3105 Aluminum Coil
3105 aluminum alloy coils offer excellent strength, formability, corrosion resistance, and weldability, and play an important role in industries such as construction, transportation, electronics, home appliances, and advertising. Their multiple temper options make them suitable for applications with varying strength and processing requirements, especially for outdoor environments and high-strength sheet metal fabrication tasks.
3105 aluminum alloy is based on 98% pure aluminum and typically contains small additions of alloying elements such as copper, magnesium, manganese, and silicon to enhance its strength. This alloy belongs to the non-heat-treatable, work-hardened aluminum alloy category.
3105 is a non-heat-treatable 3000 series wrought aluminum-manganese alloy, with higher strength than 1100 and 3003 alloys. 3105 aluminum coils are available in various tempers (O, H12, H14, H16, H18, H24, H26, H28) and thicknesses, with surface treatments suitable for construction, waterproof panels, and general sheet metal applications.
- Series and UNS: Belongs to the 3000 series (manganese) wrought alloys; UNS A93015.
- Name meaning: "3" indicates Mn series, "1" denotes a variant of 3005, "05" specifies the particular alloy.

Comparison of 3105 Aluminum with Other Alloys
- Compared to 3003: Due to the addition of magnesium and titanium, it has higher strength and better fatigue resistance.
- Compared to 5052: Lower corrosion resistance, but more cost-effective for non-marine applications.
- Compared to 6061: Better formability, but lower strength; 6061 is heat-treatable.
Comparison Between 3105 and 3003 Aluminum Alloys
Although the two are very similar, 3105 is generally considered a "stronger version" of 3003:
- Strength: Due to its higher magnesium content, 3105 has approximately 10-20% higher strength than 3003.
- Formability: 3003 is easier to deep draw, while 3105 is more suitable for rolled forming and applications like exterior wall panels that require "stiffness."
- Surface treatment: 3105 is more commonly used in color-coated (painted) applications.
Workability and Limitations of 3105 Aluminum Coil
- Formability: Excellent performance in annealed (O) condition, suitable for bending and stamping.
- Weldability: Compatible with TIG, MIG, and resistance welding.
- Machinability: Due to the soft texture in annealed condition, lubricants are required during machining.
- Limitations: Not heat-treatable; strength can only be improved through cold working.
