Aluminum B443.0 vs Aluminum 6005 vs Aluminum 6005A vs Aluminum 6011
Side-by-side benchmark of 4 aluminum grades.
PropertiesHow to read this table
- The best value in each row is in bold.
- Values are typical room-temperature figures for the default condition (temper / grade as listed).
- Relative cost is a market tier, not a price — it moves with region and volume.
- Confirm against the certified mill / resin datasheet before design release.
