3104 Aluminum Plate

3104 aluminum plate is a versatile Al-Mg-Mn alloyrenowned for its balanced strength, corrosion resistance, and formability. Here's a comprehensive overview:

Composition

• Primary Elements:

• Manganese (Mn):0.8–1.4% (improves strength and corrosion resistance).

• Magnesium (Mg):0.8–1.2% (enhances ductility and weldability).

• Iron (Fe) ≤0.8%, Copper (Cu) 0.05–0.25%, Silicon (Si) ≤0.5%(trace elements for process control).

• Aluminum (Al):Balance.

• Structure: A solid-solution matrix with Mn-rich precipitates, contributing to its non-heat-treatable strengthening mechanism

Mechanical Properties

• Tensile Strength:

• H19 Temper: 270–320 MPa (ideal for high-strength applications like 易拉罐罐体).

• O Temper (Annealed): ~150 MPa (maximizes ductility for deep drawing).

• Yield Strength:

• H19: 240–280 MPa.

• O: ~50 MPa.

• Elongation:

• H19: 3–5%.

• O: 20–25% (excellent for complex forming) .

• Hardness: ~80–100 HB (H19), ~30 HB (O).

• Formability: Exceptional deep-drawing capabilities, with a Lankford coefficient (r-value) of 1.2–1.5, enabling thin-wall reduction in packaging .
