Insist on AFCO 6061-T6 threaded aluminum drawn tubing for strength, durability, and precise fit.  Extruded tubing looks similar, but it is not as strong or durable. Extruded parts are prone to failure, while drawn parts keep performing. Drawn material offers the same strength as hex without the additional weight!
