Buying Guide

Choose the right alloy and temper

6063 aluminum is common for tubing with good corrosion resistance and extrusion quality; verify temper or finish if surface hardness or machining behavior matters

Match profile to application

Round, square and rectangular profiles offer different torsional and bending characteristics—round for shafts and rails, square/rectangular for framing and light structural use

Check OD and wall thickness

Outer diameter and wall thickness (for example 0.04" walls on 1/4" and 3/8" round examples) determine stiffness and load capacity more than length alone

Confirm length and pack quantity

Lengths here range up to 36" and items are sold in multi-piece packs or single lengths; plan cuts and joints to minimize waste and splices

Consider finish and machining needs

Mill-finish extruded tubing (as listed for square and rectangular sections) is economical but may need deburring or anodizing for cosmetic or wear requirements
