Fe-Ni 合金复铝带是以铁镍定膨胀合金4J42合金钢带为基层,以硅铝合金带为复层,采用固相结合的方法,将单条或多条硅铝合金带等距离地压合在基层带上。该复合带具有较好的散热性、遮光性、封闭性和超声压焊性,还具有成本低、经济效益好的特点。用复铝管壳比用4J29合金镀镍或镀金管壳成本可降低30%左右。复铝带的用途很广,它是发展民用电子工业(如电视机、录音机、计算
Fe-Ni alloy complex aluminum ribbon is made of iron-nickel alloy expansion alloy 4J42 strip as the base, silicon-aluminum alloy strip as the composite layer, using solid-phase combination of single or multiple silicon aluminum alloy strip with equal pressure Together at the grassroots belt. The composite belt has good heat dissipation, light blocking, sealing and ultrasonic welding, but also has the advantages of low cost and good economic benefits. Complex aluminum tube shell than the use of 4J29 nickel-plated or gold-plated tube shell can reduce the cost of about 30%. Complex aluminum with a wide range of uses, it is the development of civilian electronics industry (such as television sets, tape recorders, computing
