Oxidation process of aluminum alloy nut

The invention discloses an oxidation process of an aluminum alloy nut. The oxidation process comprises the following steps of pre-cleaning, weak base oil removal, alkali corrosion, neutralization, oxidation, baking and color fixation, hole sealing, drying and packaging. The surface of the nut is subjected to oxidation and color plating treatment, the durability of the nut is prolonged, and the durability of equipment such as air conditioners is effectively prolonged; meanwhile, the aluminum alloy nut is used, the specific gravity is smaller than that of a durable copper nut, and the weight of the whole connecting structure is reduced; and the cost is low and effectively reduced. 本发明公开了一种铝合金螺母的氧化工艺，工艺步骤流程如下：预清洗-弱碱除油-碱蚀-中和-氧化-烘烤固色-封孔-烘干-包装；本发明对螺母表面进行氧化镀色处理，延长了螺母的耐久性，有效延长空调等设备的耐久性；同时使用铝合金螺母，比重小于耐用的铜制螺母，使整体连接结构的重量减轻；成本低廉，有效降低成本。
