C75200 copper alloy

C75200 copper alloy copper alloy brass to zinc as the main element of the copper alloy, with a beautiful yellow, collectively referred to as brass. Cu-Zn binary alloy that ordinary brass, or a simple brass. More than triple brass said the complexity of special brass or brass. Less than 36% zinc brass alloy by solid solution, nickel as a main element of the copper alloy. Copper-nickel binary alloy that ordinary copper-nickel alloy; plus a copper-nickel alloy of manganese, iron, zinc, aluminum and other elements that complex copper-nickel alloy. Industrial copper-nickel alloy and electrical copper-nickel alloy structure is divided into two categories. The structure is characterized by a copper-nickel alloy mechanical properties and corrosion resistance, beautiful color. This copper-nickel alloy is widely used in the manufacture of precision machinery, optical components, chemical machinery and ship components. Electrical cupronickel generally have good thermoelectric properties. Manganin, constantan, test copper manganese content of manganese copper-nickel alloy, a manufacturer of precision electrical instruments, rheostats, precision resistors, strain gauges, thermocouples and materials used. Copper high-quality copper, high purity, fine organization, the oxygen content is very low. Nonporous, trachoma, loose, good conductivity for electricity etched mold, heat treatment process, the electrode had no direction, suitable for playing fine, fine playing. Reference parameters: cu≥99.95% o & lt; 003 Conductivity ≥57ms / m hardness ≥85.2hv Bronze Originally referred to the copper-tin alloy, brass, copper-nickel alloy after the addition of a copper alloy known as bronze, and often in front of the bronze name preceded The first major add elements. ﹑ Bronze casting performance minus good friction properties and good mechanical properties, suitable for the manufacture of bearings, worm gear, gear and so on. Lead bronze Copper alloy hydrant wrench is bearing modern engines and grinding material widely used. Aluminum bronze, high strength, wear resistance and corrosion resistance, high load for casting gear, bushings, marine propeller. / Phosphor bronze and high elastic limit, good conductivity, suitable for the manufacture of precision springs and electrical contact element, beryllium copper used to make coal, oil depots and other non-sparking tools. Beryllium copper is a supersaturated solid solution copper alloys, mechanical properties, physical properties, chemical properties and good corrosion resistance; powder metallurgy production of tungsten steel, high carbon steel, high temperature super-hard alloy die to be produced by electrical eclipse due to the common electrode wear big, slow, tungsten, copper is an ideal material. Classification ≥667mpa flexural strength copper alloys free copper alloy, there are three: ① Press alloy system divided by the alloy system divided into non-alloy of copper and copper alloy non-alloy copper, including high pure copper, tough pitch copper, deoxidized copper. , oxygen-free copper alloy, it is customary, it will be called the non-copper or copper alloy of copper, also known as copper, copper alloys and other copper alloys belong. The alloy of copper and Russia into brass, bronze and copper-nickel alloy, and then divide the small alloy system in major categories. ② by function by function, there is thermal conductivity copper alloy (as long as there is unalloyed copper and micro-alloying copper) structure with copper alloy (including almost all copper alloy) and corrosion of copper alloy (mainly tin brass , aluminum, brass, various non-nickel alloy, aluminum bronze, titanium, bronze, etc.) wear-resistant copper alloys (mainly lead, tin, aluminum, manganese and other elements of complex brass, aluminum, bronze, etc.), cutting copper alloy (copper - lead, copper - tellurium, copper - antimony alloy), flexible copper alloy (mainly antimony bronze, aluminum bronze, beryllium copper, titanium, bronze, etc.) damping copper alloys (high manganese-copper alloy, etc.), art copper alloy (copper, Simple single copper, bronze, aluminum bronze, copper-nickel alloy, etc.). Obviously, many copper alloys have to have more functionality. ③ According to the material is divided according to the method for forming the material into forming method for cast copper alloy and copper alloy deformation. In fact, many copper alloys can be used either copper alloy casting, and can be used for deformation processing. Usually deformed copper alloys can be used for casting, many cast copper alloys can not be forged, extrusion, deep drawing and drawing and other deformation processing. Cast copper alloy and copper alloy deformation can be subdivided into casting copper, brass, bronze and copper-nickel alloy.
