异形钣金加工的常用材料有那些?

异形钣金加工阐述在钣金加工中我们经常能用到一种材料就是铜,下面我们就针对这几张铜质材料的不同来为大家讲解下。

纯铜--也称红铜呈浅玫瑰色或淡赤色,外表构成氧化铜膜后,外观呈紫赤色。

黄铜--铜锌合金。色彩随含锌量的添加而由黄赤色变到谈黄色。黄铜力学功能比纯铜高,在通常状况下不生锈也不会被腐蚀;塑性较好,被广泛用于机械制作业中制作各种布局零件。

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。

白铜--铜镍合金。分为布局铜镍合金和电工铜镍合金。布局铜镍合金力学功能高,耐蚀性较好。电工铜镍合金通常具有格外的热电功能,在电工技能中有着广泛的使用。工业上有名的锰铜、康铜、考铜即是不一样含锰量的锰白铜,它们是制作精细电工丈量仪器、变阻器、热电偶、电热器等不行短少的电工材料。

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.
