Tin-brass belt is produced and processed into rings of tin-red copper

Tin copper refers to the copper basically added tin in copper zinc alloy. Tin brass belt in the water and sea surface such as corrosion resistance, usually tin bronze plate tin content is 1%, containing too much tin, reduce the plasti. deformation of aluminum alloy. According to the content of zinc in aluminum alloy, it can be divided into  tin brass strip and (+) tin brass strip. Two phase electric tin brass strips such as 75Cu-28Zn-1Sn have excellent physical properties.

The soft tensile strength is 300MPa, elongation is 65%, cold working characteristics are excellent, can bear hot tying and hot extrusion, but not hot punching and hot forging. High strength nickel-based alloy condensing tube widely used in ships and power plants. This kind of aluminum alloy has the tendency of stress corrosion cracking, so cold-worked pipe fittings must be quenched at ultra-low temperature to remove the ground stress. (+) tin copper, such as 63Cu-38Zn-1Sn, has excellent physical properties, soft tensile strength of 220MPa, tensile strength of 50%.

Carry out cold and hot working pressure production and processing, fast cutting, electric welding strong weldability, high corrosion resistance in the sea, suitable for ship parts, parts that touch the sea, car gasoline and other parts. Adding tin to copper can significantly enhance the temperature resistance of aluminum alloy, which is very much to improve the working ability of anti-sea erosion, so tin copper is known as "South Sea Fleet copper". Tin can be integrated into copper - based solid solution to strengthen the effect of solid solution.

However, with the increase of tin content, ductile r phase (CuZnSn chemical substance) will appear in aluminum alloy, which is adverse to the plastic deformation of aluminum alloy, so the tin content of tin brass belt is usually within the range of 0.6% ~ 1.6%. Tin brass belt has high compressive strength, high strength and strong solvent corrosion resistance. There are also drilling production processing of physical properties are more prominent.

The seamless air conditioning copper pipe made of tin brass belt is soft and has strong wear resistance. Copper seamless steel pipe can be used in heat exchanger and cooler, low temperature pipeline, deep sea transport pipe. Tin brass belt can be used for the manufacture of thick plate, bar, bar, pipe fittings, forging parts, etc. Copper in 63% ~ 66%, plastic deformation is strong, manufacturing breakdown voltage machines and equipment.
