The Best Aluminum Alloy Raw Material For Household Foil
Household foil generally refers to aluminum foil, which is a metal foil with aluminum as the main component, with good ductility, keplastikan, rintangan kakisan dan kekonduksian. The main purpose of household foil is to package food, kalis lembapan, anti pengoksidaan, fresh-keeping, dan lain-lain., and it is widely used in daily life. Household foil needs to have good fresh-keeping performance, sealing performance and corrosion resistance. Household foil is mainly made of aluminum, and there are 1-8 series of aluminum alloys. What aluminum alloy is the best choice for household foil?
This article will tell you which aluminum alloy is the most suitable for household foil?
Antaranya 1000-8000 series aluminum alloys, the alloys commonly used as household foil materials are 3003, 8011, 8079 dan aloi lain. 3003 aloi is a Mn alloy containing 1.0%~1.5% Mn, 0.6% Dan, and a small amount of Fe, Cu and other elements. Ia mempunyai rintangan kakisan yang baik, formability and welding performance, and is widely used in the production of air conditioner radiators, fuel tanks, dan lain-lain.
8011 aloi is an Al-Fe-Si alloy containing 0.5%~0.9% Fe, 0.25% Si and a small amount of Cu, Mg and other elements. It has good toughness and ductility, and is suitable for making food packaging materials, containers, lids, dan lain-lain.
8079 aloi is an Al-Zn-Mg alloy containing 0.12%~0.15% Zn, 0.05% Mg and a small amount of Cu, Fe and other elements. It has high strength, high elastic modulus and good corrosion resistance, and is suitable for making various composite packaging materials.
Among these three alloys, 8011 aluminum foil is the most common raw material for household foil. aluminium 8011 foil has good toughness and ductility, and is easy to process and form. Pada masa yang sama, it also has strong insulation properties, and neither air nor light can penetrate, so it is very suitable for food packaging materials, such as aluminum foil lunch boxes, food preservation aluminum foil, dan lain-lain.
Household aluminium foil made of 8011 aluminium alloy has excellent properties. 8011 aluminium foil is a versatile and widely used material. 8011 aluminium alloy belongs to the 8xxx series, which are aluminium alloys containing other elements to improve strength, durability and performance. The main components of 8011 alloy are. Aluminium (Al): 97.5-98.5%, besi (Fe): 0.6-0.75%, silikon (Dan): ~0.5-0.8%, and also contains small amounts of copper, mangan, magnesium, zinc and titanium, biasanya kurang daripada 0.1%. This alloy composition gives alloy foil 8011 rintangan kakisan yang baik, formability and welding properties. It has higher strength than pure aluminium and good polishing properties, and can maintain a bright surface for a long time.
One of the key properties required for household foil is excellent formability. 8011 alloy can be easily rolled into very thin sheets without cracking or breaking, even when the foil is less than 0.01 mm thick. Its ductility and plasticity allow it to be folded or crumpled, making it ideal for packaging food.
Aluminum naturally forms a protective oxide layer that resists corrosion. This makes 8011 alloy an excellent choice for household foil as it prevents interaction with moisture, chemicals, and food. It ensures that the foil remains stable and is safe for contact with food.
The composition of the Aluminum 8011 foil alloy ensures that it is non-toxic and safe for contact with food. It does not react with most foods, which is crucial when used for cooking or storage.
Although thin and lightweight, aloi aluminium 8011 has significant strength and durability and can be used for a variety of purposes around the home. This makes it ideal for everyday tasks such as food packaging, memanggang, and storing leftovers.
One of the most important properties of household aluminum foil is its ability to act as a barrier against light, udara, lembapan, dan bakteria. 8011 alloy is highly impermeable to these elements, helping to preserve the freshness and quality of packaged foods.
Aluminum is an excellent conductor of heat, which makes 8011 alloy ideal for uses that require heat management, such as baking and cooking. It can withstand high temperatures without deforming or maintaining integrity.
Another advantage of 8011 alloy is that it is fully recyclable. This increases its appeal to environmentally conscious consumers and industries. The recycling process for aluminum is energy efficient, making it a sustainable choice.
