At this moment, the solution turns purple. In printing and dyeing industry, it is used as a mordant and oxygen aid for fine dyeing cloth.Red copper-features high purity, fine arrangement, and extremely low oxygen content.　　 In the high school biological inspection of reducing sugar, copper sulfate is used to make Fehling reagent, and the effect of boiling water bath with reducing sugar to form brick red deposit. copper clad steel strips manufacturer As a bacterial agent in agriculture. Copper-copper sulfate application range 　　 high school chemistry uses anhydrous copper sulfate to check the presence of water vapor. The electroplating industry is used as the main salt and copper ion additive for all-bright acid copper plating.

The coating industry is used as a microbial agent for processing anti-fouling paint on ship [...]

The most outstanding feature is its outstanding wear resistance. , Outstanding wear and corrosion resistance, suitable for making various elastic components.5%, and sometimes an appropriate amount of iron, nickel, manganese and other elements are added to further improve the function., and wear-resistant parts. The English name of phosphor bronze is tinbronze. Corrosion resistance in the atmosphere, fresh water and sea water Very good, machinability is acceptable, welding is not easy to fiber welding, excellent pressure production under hot state.

If it also contains P, it is called phosphor-tin bronze.. Because aluminum bronze containing iron and manganese elements has high strength and wear resistance, it can increase the hardness after quenching and tempering, and has good high temperature corrosion resistance and oxidation resistance. As an elastic alloy, it refers to a copper-tin [...]

814 Electrical conductivity %IACS42 Hardness 185HV Flexural strength Mpa700 Softening temperature ℃900. Concurrently withdraw copper copper, copper scrap, copper wire. Widely used in various industries such as mold making, mechanical equipment, plastics, electronics, hardware products and so on.00 　

Resistance welding electrode, electric spark electrode, high voltage discharge tube electrode, electronic packaging material. It has good arc-breaking performance, good electrical and thermal conductivity, small thermal expansion, no softening at high temperature, high strength, high density and high hardness.00 Copper Cu30.Founded in 2000, Shanghai Metal Materials Co. Tungsten copper is a composite material refined by the technology pure copper strip of static pressure forming,

high temperature sintering, and infiltrating copper, taking advantage of the excellent metal properties of high purity tungsten powder and the plasticity and high conductivity of high purity red [...]

01% is called oxygen-free copper, which is indicated by TU (copper-free), such as TU1, TU2, etc.　　Bronze used to call the alloy of copper and tin bronze, but now it calls copper alloys other than brass bronze. When gas welding, neutral flame or weak carbonized flame is used for copper, and weak oxidation flame is used for brass to avoid zinc transpiration. Tungsten electrode hydrogen arc welding uses direct current direct connection. Bronze is indicated by 'Q,' (green). Commonly used are tin bronze, aluminum bronze and sensitive bronze.　　

Aluminum bronze strengthening treatment methods Aluminum bronze is divided into two categories in a certain sense, one is ordinary aluminum bronze, and the other is special aluminum bronze. After quenching and tempering, it can improve hardness.5%, and sometimes also participates in appropriate amounts of [...]

It has a reddish rose color and is purple after forming an oxide film on the surface, so it is generally called red copper. The price of red copper is adjusted by the supply and demand of red copper. The relative density is 8.. The nature of red copper is named after its purple-red color. In the 1970s, the output value of red copper exceeded the total output value of other types of copper alloys. In addition, red copper has excellent weldability, and can be made into various semi-finished products and products by cold and thermoplastic.9, which is five times that of magnesium.

It is copper containing certain oxygen, so it is also called oxygen-containing copper. Red copper has excellent corrosion resistance in the atmosphere, sea water and certain non-oxidizing acids, [...]
