The invention belongs to the technical field of machining, and particularly relates to a punching method of a low-plasticity high-silicon aluminum alloy strip. The punching method includes the steps:heating the high-silicon aluminum alloy strip to reach the temperature of 200-350 DEG C, and punching the heated high-silicon aluminum alloy strip; designing the depth of a punching die guide groove to account for 30%-70% of the thickness t of the high-silicon aluminum alloy strip, designing the gap between a punched female die and a punched male die to be 12-15% t, and designing the bottom of a punched die cutting edge into a round angle with the radius r of 0.2-0.5mm. By the punching method, punching effect with high-accuracy cross section quality can be acquired, punching efficiency is improved, the service life of a punching die is prolonged, and production cost is reduced.
