Kerajang isi rumah, juga dipanggil kerajang aluminium isi rumah dan biasanya dirujuk sebagai kerajang aluminium, ialah kepingan aluminium nipis yang digunakan untuk pelbagai tujuan isi rumah. Ia telah menjadi keperluan untuk banyak isi rumah kerana serba boleh, ketahanan, dan kemudahan.
Kerajang aluminium isi rumah biasanya diperbuat daripada aloi aluminium, 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 aloi aluminium.
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. Rintangan kakisan: 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. Tidak toksik dan selamat: It is non-toxic and safe for food use.
8011 aluminum alloy usually includes: – **aluminium (Al)**: 97.5% – 99% – **besi (Fe)**: 0.6% – 1% – **silikon (Dan)**: 0.5% – 0.9% – **Other elements**: small amounts of elements such as manganese (Mn), tembaga (Cu), zinc (Zn) and magnesium (Mg).
These characteristics and composition make 8011 aluminum alloy the most suitable choice for household aluminum foil.
