Cov ntawv ci hauv tsev, tseem hu ua tsev neeg aluminium ntawv ci thiab feem ntau hu ua aluminium foil, yog ib daim ntawv nyias ntawm txhuas siv rau ntau yam hauv tsev. Nws tau dhau los ua qhov yuav tsum muaj rau ntau tsev neeg vim nws muaj ntau yam, durability, thiab yooj yim.
Cov ntawv txhuas hauv tsev feem ntau yog ua los ntawm aluminium alloy, which combines the characteristics of pure aluminum with the advantages of additional elements to improve functionality. The most commonly used alloy for household aluminum foil is 8011 aluminium alloy.
1. Good formability: 8011 aluminum alloy has excellent formability, which can be rolled into very thin sheets, which is essential for aluminum foil applications. 2. Corrosion kuj: This alloy has strong corrosion resistance, which is important for food storage and packaging. 3. High ductility: 8011 alloy has high ductility, making it easy to form and wrap around various objects. 4. Heat resistance: It can withstand high temperatures and is suitable for cooking applications such as baking and grilling. 5. Non-toxic and safe: It is non-toxic and safe for food use.
8011 aluminum alloy usually includes: – **Aluminium (Al)**: 97.5% – 99% – **Hlau (Fe)**: 0.6% – 1% – **Silicon (Thiab)**: 0.5% – 0.9% – **Other elements**: small amounts of elements such as manganese (Mn), tooj liab (Cu), zinc (Zn) and magnesium (Mg).
These characteristics and composition make 8011 aluminum alloy the most suitable choice for household aluminum foil.
