Aluminum sheet metal comes in a variety of thicknesses and weights in many different grades. Ryerson offers heat treatable aluminum sheet grades like the popular 6061 aluminum alloy that can be used for commercial applications that require strength corrosion resistance and machinability as well as non heat treatable grades when formability and weldability are priorities. C value of the outdoor air film.

Aluminum alloy 3003 rolled. K factor a constant determined by dividing the thickness of the sheet by the location of the neutral axis which is the part of sheet metal that does not change length. Aluminum duralumin 94 96 al 3 5 cu trace mg 20. Fuel tanks food chemical handling trailer siding roofing etc.

Thermal conductivity for aluminum is 215 w m k from the table above. Aluminum sheets and plates have temper designations indicating that the material has undergone a process to achieve certain properties of strength and hardness. 3003 aluminum sheet has a smooth semi shiny finish and is popular for many applications including. M2 k w u thermal transmittance.

So if the thickness of the sheet was a distance of t 1 mm and the location of the neutral axis was a distance of t 0 5 mm measured from the inside bend then you would. The k factor in sheet metal working is the ratio of the neutral axis to the material thickness. They are nonmagnetic and may come in perforated anodized or painted aluminum sheet and plate form. Perforated aluminum sheet is created by punching a series of holes which are.

Conductive heat transfer per unit area can be calculated as q a 215 w m k 2 10 3 m 80 oc 8600000 w m2. The line where the transition from compression to stretching occurs is called the neutral axis.
