Metal materials play an important role in China's national defense construction. The picture shows the J-15 plane taking off on the Liaoning ship. (1) aluminum alloy is used to manufacture aircraft shells. (1) aluminum alloy can be used to manufacture aircraft shells because of its high strength and light weight.

(2) The corrosion of steel is actually the result of interaction between iron, water and oxygen;

The main component of rust is iron oxide, which can react with dilute hydrochloric acid to form ferric chloride and water. The reaction equation is: Fe2O3+6HCL = 2fecl3+3H2O;

(3) Carbon monoxide reduces iron oxide to produce iron and carbon dioxide at high temperature. The chemical equation of the reaction is 3CO+Fe 2 O 3 at high temperature. 2Fe+3co2。

So the answer is: (1) high strength and light weight;

(2) Oxygen and water vapor, Fe2O3+6HCL = 2FeCl3+3H2O;

(3)3CO+Fe 2 O 3 high temperature. 2 Fe+3 Co2。
