Technical Notes -AluminumGrain Structure : Aluminum Molecule is Face Centered Cubic (FCC) Structure. (Its atoms are located at center of its face.) When Molten Aluminum Starts solidifying FCC molecules form a group attached to each other with FCC structure bonding .

FCCEach group forms a single grain. In the grain strongest molecules lies at its boundary area.Because each grain contains different nos. of molecules so every grains size varies. Grain Size can be achieved up to 40 at lower side. For Deep Drawing quality sheet grain size should be less than 60 .Tuckers Solution (HCl-45% + HNO -15% + HF- 15%+ Water-25%) to Check Grain Size . This solution becomes stable for 24 Hrs. Never keep Tuckers Solution in Glass Container, Keep it in Plastic Containers Only. This solution should never come in direct contact with human body) Deep Drawing Al CirclePunchDdD/d > 2Important Notes: 3S Metals annealing should be very faster rate (EMT: 415C ~ 450C for 2 Min) Roll lubrication should be continuous (lubricant 2.5% Coconut Oil + Keroscene 97.5%)Lick- Up : During Rolling Process Metal Oxide Layer transfers on Roll, it is called Lick-Up.Pick-Up : Metal Oxide layer transferred on roll during lick-Up process, retransfers at new sheet during rolling, It is called Pick-UPTo counter Lick-up & Pick-Up Processes Hot Roll Brush is used, It is made of Nylon with Alumina Coating on It.Prestige & Hawkins use Alloy 8011 for Utensils manufacturing RM. It contains 0.60%~0.90% Fe & 0.6%~0.95% SiWebsite for Alloy Properties information : www.matweb.com
