5052 is an aluminium–magnesium alloy, primarily alloyed with magnesium and chromium. 5052 is not a heat treatable aluminum alloy, but can be hardened through cold working. [ 2 ] Chemical properties
The K-factor is the bending capacity of sheet metal, and by extension the forumulae used to calculate this. [1] [2] [3] Mathematically it is an engineering aspect of geometry. [4] Such is its intricacy in precision sheet metal bending [5] (with press brakes in particular) that its proper application in engineering has been termed an art. [4] [5]
An aluminium alloy (UK/IUPAC) or aluminum alloy (NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper , magnesium , manganese , silicon , tin , nickel and zinc .
The foil can be used as a pyrotechnic heat source, a replacement of potassium chlorate/iron pellets, for thermal batteries. It reacts faster than the conventional composition, reaches higher temperatures, and heat buffers of inert metal (e.g. steel) are needed to lower the peak temperature and prolong the heat delivery.

Microscopic close-up of aluminium foil on the back of an intumescent rubber strip. Aluminium foil has a thickness less than 0.2 mm (7.9 mils); thinner gauges down to 6 μm (0.24 mils) are also commonly used. [8] Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy-duty household foil is typically 0.024 mm (0.94 mils).
Aluminium is the most common metal used for deposition, but other metals such as nickel and chromium are also used. The metal is heated and evaporated under vacuum. This condenses on the cold polymer film, which is unwound near the metal vapour source. This coating is much thinner than a metal foil could be made, in the range of 0.5 micrometres ...
As of 1995, Henkel's Alodine 1200s commercial formula for aluminum consisted of 50-60% chromic anhydride CrO 3, 20-30% potassium tetrafluoroborate KBF 4, 10-15% potassium ferricyanide K 3 Fe(CN) 6, 5-10% potassium hexafluorozirconate K 2 ZrF 6, and 5-10% sodium fluoride NaF by weight. The formula was meant to be dissolved in water at the ...
The four most common aluminium grades available as sheet metal are 1100-H14, 3003-H14, 5052-H32, and 6061-T6. [5] [7] Grade 1100-H14 is commercially pure aluminium, highly chemical and weather resistant. It is ductile enough for deep drawing and weldable, but has low strength.
