The main element of aluminum magnesium alloy aluminum plate is aluminum, and then a small amount of magnesium or other metal materials are added to strengthen its hardness. Aluminum alloy with Mg as the main additive element is also called antirust aluminum alloy because of its good corrosion resistance. Because it is a metal, its thermal conductivity and strength are particularly prominent.
8021-0 aluminum foil has great advantages in physical properties. 8021-0 aluminum foil gives full play to the properties and advantages of aluminum. We know that pure aluminum is easy to oxidize, so 8021-0 aluminum foil will form a dense oxide film on its surface. Don't underestimate this oxide film, which helps 8021-0 aluminum foil completely destroy the non rust resistance of iron sheet. 8021-0 aluminum foil has high plasticity and is widely used in insulation room. In addition, the appearance of aluminum sheet is neat, smooth and beautiful. It not only gives people visual enjoyment, but also achieves the effect of rust prevention, waterproof and thermal insulation in performance. Although 8021-0 aluminum foil is not familiar, any experienced expert will make good use of 8021-0 aluminum foil to achieve the purpose of high quality and low price. 8021-0 aluminum foil has high value and can meet the requirements of many special occasions. It is widely used in housing construction and pipe making materials. Later, when selecting 8021-0 aluminum foil, we need to pay attention to the color of 8021-0 aluminum foil.
Performance introduction of 8021-o aluminum foil:
(1) The surface is clean and sanitary, and no bacteria or microorganisms can grow on its surface.
(2) 8021-o aluminum foil is a non-toxic packaging material. It can be in direct contact with food without any danger to human health.
(3) 8021-o aluminum foil is a tasteless and odorless packaging material, which will not make the packaged food have any peculiar smell.
(4) No matter at high temperature or low temperature, 8021-o aluminum foil will not have grease penetration.
(5) 8021-o aluminum foil has high hardness and tensile strength, but its tear strength is small, so it is easy to tear.
(6) 8021-o aluminum foil is an opaque packaging material, so it is a good packaging material for products exposed to sunlight, such as margarine.
(7) 8021-o aluminum foil has good plasticity, so it can be used to package products of various shapes. It can also create containers of various shapes.
The plain aluminum foil material of 8021 has good performance and extensibility. Generally, the common thickness is 0.04mm. The main advantage is that it is used in deep drawing packaging materials. Soft pack battery has the following advantages:
High energy density. The general 18650 battery capacity can reach about 2200mAh, so the energy density is about 500wh / L, while the energy density of polymer battery can be close to 600wh / L at this stage.
Good security. Polymer batteries do not have this problem. Even in the same case, due to the low strength of the packaging film, it will break as long as the air pressure is slightly higher, and there will be no explosion. The bad situation is combustion.
