Industrial Aluminium Foil 3003 8011
Aluminum and aluminum alloys can be smelted in various ways. Commonly used are coreless induction furnaces and trough induction furnaces, crucible furnaces and reflex open hearth furnaces (burning with natural gas or fuel oil), resistance furnaces and electric radiant furnaces. There are a wide range of charge, from high-quality pre-alloyed ingots to charge made of low-grade scrap. However, even under the most suitable conditions for smelting and pouring, molten aluminum is susceptible to three types of adverse effects:
Under high temperature conditions, over time, the adsorption of hydrogen leads to an increase in hydrogen dissolved in the melt.
Under high temperature conditions, as time goes by, the melt is oxidized.
In the past, the decompression test method has been used to measure the amount of hydrogen dissolved in the melt. The process is to inject a sample of molten aluminum into a steel cup and let it solidify in a vacuum chamber. Observing the solidification process, it is found that the degree of bubble change during the solidification process indicates the amount of hydrogen present. At the same time, the solidified sample section can be used to check the size of the bubbles formed. Unfortunately, these methods are not accurate and are greatly affected by the presence of oxide particles in the melt as nuclei of hydrogen bubbles. A better way to test dissolved hydrogen is to use a specially designed instrument that uses liquid extraction technology to display hydrogen.
3003 aluminum foil is used for processing parts that require good forming properties, high corrosion resistance and good weldability, or work that requires these properties and higher strength than 1XXX series alloys, such as kitchenware, food and chemical products Processing and storage devices, tanks and tanks for transporting liquid products, various pressure vessels and pipes made of thin plates.
