The invention belongs to the field of new material communication equipment, and particularly relates to an aluminum alloy communication tower. The aluminum alloy communication tower comprises a towerbody. The tower body comprises a plurality of sections of tower main bodies. Each section of tower main body is provided with a pulley. The pulleys are connected through a steel wire rope. The steel wire rope is connected with an electromotor. The electromotor drives the steel wire rope to pull the tower body to rise and fall. The electromotor is connected with a PLC. The PLC is connected with a seisesthesia detector. The tower body is made of an aluminum alloy. The aluminum alloy comprises the following components of, by weight, 0.1-0.2% of iron, 0.1-0.2% of copper, 0.05-0.1% of manganese, 0.3-0.6% of magnesium, 0.01-0.05% of chromium, 0.1-0.5% of zinc, 3-8% of nickel, 0.1-0.2% of nanometer titanium dioxide, 0.1-0.3% of nanometer silicon carbide, 1-3% of graphene, and the balance aluminum. According to the aluminum alloy communication tower, the tower body is made of the modified aluminum alloy, stress is stable, the structure is uniform, the density is small, construction is convenient, anti-corrosion performance is good, and the maintenance cost is low.
