To study the influences of extrusion temperature on properties of new type aluminium alloy 6061-InTi for architectural decoration, the alloy specimens were extruded at different extrusion temperatures, the Charpy pendulum impact test and the neutral salt spray corrosion test of specimens were conducted at room temperature, and the influences of extrusion temperature on the impact and corrosion resistance properties of alloy specimens were analyzed. The results show that with the increasing of extrusion temperature, the impact absorption energy of specimen increases first and then decreases slowly, the mass loss per unit area decreases first and then increases slowly, and the impact property and the corrosion resistance property both increase and then decrease. Compared with the extrusion temperature of 400 ℃, the impact absorption energy increases by 32.65% and the mass loss per unit area decreases by 40.58% at the extrusion temperature of 460 ℃ in the condition of the extrusion speed of 3 m·min-1, the die preheating temperature of 280 ℃ and the extrusion rate of 25. Thus, the optimized extrusion temperature of new type aluminium alloy 6061-InTi for architectural decoration is 460 ℃.
