6-Series Aluminum Alloys & Selection Guide
Common 6-series aluminum sheets include 6061, 6063, 6082, 6101, 6060. 6061 is the most widely used, with high strength, good weldability, and corrosion resistance, suitable for structural parts, profiles, machinery, and automotive components. 6063 features excellent extrudability and surface finish, mainly used for architectural profiles, doors, windows, and decorative parts. 6082 has higher strength than 6061, applied to heavy-duty structural parts. 6101 & 6060 are for high-surface-quality profiles.
Choose by demand: Select 6061 for general structural strength; 6063 for extrusion and appearance; 6082 for heavy load; and others for special surface or conductivity requirements.
Frequently Asked Questions
What are the main temper options available for 5052 aluminium sheet?
5052 aluminium sheet is available in several temper conditions including O (fully annealed), H32 (strain hardened and stabilized), H34 (strain hardened and stabilized to a higher degree), and H112 (as-fabricated with some work hardening), among others. Each temper offers different balances of strength and formability to suit specific application requirements.
What thickness and width range does 5052 aluminium sheet come in?
5052 aluminium sheet is available in thicknesses ranging from 0.3 mm to 600 mm and widths from 50 mm to 1200 mm. Both DC (Direct Chill) and CC (Continuous Casting) production types are offered to accommodate diverse industrial needs.
Why is 5052 aluminium commonly used in marine applications?
5052 aluminium contains magnesium (approximately 2.386%) and chromium, which provide excellent corrosion resistance, particularly in saltwater and marine environments. Its combination of moderate-to-high strength, good weldability, and resistance to seawater corrosion makes it ideal for boat hulls, deck plates, and marine hardware.
How does 5052 aluminium differ from 6061 aluminium?
5052 is a 5-series (Al-Mg) alloy known for superior corrosion resistance and formability, making it ideal for marine, architectural, and sheet metal applications. 6061 is a 6-series (Al-Mg-Si) alloy offering higher overall strength, better machinability, and heat-treatability, making it preferred for structural components, machinery, and automotive parts.
What is the difference between DC and CC type aluminium sheets?
DC (Direct Chill) casting produces ingots with a more uniform microstructure and is typically used for higher-quality, thicker plates requiring superior mechanical properties. CC (Continuous Casting) is a more cost-efficient process used for thinner sheets and coils, offering faster production rates suitable for general-purpose applications.
Which 6-series aluminium alloy should I choose for architectural profiles?
For architectural profiles such as doors, windows, curtain walls, and decorative trim, 6063 is the most recommended alloy. It offers excellent extrudability, a smooth surface finish ideal for anodizing or powder coating, and sufficient strength for architectural applications. If higher structural strength is needed, 6061 or 6082 would be more appropriate choices.
