Corrosion properties of aluminum
Aluminum is distinguished by high corrosion resistance against aggressive media such as
Sulphurous gas, hydrogen sulphide, ammonia and other gases. Even at elevated temperatures, the metal does not corrode in water, is resistant to the effects of water vapor. However, with the increase in the amount of cations in the water, the corrosion of aluminum is accelerated.
Of the various elements and compounds, copper, mercury and chlorine most actively accelerate the corrosion of aluminum. These chemical elements, as well as their compounds, contribute to the destruction of the surface film from aluminum dioxide, which serves as a protection against penetration of corrosion activators into the metal.
The company Aluminum in any assortment is offered by Electrovek-Steel. Products are sold at prices from the manufacturer and delivered by the supplier to any address that the client establishes.
