Heimilispappír, einnig kölluð heimilisálpappír og almennt nefndur álpappír, er þunn álplata sem notuð er til ýmissa heimilisnota. Það er orðið nauðsyn fyrir mörg heimili vegna fjölhæfni þess, endingu, og þægindi.
Álpappír til heimilisnota er venjulega úr álblöndu, 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 álblöndu.
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. Tæringarþol: 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. Óeitrað og öruggt: It is non-toxic and safe for food use.
8011 aluminum alloy usually includes: – **Ál (Al)**: 97.5% – 99% – **Járn (Fe)**: 0.6% – 1% – **Kísill (Og)**: 0.5% – 0.9% – **Other elements**: small amounts of elements such as manganese (Mn), kopar (Cu), zinc (Zn) and magnesium (Mg).
These characteristics and composition make 8011 aluminum alloy the most suitable choice for household aluminum foil.
