电气元件伴随着电器向体积小、轻、薄、多元化方向的发展，由普通铝材转向PU、PET等涂层为绝缘材料冲制的环保新型电气元件。 重庆西南铝精密加工有限责任公司于2010年开始研发电气元件用涂层铝及铝合金材料，2011年批量向市场供货，改写了该产品只能靠进口的历史，填补了国内空白，起草了《电气元件涂层铝及铝合金带材》( GB/T33229- -2016 )国家标准。 With the development of small, light, thin and diversified electriccomponents, the common aluminum material has turned to the newenvironment-friendly electrical components, with PU and PET coatings asinsulating materials. Chongqing SWA Precision Processing Co., Ltd. has began to researchcoated aluminium and aluminium alloys for electical elements in 2010,supplied to the market in bulk in 2011, which has rewitten the history whichthis product can only rely on imports and flled the domestic blank. NationalStandards of Coated Aluminium and Aluminium Alloys for ElecticalElements (GB/ T33229 -2016) was drafted as well.
