青铜--铜锡合金 （ 除了锌镍外，加人其他元素的台金均称青铜 ） 。具有杰出的耐磨性、力学功能、铸造功能和耐蚀性。合金中锡的含量通常不超越 l0 ％，过高则下降其塑性。除锡以外，锡青铜中通常富含少数的锌、铅、磷、镍等元素。锌能提凹凸锡青铜的力学性哉和流动性。铅能改进青铜的耐磨功能和可切削加工性，但却下降其力学功能。镍能进步青铜的耐性、硬度、耐磨性和流动性。
Special sheet metal processing in sheet metal processing we often use a material is copper, and we will explain the differences for these copper materials.
Pure copper, also known as red copper, is light rose or pale red. It looks like red and red when it forms copper oxide film.
Brass - Copper - zinc alloy. The color changes from yellow to yellow with the addition of zinc. The mechanical function of brass is higher than that of pure copper. It is not corroded in the usual condition and is not corroded. The plasticity is better. It is widely used in making various layout parts in the machinery industry.
Bronze - copper tin alloy (except for zinc and nickel, adding other elements of Taiwan gold is called bronze). It has excellent wear resistance, mechanical function, casting function and corrosion resistance. The content of tin in the alloy usually does not exceed l0%, but its plasticity decreases when it is too high. In addition to tin, tin bronze is usually rich in zinc, lead, phosphorus, nickel and other elements. Zinc can raise the mechanical properties and fluidity of attapulgite. Lead can improve the wearability and machinability of bronze, but it reduces its mechanical function. Nickel can improve the durability, hardness, abrasion resistance and fluidity of bronze.
Copper - copper nickel alloy. It is divided into copper nickel alloy and electrical copper nickel alloy. The layout of Cu Ni alloy has high mechanical function and good corrosion resistance. Electrical copper nickel alloys usually have exceptionally thermoelectric functions and are widely used in electrical skills. Industrial famous manganese copper, copper, copper is not the same manganese content of manganese copper, they are the production of fine electrical measurement instruments, rheostat, thermocouples, electric heaters and other short electrical materials.
