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
