Aluminum 8006 vs 8176

Aluminum · grade comparison

Aluminum 8006 and 8176 are both aluminum grades. 8006 is the stronger of the two: yield strength 130 MPa (18.9 ksi) against 85 MPa (12.3 ksi) for 8176, about 53% more; tensile strength follows at 155 MPa (22.5 ksi) vs 110 MPa (16 ksi). In exchange, 8176 is the more ductile: elongation 20% versus 10% for 8006, and 8006 is harder (45 HB vs 30 HB). 8006 runs hotter in service (120°C vs 90°C continuous) and 8176 conducts heat better (230 W/m·K vs 185 W/m·K). On the shop floor, 8176 welds better (excellent vs very good) and 8006 sits in a lower cost tier (budget, $) than 8176 (standard, $$).

8006Choose it when strength drives the design, or when the part sees heat.

8176Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
