6. Applications and characteristics of aluminum alloy foil/roll
Characteristics of aluminum foil:
In addition to its excellent electrical and thermal conductivity, aluminum foil also has the following characteristics:
1. Good corrosion resistance: The surface of aluminum foil is covered with an oxide layer, which can improve its corrosion resistance and extend its service life.
2. Strong heat insulation performance: The surface covering layer of aluminum foil can not only protect the metal itself from oxidation but also form a heat insulation effect to prevent internal temperature loss.
3. Strong plasticity: As a very thin metal product, aluminum foil has strong ductility and plasticity and can withstand various shapes and be used as a container.
4. Diversified specifications: Aluminum foil has a very wide range of specifications, and the thickness, width, and length can be adjusted to meet various needs.
Aluminum foil is widely used in many fields, the following are its main uses:
1. Packaging: Aluminum foil is most widely used in the food and pharmaceutical industries. As a hybrid material of adhesive paper and plastic bags, it can effectively protect the food, medicine, cosmetics, and other products inside and prevent external oxidation and pollution. In addition, aluminum foil can also be used as blister containers and plastic wrap for a higher degree of protection. 2. Kitchen: As a kitchen accessory, aluminum foil has a very wide range of uses. For example, it is used to package oil, meat, seafood, vegetables, and other ingredients to prevent oxidation and preserve freshness. Aluminum foil can be used to wrap ingredients and make delicious dishes such as pot-roasted meat and grilled fish. Use aluminum foil to create oven trays that are easier to clean and use.
3. Electronic products: Aluminum foil also plays an important role in the field of electronic products. It can be used as a covering material for circuit boards to protect them from electromagnetic interference and temperature rise. As well as electrodes in electronic devices such as capacitors, inductors, and electrolytic capacitors.
Aluminum foil preparation process
The preparation of aluminum foil mainly includes raw material preparation, smelting, casting, and rolling processes. First, aluminum materials with extremely high purity requirements are selected, then smelted, and the molten aluminum is quickly solidified through a quenching process to obtain a defect-free aluminum billet. Next, the aluminum billet is heated, rolled, and other processes to prepare an aluminum plate with a suitable thickness, and then further processed through cold rolling, color coating, and other processes to obtain aluminum foil.
Aluminum foil rolling process
The main process of aluminum foil is rolling, which is also the core process of aluminum foil processing. It is mainly divided into two types: cold rolling and hot rolling. Cold rolling refers to rolling at room temperature, and hot rolling refers to rolling at high temperature. Cold-rolled aluminum foil has better surface quality and dimensional accuracy, while hot-rolled aluminum foil has better mechanical properties.
Aluminum foil stretching process
The stretching process means that the aluminum foil is processed by stretching, stamping, and other processes after cooling so that it has better processing performance and finished product quality. During the stretching process, the aluminum foil needs to be preheated, then processed through the stretching or extrusion process of the mold, and finally made into aluminum foil products with specific shapes and sizes.
As an important metal material, aluminum foil plays an important role in many industries. Aluminum foil has become an indispensable and important accessory in modern life due to its versatility. It includes many characteristics such as good protection, insulation, anti-corrosion, isolation, protection, strong plasticity and closeness to environmental protection, etc., and has won the love and use of more and more people. In the future, aluminum foil will be used more deeply in many fields, bringing people a more exquisite and practical experience in using excipients.
