What is 3005 Aluminum Alloy?
3005 aluminum alloy is a member of the 3000 series aluminum-manganese (Al-Mn) family, a non-heat-treatable, corrosion-resistant aluminum alloy. With manganese (Mn) as its primary alloying element (1.0-1.5%) and the addition of 0.2-0.6% magnesium (Mg), its strength is approximately 20% higher than that of 3003 aluminum alloy, while retaining excellent corrosion resistance and formability.
Worthwill specializes in manufacturing 3005 aluminum in various forms, including 3005 aluminum sheet, 3005 aluminum coil, and 3005 aluminum strip. These products are widely used in architectural decoration, transportation, electronics, packaging containers, and other fields.

Frequently Asked Questions (FAQ)
Q1: What is the difference between 3005 and 3003 aluminum alloy?
A: 3005 has a higher manganese content (1.0-1.5%) and includes added magnesium (0.2-0.6%). This makes it about 20% stronger than 3003 and provides superior corrosion resistance, especially in humid and marine environments.
Q2: What is the difference between 3005 aluminum sheet, coil, and strip?
A: While they share the same chemical composition and properties, their main difference lies in form and application. Sheet is ideal for structural and decorative panels, coil is suited for continuous processing, and strip is used for precision stamping and deep-drawn parts.
Q3: Which temper should I choose?
A: For deep drawing, O or H14 tempers are recommended. For general architectural and appliance applications, H14 or H24 offer the best balance of strength and formability. For high-strength requirements, choose H16 or H18. Worthwill offers free selection advice based on your specific process.
Q4: What is the difference between H14 and H24 tempers?
A: Both have similar strength levels. However, H24 is strain-hardened and then partially annealed, resulting in lower internal stress and better formability for secondary processing. H14 has a slightly higher surface hardness and is better suited for direct stamping.
Q5: What is the minimum order quantity (MOQ) and lead time?
A: The MOQ for standard specifications is 1 ton, and for custom specifications, it is 3 tons. In-stock products ship within 3-7 business days, while custom orders take 15-25 business days. Expedited delivery can be arranged for urgent orders.
Q6: How do you guarantee product quality?
A: Worthwill implements quality control from raw material inspection and in-process monitoring to final product testing. We provide a full set of documentation, including chemical composition, mechanical property, and dimensional inspection reports, along with a Mill Certificate. We also support third-party inspection and on-site customer witnessing.
