3003 aluminum sheet vs 5052 aluminum sheet:How to choose for architectural decoration

In the field of architectural decoration, 3003 aluminum sheet and 5052 aluminum sheet often cause selection confusion due to performance differences – the former is an aluminum-manganese alloy (Mn content 1.0-1.5%), focusing on lightweight and economy; the latter is an aluminum-magnesium alloy (Mg content 2.2-2.8%), known for high strength and corrosion resistance. The tensile strength of 5052 aluminum sheet is far higher than that of 3003 aluminum sheet, but the unit price is 15-20% higher than the latter. If the usage scenario is mismatched (such as choosing 3003 aluminum sheet in coastal high-humidity areas or 5052 aluminum sheet in inland dry areas), it may cause rust rework or more than 30% budget waste in a few years. The choice of aluminum sheet for architectural decoration needs to be considered comprehensively based on the climate environment, load-bearing requirements and full-cycle costs.

3003 aluminum sheet: the most cost-effective in inland building decoration

✅ ‌Highlights‌

◆ ‌Weatherproof and rustproof‌: With the addition of manganese, the ability to resist UV oxidation is increased by 50% (ASTM B209 standard test)‌

◆ ‌Lightweight and ductile‌: The density is only 2.73g/cm³, and it can be punched into an arc/hollow shape (such as an artistic ceiling)‌

◆ ‌Cost advantage‌: The unit price is 15-20% lower than that of 5052 aluminum sheet, suitable for budget-sensitive projects‌

✅ ‌Recommended scenarios‌

◆ ‌Inland dry environment‌: office curtain wall, shopping mall LOGO, indoor partitions

◆ ‌Short-term decoration projects‌: temporary exhibition venues, commercial display devices

5052 aluminum sheet: the preferred material for coastal building decoration

✅ ‌Performance breakthrough‌

◆ ‌Salt spray test‌: 5000 hours without rust (far exceeding 2000 hours of 3003 aluminum sheet)‌

◆ ‌Strength rolling‌: tensile strength 275MPa , 3003 aluminum sheet is only 145MPa, and its typhoon resistance is doubled ‌

◆ ‌Surface technology‌: Anodizing coloring is more uniform, and it will not fade for 10 years (such as wave pattern etching sheet)‌

✅ ‌Required scene‌

◆ ‌High humidity and high salt area‌: seaside hotel exterior wall, port waiting hall, hot spring resort

◆ ‌Permanent structure‌: special-shaped curved curtain wall, load-bearing decorative column
