3004 aluminum disc

What is the 3004 Aluminum Disc circle?

The 3004 aluminum alloy is part of the 3000 series, primarily composed of aluminum (Al) and manganese (Mn), with a small percentage of magnesium (Mg). Its chemical composition grants it enhanced strength and corrosion resistance compared to other aluminum alloys, such as 1100 or 3003.

Key Chemical Composition of 3004 Alloy:

• Aluminum (Al): 96.8%–98.2%
• Manganese (Mn): 1.0%–1.5%
• Magnesium (Mg): 0.8%–1.3%
• Other Elements (e.g., Iron, Silicon): ≤ 0.7%

This alloy is non-heat-treatable but achieves its strength through work-hardening. It is widely recognized for its excellent formability, moderate strength, and superior corrosion resistance in environments exposed to moisture or chemicals.

Key Properties of 3004 Aluminum Discs

3004 aluminum discs inherit the alloy’s characteristics, making them ideal for demanding applications. The following properties define their performance:

1. Corrosion Resistance

The manganese in the alloy enhances its natural oxide layer, providing superior resistance to rust and pitting, even in humid or marine environments. This property is critical for cookware, roofing systems, and chemical storage applications.

2. Moderate Strength

While not as strong as the 5000 or 6000 series alloys, 3004 aluminum offers a good balance of strength and flexibility. Its strength is higher than the 1100 or 3003 series, making it suitable for lightweight yet durable products.

3. Excellent Formability

3004 aluminum discs can undergo processes like deep drawing, spinning, and stamping without cracking. This makes them particularly valuable in manufacturing cookware, such as pots and pans, and decorative components.

4. Lightweight

With a density of approximately 2.73 g/cm³, 3004 aluminum discs are lightweight, reducing the overall weight of finished products while maintaining structural integrity.

5. Thermal and Electrical Conductivity

Although its conductivity is lower than that of pure aluminum (e.g., 1100 alloy), it is sufficient for many applications, including heat distribution in cookware.

Applications of 3004 Aluminum Discs

Due to their unique properties, 3004 aluminum discs find applications in a wide range of industries:
