What are the characteristics of aluminum alloy doors and windows? What are the characteristics of the profile?
(1) During the production process of doors and windows, manufacturers will also use surface treatment methods such as oxidation, electrophoresis, porcelain swimming, powder spraying, fluorocarbon, wood grain transfer, etc. Service life of doors and windows.
(2) Aluminum alloy profiles are profiles that are mainly made of aluminum and some alloying elements are added to enhance the strength and hardness.
Aluminum alloys can be divided into aluminum-silicon alloys, aluminum-copper alloys, aluminum-magnesium alloys, aluminum-titanium alloys, aluminum-zinc alloys and aluminum-rare earth alloys according to their chemical composition. Generally, the raw material alloy is aluminum ingot. After the aluminum ingot is melted into an aluminum rod, it is extruded into aluminum bars for doors and windows by heating.
It is not easy to oxidize and rust at room temperature, but it will react with hydrogen after a long time of use. In order to increase the service life, it is necessary to carry out surface spraying and anti-oxidation treatment. The service life of the processed aluminum alloy profiles can reach more than 30 years.
