Which is sturdy, aluminum lean pipe or stainless steel pipe?

Aluminum lean tube, also known as aluminum wire rod, is a type of aluminum alloy tube with a cross dovetail groove. In terms of the hardness of lean tubes, there are two types: aluminum and stainless steel. Stainless steel is a pure round tube with different wall thicknesses, but aluminum alloy tubes come in multiple specifications, and their strength and bending resistance are also higher than those of stainless steel tubes.

The tooling fixtures made by combining aluminum lean tubes and lean tube connectors, such as lean tube workbenches, are definitely more sturdy compared to stainless steel tubes. For this cross dovetail groove shape, the mating surfaces and screw fixation of the matching connectors are very firm, while stainless steel has a smooth surface and slightly lower load-bearing capacity than aluminum alloy tubes.
