Material: Aluminium foil
I . About Aluminum :
Aluminum is a Period 3 metal that exists as a solid at room temperature . The element is atomic number 13 , with an atomic mass of 26.98 . Aluminum's melting point is 1,220 degrees Fahrenheit , and its boiling point is 4,566 degrees Fahrenheit . In its solid phase , aluminum has a density of 2.7 grams per cubic centimeter , though its low density does not significantly impact its strength .
Unlike steel alloys , aluminum does not become brittle at low temperatures . Instead , pure aluminum and many of its alloys become stronger at low temperatures . At temperatures over 212 degrees Fahrenheit , aluminum softens and weakens significantly as a load-bearing material . Aluminum is easy to work with , as it responds well to most forms of machining with very little energy input .
Aluminum is an excellent conductor of both heat and electricity . Pure aluminum has an electrical conductivity similar to that of copper but at only half of copper's weight . It is also a good reflector of visible light and radiated heat , which makes it useful as a wrap for food .
II . Cold rolling Aluminum management
Dilly Family does not only promise quality of final product , but also focus on the quality of raw material . And the raw material we use should own the following characteristics :
- Chemical composition :
| Alloy | Si | Fe | Cu | Mn | Mg | Cr | Zn | Ti | Others | Al | Remark | |
| Per unit | Total | |||||||||||
| 8011A | 0.40-0.8 | 0.5-1.0 | 0.1 | 0.1 | 0.1 | 0.1 | 0.1 | 0.05 | 0.05 | 0.15 | Balance | |
| Note: The essence with upper and lower limits is alloy element. If the element is an odd number , for Aluminum it is the lowest limit, for other element the top limit . | ||||||||||||
| For the chemical composition ,the poisonous should comply the regulation of the following | ||||||||||||
| one and GB 11333 . Pb≤0.01% , Cd≤0.01% , As≤0.01% . | ||||||||||||
- Mechanical performance :
| Alloy | Temper | Thickness mm | Mechanical performance | |
| Tensile (σb, Mpa) | Elongation(δ,% ) | |||
| 8011 | O | 0.009-0.018 | (60-100) | ≥1 |
- Wettability :
Surface of O temper should be no oil or oil blisters. The wettability should be above B grade or determined by the negotiation of both sides .
- Web :
Foil coil should entwine properly . Transection should be flat and clean , with smooth edge, and without defects of serious burr , arrow , pyramid , which can affect usage . The telescoping isn't allowed above ±1mm .
- Surface :
The surface should be clean and flat with no defects such as corrosive stain , slit , wrinkle & bruise , which can affect usage . But it's allowable to keep the ripple mark and impress nick on the surface if they have no effect on usage .
III . Aluminum foil in Kitchen use:
The physical characteristics makes Aluminum foil an essential material for household use :
- Aluminum foil is an excellent conductor of heat and can withstand the highest temperatures encountered in cooking ;
- Aluminum foil has unique mechanical properties as it is formable , strong and can be ‘ dead folded ’ , which is beneficial when wrapping food ;
- Aluminum foil provides a total barrier to light , odor and moisture , thus making it ideal for the protection of sensitive food during cooking and storage ;
- After it has been used , Aluminum foil can be recycled or recovered in the form of energy .
Because of these above unique and versatile properties , Aluminum foil becomes the best helper in household wrapping .
IV . Aluminum foil Vs Plastic in household :
Comparing the plastic film , as the household kitchen use material , Aluminum foil has its own
property :
| Kitchen material | Advantages | Disadvantages |
| Foil | 1) Ideal for wrapping odiferous foods 2) Can be heated in the oven 3) Can be used in roasting 4) Environment friendly material 5) Can be 100% recyclable 6) Can be used when polishing silver | 1) can not be used in the microwave 2) Not suit for wrapping acidic foods, like tomatoes and berries , in foil. The acids react with the aluminum , leaving a harmless but unsightly blue residue . |
| Plastic | 1)Can be microwaved, but needs at least an inch away from food as the heat from the food can cause the plastic to melt . 2) Can wrap acidic foods . | 1) Can not be used in the oven 2) Not good like Foil when freezing 3) Can not be used when roasting 4) Lead to Environment pollution 5) Less than 30% recyclable |
