A method of forming a hypoeutectic aluminium silicon alloy including the steps of: forming an aluminium melt including greater than zero and less than about 12 wt % silicon, adding 20-3000 ppm of a eutectic modifying element selected from the group consisting of strontium, sodium, antimony, barium, calcium, yttrium, lithium, potassium, ytterbium, europium and mischmetal; and either adding nucleant particles and/or causing nucleant particles to be formed in the melt, the nucleant particles being selected from the group of TiSix, MnCx, AlP, AlBx and CrBx wherein x is an integer of 1 or 2.
