Buying Guide

Know the aluminum alloy

6063 aluminum is common for extrusions and offers good corrosion resistance and machinability for structural and cosmetic applications

Match OD and wall thickness

Choose the correct outer diameter and wall gauge (for example 1/4" OD with 0.04" wall or 3/8" OD with 0.04" wall) to ensure required strength and fit for fittings or welds

Pick the right profile

Round tubes are useful for shafts and rails, square and rectangular tubing provide flat surfaces for mounting and greater bending resistance for light structural use

Consider finish and length

Mill-finish extrusions are economical, while specified lengths (12"–36") affect cut needs and overall project cost; verify length matches your workflow to minimize cutting

Use ratings and pack quantities

Customer ratings (e.g., 4.4–4.9 stars) and pack sizes (single pieces vs. multi-packs like 4–6 pcs) indicate consistent quality and better value-per-length for repetitive builds
