Aluminum Square Tubing Strength Chart
The fatigue strength of aluminum and its alloys varies from about one quarter to one half of the tensile strength for sections having smooth surfaces and no abrupt changes of contour.
Aluminum square tubing strength chart. 1 what is the minimum size of square tube i can use to support the load of the catamaran given the attached diagram. The modulus of elasticity of aluminum and aluminum alloys is approximately 10 300 000 lbs sq. Square tube assumes bending with one side parallel to the load think square vs diamond.
The calculated section property values do not comply with the aisi or aisc specifications since minimum material thickness and rounded corners were not used. Don t forget that putting hard metal close to occupants is very dangerous so the use of proper seating restraints padding and helmets should always be considered. The safety factors use the numbers in the table below for strength.
Both 6061 and 6063 aluminum are majorly composed of magnesium and silicon but 6061 aluminum possesses a tensile strength of at least 290 mpa or 42 000 psi where 6063 has a tensile strength of at least 140 mpa or 20 000 psi. The section properties for square and rectangular tube are calculated exclusive of the corner radii. Square fit steel tubing.

The section property and load values provided herein are based on nominal material thickness and square corners. The moduli of elasticity used are 29 700 000 psi for steel and 10 000 000 psi for aluminum. Modulus of elasticity fatigue strength.
The steel weights are tweaked for mechanical tubing and will be less accurate for structural tubing.
