用钢铜双层板材代替整体铜板,可以节约昂贵的铜材,而且抗拉、抗弯强度及耐磨性能都比铜板好。为了解决双层板的脱层问题,采用了填孔法熔铸,经在一台摩擦压力机上作轨道的滑块,使用了一年多,除了正常磨损外,未见脱层或剥落,效果良 The use of steel and copper double-layer sheet instead of the overall copper, you can save expensive copper, and tensile, bending strength and wear resistance are better than copper. In order to solve the delamination of double-deck board, using the hole filling method, by a friction press orbit slider, the use of more than a year, in addition to normal wear and tear, no delamination or peeling, the effect is good
