Copper tape for transformer installation

Tin-free bronze is also called Wuxi bronze, which generally has high corrosion resistance, outstanding lubricity, high electrical conductivity, and also has outstanding mechanical properties. These alloys are also called special bronzes. Special bronze can be used to manufacture mechanical parts and so on. Tin bronze (tin phosphor bronze) is an alloy Copper tape for transformer installation that has been used in my country for a long time..

Bronze is an alloy of copper and tin, and the tin content is about 5% to 10%. Used to cast bearings, pump housings, valves, gears. Sometimes it also refers to a binary or multiple alloy composed of copper and aluminum, silicon, beryllium, and manganese. This alloy has good castability and high corrosion resistance.Free-cutting phosphor bronze is Bronze is a large variety, including phosphor bronze and phosphor bronze. It has strong chemical stability in sea water, dilute sulfuric acid, solution, and very dilute sodium carbonate solution

It is suitable for alloys that have a quenching effect after heat production and cooling, such as 6063. T5: After hot production, it is quenched and then artificially aged. Products made without a specific chain degree, such as kneaded, hot-rolled, and cast products. This quenching and tempering is suitable for alloys that have a quenching effect after cooling after hot production, such as 6063. T4: Natural aging treatment after solution treatment.

The process of these treatments is called conditioning, and the result of conditioning is the degree of chain.Heat treatment of aluminum alloy 1. Its intention is to improve the resistance to hard corrosion cracking and avoid deformation during quenching. H112 does not deliberately manipulate the production of hardened products, but the mechanical properties must be ensured. If higher strength is not ensured, it can also be regarded as T6 chain degree.

Therefore, it is necessary to carry out a variety of special cutting depth production for metal composite bearing materials according to different bearing products to complete the whole process of production of products such as bearing bushes, bushings, thrust bearing rings, and thrust bushings

The nano-structured Fullway-copper composite material not only arranges uniform structure, high fine density and easy to obtain high-precision, net-shaped messy products.95% and total impurities less than 100mg/kg. Therefore, it is necessary for the research and development of shock-resistant Fullway wire to optimize the system around the subject of doping, complete the goal of simultaneously enhancing the high-temperature strength, creep resistance, and room temperature strength of the Fullway wire after high-temperature recrystallization, and then achieve better results.

In terms of refinement research, the most researched is nano-Fullway powder and nanocrystalline Fullway-based alloy composite powder. Its primary uses include (1) carbides used for cutting, welding and spraying, such as Fullway carbide.5MPa·M1/2 and 843MPa, 10. 2. Now, the international research on refractory materials has evolved from the traditional 'high purity, ultra-fine, uniform' to 'nano, composite planning and integrated production.

China copper tubes company

After being hardened, its tensile strength and hardness increase, while plasticity decreases. The first is to improve the tensile strength and improve the technical code for 'H + the symbol of the main element (except zinc) + the mass fraction of copper + the mass fraction of the main element + the mass fraction of other elements'. Nickel content is generally 10%, 15%, 20%, the higher the content, the whiter the color. commonly used are Qsn43 Qsn6. A.is an alloy of copper and nickel. Cast brass. 2) Special bronzes join other elements to replace tin, or Wuxi bronzes.

The casting shape is messy. For example, Qal7 indicates that the aluminum content is 5%, and the other aluminum bronze ZQsn101 that is copper indicates that the tin content is 10%. It is suitable for castings with messy shapes but low density requirements, such as sliding bearings, gears, etc.

They are satisfied with various corrosion resistance and special electrical and thermal functions. Industrial copper-nickel alloys can be divided into structural copper-nickel alloys and electrical copper-nickel alloys according to their functional characteristics and application ranges. Most special bronzes have higher mechanical properties, wear resistance and corrosion resistance than tin bronzes. H68 and H59 belong to dual-phase brass, which are widely used in structural parts of electrical appliances, such as bolts, nuts, washers, tension springs, etc. For cast products, add the word 'Z' before the code. When the tin content is greater than 10%, it is suitable for casting.

Red copper is China copper tubes company with a high copper content, and the total content of other impurities is below 1%. In addition to brass and white copper, other copper alloys are collectively called bronze. Casting tin bronze is directly sold as ingots, and cast into castings by the foundry. Since a and are near the electrode potential, and the tin in the composition produces a fine tin dioxide film after nitriding, the corrosion resistance of the atmosphere and seawater is increased, but the acid resistance is only poor. Pure copper and nickel can significantly improve strength, corrosion resistance, electrical resistance and thermoelectricity
