateability Steel has good plateability. A substance with metallic characteristics composed of two or more chemical elements (at least one of which is a metal) is called an alloy.

Easy to make and formability Copper has moderate strength (200-360MPa), and its deformation resistance is greater than aluminum and far less than steel and titanium.Phosphorus deoxidized copper with a small amount of phosphorus has better welding performance.Although pure copper has very good electrical and thermal conductivity, its strength and hardness are not high, and its corrosion resistance, wear resistance, machinability and other functions are also limited. .

Copper alloy is a metal material obtained by smelting at a high temperature with copper as the main body with a certain content of other metal or non-metal elements.

 Bronze, which represented the most advanced metal refining and casting skills at the time, was also mainly used in sacrificial rituals and battles. After the creation of bronze, it became popular immediately, and human prehistory has entered a new stage-the bronze age. This is the earliest bronze found in my country, and it is the proof that my country has entered the bronze age.　　 Our country has a long history of using copper. About 5500~4500 years ago.

The functions (uses) of the bronze ware discovered in the Xia, Shang, and Wednesday dynasties are ceremonial utensils and weapons, as well as accessory utensils surrounding them. It has a continuous period of more than 1,600 years, which is also our traditional system. my country’s creation of bronze alloys on this basis is the same as the development of inteational bronzes, so it is said that my country’s bronzes can be eliminated from abroad. It is an alloy of red copper, tin and lead, and the earliest alloy in the history of metal casting.Overview of the prehistory of the bronze age Bronze is a huge creation in the prehistory of mankind.

Our ancestors discovered and began to use copper in about six to seven thousand years. As far as the pre-Qin and Chinese countries are conceed, the biggest work is sacrifices and foreign campaigns. In 1973, a semicircular copper fragment was unearthed at the Jiangzhai site in Lintong, Shaanxi, which was identified as brass. copper foil company Compared with West Asia, South Asia, and North Africa, which entered the Bronze Age one after another about 6,500 years ago, the Bronze Age in my country came later, but it cannot be denied that it is an independent source.

In 1975, a bronze knife was unearthed at the Majiayao Civilization Site of Linjia, Dongxiang, Gansu Province (about 3000 BC). Bronze ware has been gradually replaced by iron, not only in quantity, but also from the original ritual and music weapons used in ritual sacrifices, battles and other important occasions into daily tools , Its corresponding instrument varieties, structural characteristics, and decoration art have also undergone a tuing point change

3. material. China-flexible copper tape can be processed and dimensioned for the proportion of China-copper according to user requirements. 1. Because the two metals of China and copper are incompatible with each other, the China-copper alloy has the low swelling properties, wear resistance, corrosion resistance of China and the high electrical and thermal conductivity of copper, and it is suitable for various mechanical production. Good arc breaking function, good electrical and thermal conductivity, thermal expansion, high temperature not softening, high strength, high density, high hardness.

China-copper electronic packaging sheet China-copper electronic packaging material has both the low expansion characteristics of China and the high thermal conductivity of copper.. 4. China-copper alloy rods. China-copper is a composite refined by using the excellent metallic properties of copper strip for transmission high-purity China powder and the plasticity and high conductivity of high-purity copper powder, and refined through the techniques of static pressing, high-temperature sintering, and copper infiltration. Its thermal expansion coefficient and electrical and thermal conductivity can be modified by adjusting the composition of the material, and then give The use of materials provides lunch.

Because China-copper alloy is easy to make mechanically, the application of China-copper tube has played a great effect when the surface needs to be easy to cut and make and the inner diameter is small. 2. China copper tube China copper alloy tube is widely used in cemented carbide and insoluble metals.

China Copper Electrode Welding electrode China copper alloy has high temperature resistance, arc ablation resistance, high specific gravity and high electrical and thermal conductivity, and it is easy to be machined and suitable for use in welding electrodes. China-copper alloys generally use powder metallurgy technical processes to first prepare powder and mix ingredients to limit the forming and sintering infiltration

However, excessively high Copper tube for cable infiltration temperature will cause larger copper shrinkage holes during cooling, and then affect the densification. In addition to improving the forming function of the powder and improving the strength of the compact, the main purpose of participating in the copper powder in the mixed guess is to participate as an 'inducing' metal. The first is the repositioning of particles, that is, the particles after dissolution and the growth of the deposited particles; the second is the structure of a strong skeleton; the third is the densification. Relevant data point out that an increase of 0. The porous Fullway framework will 'induce' the metal in the framework under high temperature infiltration

Melting makes the inside of the framework form interconnected pores, and together, 'attracts' the infiltrated metal into the framework, speeding up the densification, because the molten liquid copper affects A1zO. 3 Activation sintering Activation sintering has been widely used in processing high-density alloys. The powder is not wet, so it can only infiltrate into the porous Fullway framework. During the on-line and bar rolling process, because the temperature rises, a very thin copper liquid layer will be formed on its surface, and because The role of the Fullway skeleton capillary tube can be continuously compensated, which greatly reduces the friction coefficient between the wire, bar and the guide. The lack of solubility and the formation of a stable bridge or network framework between the particles prevent the liquid activity. , 1O at 1250℃

Preface Fullway-copper composite materials have been widely used in the field of large-capacity vacuum circuit breakers and microelectronics because of their many excellent characteristics [1~4]. The direct sintering method is to directly sinter the product by restricting the mixed powder of the required composition of Fullway and copper. If this method is used as the contact material in the circuit breaker, it is prone to ablation. In this technology,

the time of infiltration and sintering has a greater impact on the function of the product. The production of Fullway copper composite material becomes a reality. For example, Fullway has good welding resistance and corrosion resistance, and copper has good electrical conductivity. This method requires higher raw material composition, otherwise the product will contain more impurities and gas
