7075 vs 6061 aluminum extrusions for strength and structure I often decide between 7075 and 6061. Both are common extruded alloys but serve different needs. 7075 is much stronger, but 6061 is easier to work with. I\u2019ll explain the key differences simply. Let\u2019s compare strength, machinability, cost, and structural performance side by side. How do 7075 and 6061 strengths compare? I once used 7075 for a high?stress aerospace part. It lasts under heavy load. 7075 is much stronger than 6061 in tensile and yield strength.
