作为资源、基础材料开发的我国有色金属工业,除部分骨干企业技术装备水平接近或达到国际先进水平外(占总产能不足20％),大多数中小企业技术和装备水平还相当落后。我国一般冶炼产品、初级加工产品供过于求,高新技术产品、材料短缺,如高精度铝板带、高档铝箔、大规格铝合金材、电子铜箔、引线框架 As a resource and basic material development, China’s non-ferrous metal industry, with the exception of some backbone enterprises whose technological equipment levels are close to or reach the international advanced level (accounting for less than 20% of the total production capacity), still lags behind most of SMEs in technology and equipment. China’s general smelting products, primary products oversupply, high-tech products, materials shortage, such as high-precision aluminum plate, high-grade aluminum foil, large aluminum alloy, electronic copper foil, lead frame
