该合金主要用来制作低速重载轴瓦或轴套,与硬轴匹配使用,也适用于制作镶片之类的磨损件,以代替常用的青铜件。该合金以锌——铝系为基,加少量合金元素,使在基体上分布硬质点,软相数量不低于10%,控制质点的大小,形貌和分布。用电阻炉熔炼。金属型、砂型或离心铸造成形,或等温挤压成型。合金摩擦系数、磨轴量与ZQSn6—6—3青铜相当或略低、耐磨性高2～4,成本不到青铜的1/2,无污染,易切削,能耗低,适宜于单件和批量生产。 The alloy is mainly used to make low-speed heavy-duty bearing bushings or bushings, matched with the hard axis, but also suitable for making inserts and the like wear parts instead of the commonly used bronze pieces. The alloy with zinc - aluminum-based, plus a small amount of alloying elements, the distribution of hard points on the matrix, the soft phase number of not less than 10%, controlling the size, morphology and distribution of particles. Resistance furnace smelting. Metal, sand or centrifugal casting forming, or isothermal extrusion molding. Alloy friction coefficient, grinding amount and ZQSn6-6-3 bronze equivalent or slightly lower, high wear resistance 2 to 4, the cost of bronze 1/2, pollution-free, easy cutting, low energy consumption, suitable for a single And mass production.
