Characteristics of aluminum alloy door and window profiles？
Aluminum alloy profiles are profiles with aluminum as the main component and some alloy elements added to enhance strength and hardness.
According to chemical composition, aluminum alloy can be divided into aluminum-silicon alloy, aluminum-copper alloy, aluminum-magnesium alloy, aluminum-titanium alloy, aluminum-zinc alloy and aluminum-rare earth alloy. Generally, the raw material alloy is aluminum ingot, which is melted into aluminum bars and then extruded into aluminum bars for doors and windows by heating. It is not easy to oxidize and rust at normal temperature, but it will react with hydrogen after a long time of use. In order to increase the service life, the surface needs to be sprayed with anti-oxidation treatment, and the service life of the processed aluminum alloy profile can reach more than 30 years.
