What is the chemical formula for aluminum alloy?
Aluminum can be quantitatively analyzed as the oxide (formula Al2O3) or as a derivative of the organic nitrogen compound 8-hydroxyquinoline. The derivative has the molecular formula Al(C9H6ON)3.
What are the 2 classifications of aluminum alloys?
There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions.
What are the grades of aluminum?
Different Aluminum Grades Aluminum comes in three basic types: 1100, 3003, and 6061. The grade of the aluminum will determine the end-use application and price point. For example, 1100 is a lower-cost material than 6061 but cannot be used for high-temperature applications like cooking utensils or pot lids.
What is the compound for Al2O3?
Al₂O₃Aluminium oxide / Formula
What is the composition of 355 CR aluminum?
Among cast aluminum alloys, the composition of 355.0 aluminum is notable for including chromium (Cr). Chromium is used to limit grain growth during hot working or heat treatment, which improves ductility and toughness. Chromium also reduces the alloy’s susceptibility to stress corrosion cracking.
What is the difference between 355 and A356 aluminum alloy?
The 355 aluminum alloy is great for pressure tight applications and the alloy also maintains its strength at higher temperatures than A356. The trade off is typically C355.2 is more expensive than 355.1.
What is 355 aluminum sand casting alloy used for?
Aluminum sand casting alloy 355 uses copper to greatly improve its strength over the more common aluminum casting alloy A356. The 355 aluminum alloy is great for pressure tight applications and the alloy also maintains its strength at higher temperatures than A356.
What is a03550 aluminum?
355.0 aluminum is an aluminum alloy formulated for casting. 355.0 is the Aluminum Association (AA) designation for this material. A03550 is the UNS number. Additionally, the SAE designation is 322. The British Standard (BS) designation is LM16. And the AFNOR (French) designation is A-S4UG.
