(Glare1 can only consist of aluminum layers of 0.3 to 0.4 mm (0.012 to 0.016 in; 12 to 16 mils) thickness, though.) For example, Glare4B-4/3-0.4 is a Glare sheet with a Glare4 grade (using the B variant) where there are four aluminum layers and three glass fiber layers, and the thickness of each aluminum layer is 0.4 mm (0.016 in; 16 mils).

Accuracy: Panels and blocks made of autoclaved aerated concrete are produced to the exact sizes needed before leaving the factory. There is less need for on-site trimming. Since the blocks and panels fit so well together, there is less use of finishing materials such as mortar.
The elastic modulus of concrete can vary widely and depends on the concrete mix, age, and quality, as well as on the type and duration of loading applied to it. It is usually taken as approximately 25 GPa for long-term loads once it has attained its full strength (usually considered to be at 28 days after casting).
Typical applications include marine, aircraft, architecture, general sheet metal work, heat exchangers, fuel lines and tanks, flooring panels, streetlights, appliances, rivets and wire. The exceptional corrosion resistance of 5052 alloy against seawater and salt spray makes it a primary candidate for the failure-sensitive large marine ...
