treatment of aluminium alloy, and surface treatment of the aluminium alloy. The lected aluminium alloy (11) is subjected to mechanical machining to form an aluminium alloy rough blank (21). The formed aluminium alloy rough blank (21) is subjected to fine shaping and machining to obtain the required dimensions and shape of an outer profile of a water tap water-control spool (60), forming an aluminium alloy machined article (31). Then the aluminium alloy machined article (31) is subjected to a heat treatment to form a mi-finished article of a spool. Finally, the mi-finished article of a spool is subjected to an aluminium alloy surface treatment, forming a surface-hardened layer (61) on the spool surface, to obtain a finished product of the water tap water-control spool (60). The strength, hardness and wear-resistance of the water tap water-control spool (60) manufactured by this method are all improved, resulting in an incread rvice life of the spool, decread material costs, and a lightening in the weight of the product.
