作为电缆线芯用的铜、铝、铝合金,一般来讲,其抗腐蚀性应为铜好于铝及铝合金,但务必,电缆线芯用的铜线,如果绝缘材料中有硫,则铜表面就会产生“发粘发黑”的腐蚀产物。因而铜线表面要镀一层锡,究其原因就是要使锡起到的作用;铜包铝线的抗腐蚀性,万一铜表面出现“”(露铝),将产生加快的电化腐蚀,因而导致脆断。0CrNi2Si2MoV,4340,SNCM439,40CrNiMoA,20CrNi2Mo ,20CrMnMo ,40CrMnMo ,35CrMo ,42CrMo,4140,4130,SAE8620,45CrNiMoVA,16MnCr5,15CrMn,38CrMoAlA,20MnCr5,20CrMn,18Cr2Ni4WA ,12CrNi3,20Cr2Ni4A ,35CrMnSiA,30CrMnSiA,18CrNi3Mo,25Cr2MoV,22CrMoH,20CrMnMo,20CrMnTi,30CrMnTi,25CrNiMoV,20CrNiMo,G20CrNi2Mo,30Cr2Ni2Mo,17Cr2Ni2Mo,17CrNiMo6,18CrNiMo7,34CrNiMo6,30CrNiMo8,40CrNi。45CrNi,20Ni4Mo,20CrMnSiNi2A,30CrMnSiNi2A,38CrSi,34CrNi1Mo,12CrNi3A,20CrNi 30CrNi3A,34CrNi3A,37CrNi3A,34CrNi3MoA,37CrNi3MoA,12Cr2Ni4A,20Cr2Ni4A,18Cr2Ni4W,25Cr2Ni4W,25Cr2MoV,25Cr2Mo1V,12CrMo,12Cr1MoV,35CrMoV,45Cr2MoV,18CrNi3MoA,20CrNi3MoA,25CrNi3MoA,,22SiMnCrNi2MoVA,5CrW2Si辽宁辽阳积压回收电缆库存回收电缆价钱是多少一吨
