The combustion characteristics of Al?CuO thermite with different sizes of Al particles were studied at different equivalence ratios (φ) by a homemade ignition apparatus. The results showed that the flame propagation rates of all samples trended down with increasing of the equivalence ratio. However, at the same mass ratio of Al to CuO, if φ>1.5, the flame propagation rates increased with the decreasing of Al particle sizes, if φ<1.5, the flame propagation rates increased with the increasing of Al particle size. The reaction of Al and CuO became more intense with the decreasing of equivalence ratio. When the mass ratio of Al to CuO was 50:50, the peak temperature of the samples ascended with the increasing of Al particle size.
