電氣元件伴隨著電器向體積小、輕、薄、多元化方向的發展，由普通鋁材轉向PU、PET等涂層為絕緣材料沖制的環保新型電氣元件。 重慶西南鋁精密加工有限責任公司于2010年開始研發電氣元件用涂層鋁及鋁合金材料，2011年批量向市場供貨，改寫了該產品只能靠進口的歷史，填補了國內空白，起草了《電氣元件涂層鋁及鋁合金帶材》( GB/T33229- -2016 )國家標準。 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.
