3004 aluminum foil is a kind of adding the strengthening element magnesium. It not only has the advantages of 3003 alloy, but also has higher strength than 3003 alloy. It also has good formability, solubility and corrosion resistance. What are its popular uses?
Aluminum foil container is made of aluminum foil with certain strength and toughness after stamping and forming. It is a new type of food and beverage packaging and distribution container, featuring moisture-proof and anti-corrosion, and long shelf life. At the same time, because aluminum can better maintain the freshness and moisture of food, it is more in line with modern people's concept of environmental protection and healthy life.
3004 aluminum foil is 3xxx hot rolled aluminum foil, with high hardness, good load-bearing, better stamping effect than 3003 aluminum foil. On the basis of ensuring the low price of 8011 alloy, the aluminum foil tray made by 3004 alloy also ensures the high strength of 3003 alloy, and the strength is higher than that of 3003 alloy. It can be said that it has both the price advantage of 8011 and the strength advantage of 3003.
It is he main material used to make aluminum honeycomb cores. As an important raw material of honeycomb core, aluminum foil has a great influence on the quality and service life of honeycomb core. The alloy used is generally 3004 aluminum foil with H18 temper. The thickness is between 0.03-0.08mm. there are also a few 5052 honeycomb aluminum foil, but because it is of high cost, it is less used than aluminum foil.
Aluminum foil is widely used in flexible packaging. Due to its low strength, it is easy to break at the beginning of folding, so it is rarely used alone. It is generally composited with paper, cellophane or polyethylene film.
The air-conditioning foil substrate can be made of 1100/3003/3004/8011 alloy, etc., and there is no strict requirement on the chemical composition of the material. AA 3004 aluminum used for the heat-conducting fin material of the air-conditioning heat exchanger belongs to the aluminum-manganese alloy, which has good corrosion resistance, excellent formability, high strength and elongation, and meets the mechanical performance requirements of the air-conditioning foil.
