7068 alloy is a 7000 series aluminium-zinc alloy registered with the US Aluminium Association and produced to AMS 4331 (chemical composition and mechanical properties) and AMS 2772 (heat treatment). 7068 alloy ‘A’ and ‘B’ tensile data and fatigue properties have been ratified for inclusion in MIL Handbook 5 / MMPDS.
The process of hot dipping starts by cleaning the steel, then placing the steel in a bath of Al-11%Si at a temperature of 988K and shaken, then pulled out and air dried. [5] The aluminium diffuses into the steel, creating an intermetallic layer above the steel base layer, but below the outside aluminum coating.
The seasoned surface will deteriorate at the temperature where the coating breaks down. This is typically higher than the smoke point of the original oils and fats used to season the cookware. Thus old seasoning can be removed at a sufficiently high temperature (~500 °C), as found in oven self-cleaning cycles.
Aluminium and its alloys have low strength at high temperatures, distort when being welded, and the copper-containing ones are poorly weldable. Aluminium wire rings can be used as cheap gaskets in demountable seals. Aluminium has high thermal conductivity, good corrosion resistance, and low solubility of hydrogen.
It is one of the most commonly used aluminium alloys for highly stressed structural applications and has been extensively used in aircraft structural parts. [ 2 ] 7075 aluminium alloy's composition roughly includes 5.6–6.1% zinc , 2.1–2.5% magnesium , 1.2–1.6% copper , and less than a half percent of silicon, iron, manganese, titanium ...
Note that the term aircraft aluminium or aerospace aluminium usually refers to 7075. [65] [66] 4047 aluminium is a unique alloy used in both the aerospace and automotive applications as a cladding alloy or filler material. As filler, aluminium alloy 4047 strips can be combined to intricate applications to bond two metals. [67]
Anodized aluminium has had the naturally occurring layer of aluminium oxide thickened by an electrolytic process to create a surface that is hard and non-reactive. It is used for sauté pans, stockpots, roasters, and Dutch ovens. [10] Uncoated and un-anodized aluminium can react with acidic foods to change the taste of the food.
