前言家庭用铝制品俗名钢精制品,一般由纯铝板材冲压而成。由于铝的比重小,导热性能好,其制成品有蒸煮食物速度快、省时、省燃料和使用轻便等优点,因而受到广大用户的喜爱。但是,纯铝的强度较低,抗腐蚀性能、特别是耐低浓度酸、碱、盐的能力不强,影响了制品的使用寿命。为了解决纯铝制品使用寿命不长的问题,铝制品行业都致 Preface Family aluminum products commonly known as refined steel products, generally made of pure aluminum sheet stamping. Due to the small proportion of aluminum, good thermal conductivity, the finished product has the advantages of fast food cooking speed, time saving, fuel saving and ease of use, which are subject to the majority of users. However, the lower the strength of pure aluminum, anti-corrosion properties, especially resistance to low concentrations of acid, alkali, salt is not strong, affecting the service life of products. In order to solve the problem of short service life of pure aluminum products, aluminum products industry have caused
