3105 Aluminum Sheet Supplier | ASTM B209 AA3105 Sheet, Plate & Coil Manufacturer
As a professional 3105 aluminum sheet supplier, we deliver a high-strength, corrosion-resistant alloy that outperforms pure aluminum (1100/3003) by approximately 20% in strength, while retaining excellent formability for bending, roll forming, and deep drawing. 3105 aluminum sheet is a 3000-series aluminum-manganese alloy with a nominal composition of 98% aluminum plus manganese and magnesium additions. It meets ASTM B209 and is available in tempers O through H28, thicknesses 0.15mm – 6.0mm, and widths up to 2650mm. Surface options include mill finish, painted (PE/PVDF), and coated. Third-party inspections (SGS, BV) are welcome. Full mill test certificates and material traceability are provided with every shipment.
3105 aluminum sheet is a non-heat-treatable alloy; strength is achieved through cold working (strain hardening) to various H tempers. Its superior corrosion resistance ensures long-term durability in humid and outdoor environments, forming a self-repairing protective oxide film when scratched. The alloy also offers excellent weldability using gas, arc, and resistance welding methods. Common applications include residential siding, mobile homes, roofing panels, rain gutters, signage, and color-coated architectural coil. 3105 is a preferred substrate for PE/PVDF painted aluminum coil in construction and building applications.

FAQ
Q1: What is the MOQ for 3105 aluminum sheet?
MOQ is typically 1–5 tons depending on size and temper. We may offer smaller quantities for stock sizes.
Q2: What is the lead time?
Stock items: 5–7 days. Custom orders: 10–25 days depending on quantity and specification.
Q3: What is the difference between 3105 and 3003?
3105 has higher hardness (46 BHN vs. 42 BHN for H14) and fatigue strength. 3003 contains more magnesium; 3105 contains small amounts of titanium, chromium, and copper for enhanced strength.
Q4: Is 3105 suitable for painting and coating?
Yes. 3105 is an excellent substrate for PE- and PVDF-coated coil, commonly used in roofing and siding.
Q5: Can 3105 be welded?
Yes. 3105 has excellent weldability using gas, arc, and resistance welding methods.
Q6: What are common tempers for 3105?
Common tempers include O, H12, H14, H16, H18, H22, H24, H26, H28, and H112.
Q7: What is the price of 3105 aluminum sheet?
Price depends on temper, thickness, quantity, surface finish, and market conditions. Contact us with specifications for a firm quote.
Q8: What is 3105-H14 used for?
