　　公司主要产品—pol metal 铜包铝线和铜包钢线，采用先进的包覆焊接制造术，将高品质铜带同心地包覆在铝杆或钢丝等芯线的外表面，并使铜层和芯线之间形成牢固的原子间的冶金结合。使两种不同的金属材料结合成为不可分割的整体，可以象加工单一金属丝那样作拉拔和退火处理，拉拔过程中铜和铝（钢）同比例的变径，铜层体积比则保持相对恒定不变。
  由于高频信号具有“趋肤效应”的特点，因此铜包铝线和铜包钢线在传输高频信号（大于5MHz）时，具有与纯铜线相同的导电性能。

PRODUCT

  Our leading  bimetallic products are  pol metal CCA wire and CCS  wire .By applying  our patented clad-welding technique, the wire is made by fusing a core aluminum or steel wire with an external copper cladding .The two different kinds of metals are metallurgically bonded at their interface and the copper-cladding thickness remains constant,so they become a single and indissociable wire.
  Because of skin effect,the AC conductivity of CCA and CCS wire equals to solid copper when frequency greater than 5 MHz
