When selecting aluminum for extruded profiles, understanding the 6063 vs 6065 aluminum differences is essential for manufacturers, designers, and engineers. Both are 6000-series heat-treatable alloys with excellent corrosion resistance, but they excel in different areas. As a leading OEM aluminum profiles manufacturer & wholesale supplier, HERO METAL recommends 6063 aluminum for most cabinet handles, window frames, and furniture applications due to its superior extrudability and surface quality.
Key Differences Between 6063 and 6065 Aluminum Alloys
- Chemical Composition: 6063 contains 0.45-0.9% magnesium and 0.2-0.6% silicon for optimal extrusion. 6065 has higher Mg (~1%) and Si, plus bismuth and lead additions for better machinability.
- Mechanical Strength: 6065 delivers higher tensile strength (up to 400 MPa in T6) – ideal for structural parts. 6063 offers moderate strength (186-240 MPa) but superior formability.
- Extrudability & Surface Finish: 6063 is the gold standard for complex shapes and premium anodizing – perfect for visible architectural and furniture profiles. 6065 prioritizes post-extrusion machining over finish.
Applications:
• 6063: Cabinet handles, door/window frames, furniture extrusions, heat sinks – where aesthetics matter.
• 6065: Machined components in aerospace, automotive, high-load structures.
