Red copper bar shape processing

Copper bar is actually the form of copper distribution, there are many kinds. With excellent performance, red copper is an ideal substitute material for circuit breaker, contact conductive plate, low voltage air switch conductive metalware, etc. The microstructure of the product has good grain refinement, and the tensile strength of the product is increased by 10% compared with that of pure copper bar. 4%, how much is the carrying capacity of the copper row, hardness increases by 3%, the production process of the copper row, the conductivity of the copper row increases by 4. Compared with imported alloy, the wear resistance is improved by 2.8 percentage points. Making electrical accessories with materials can improve the quality grade, prolong the service life of products and ensure public safety. Red copper row, a kind of non-ferrous metal pipe, is a kind of seamless tube that is pressed and drawn. Red copper row light weight, good thermal conductivity, high low temperature strength. It is often used to manufacture heat exchange equipment (such as condensers, etc.). It is also used to assemble low-temperature pipes in oxygen production equipment. Small diameter copper rods are often used for conveying liquids under pressure (such as lubricating systems, oil pressure systems, etc.). And pressure gauge tubes used as instruments. Red copper row is extruded from oxygen-free copper rod, which has good processing characteristics and can meet the requirements of stamping, bending and forming. The surface can be treated with corrosion protection such as nickel, tin and zinc plating. The corrosion resistance of nickel coating can reach 72 hours of fog test. Surface tin plating for environmental protection lead-free tin, tin surface support welding. Copper has fine microstructure and low oxygen content. Especially in porosity, monomer sand, porosity and electrical conductivity, electroetching die surface precision is high, after heat treatment electrode has no direction, suitable for sagging and fine beating, with good thermoelectric, machining, ductility, corrosion resistance and weather resistance. Moulded copper can be widely used in electrical appliances, steam distillation construction and chemical industry, especially for terminal printed circuit boards, copper tape for wire shielding, air cushion and bus terminals. Electromagnetic switch, pen holder, roof board, etc. If the storage conditions of the mold copper are not high, it should be stored in a cool and ventilated place, not in contact with acid and alkali corrosive substances, or coated with anti-rust oil.
