The fluidity of Al-Mn alloy was evaluated by a vertical suction fluidity measurement method. The fluidity measurement and microstructure analysis were carried out on Al-1, 1.5, 2, 3 and 5 mass % Mn alloys. The fluidity length of Al-Mn alloys increases in accordance with the temperature of the molten metal. The increase in the Mn additive content decreases the fluidity length of Al-Mn alloys. Al-1, 1.5, 2 and 3 mass % Mn alloys showed a gradual reduction of the fluidity length in accordance with the amount of the Mn additive content. However, 5 mass % Mn alloy showed a substantial drop in the fluidity. It is considered that skin formation solidification causes the flow cessation mechanism of Al-1, 1.5, 2 and 3 mass % Mn alloys. In the case of the 5 mass % Mn alloy, the cessation is caused by mushy solidification.
