What Is 3104 Aluminum Alloy?<\/h2>\n

3104 aluminum alloy (UNS A93104, EN AW-3104 \/ EN AW-Al Mn1Mg1Cu) is a non-heat-treatable 3000 series aluminum alloy primarily alloyed with manganese (Mn) and magnesium (Mg). It was developed as an evolution of 3004 with tighter compositional control for high-volume can body manufacturing, and has since become the dominant alloy for aluminum beverage can body stock worldwide.<\/p>\n

The alloy’s defining property is its excellent deep drawing and ironing behavior. In the annealed (O) temper, 3104 sheet or coil can be deep drawn into a cup, then ironed through progressive rings to reduce wall thickness \u2014 forming the seamless thin-walled can body that defines modern aluminum beverage packaging. The final H19 temper achieved through this cold working delivers the strength needed for can integrity at minimal wall thickness.<\/p>\n

3104 also finds use in other forming-intensive applications outside of can making, including chemical equipment, building products, and general sheet metal work. It is supplied under ASTM B209, EN 485\/573, and GB\/T 3880, and is available through Linsy in sheet, coil, bar, and tube product forms.<\/p>\n

Propiedades mec\u00e1nicas seg\u00fan el estado de templado<\/h2>\n

The mechanical properties of 3104 aluminum vary significantly with temper. The alloy is typically used in work-hardened tempers for strength-critical applications, while annealed (O) temper is preferred for forming-intensive processing. The values below are typical ranges for sheet product per ASTM B209 and EN 485-2.<\/p>\n\n\n\n\n\n\n\n\n\n

Gu\u00eda para la selecci\u00f3n del temple<\/h2>\n

Selecting the right temper for your 3104 aluminum project depends on the balance between formability and strength your process requires.<\/p>\n

O Temper \u2014 For Deep Drawing and Complex Forming<\/h3>\n

3104-O is the fully annealed condition with the lowest strength and highest formability. Choose O temper when the material needs to be deep drawn, ironed, or formed into complex shapes in the as-received condition. This is the starting condition for can body production, where the blank is drawn and ironed in multiple stages to form the can wall.<\/p>\n

H12 \/ H14 \u2014 For Moderate Strength with Retained Formability<\/h3>\n

3104-H12 and H14 provide intermediate strength levels for applications that require a degree of structural stiffness but still need some forming capability. These tempers are suitable for general sheet metal parts, chemical equipment components, and building products.<\/p>\n

H16 \/ H19 \u2014 For Higher Strength Parts<\/h3>\n

3104-H16 and H19 deliver the highest strength available in this alloy series. While H19 is primarily achieved through the can-making process itself (drawing + ironing) rather than supplied as raw material, H16 is available as supply temper for applications needing elevated strength. These tempers have limited post-supply formability and are best suited for applications where the supplied temper is close to the final required condition.<\/p>\n

Key Characteristics of 3104 Aluminum<\/h2>\n

Excellent Deep Drawing and Ironing Performance<\/h3>\n

The defining characteristic of 3104 is its suitability for deep drawing followed by ironing \u2014 the two-step process that forms aluminum can bodies. In the O temper, 3104 sheet can be drawn into a cup and then progressively ironed to reduce wall thickness down to approximately 0.1 mm while increasing can height, all without tearing or fracturing. This combination of deep drawability and ironability is achieved through carefully controlled grain structure (fine, equiaxed grains) and the strengthening contribution of Mn and Mg dispersoids that resist strain localization.<\/p>\n

Strong Work Hardening Response<\/h3>\n

3104 work-hardens significantly during cold deformation. Starting from ~120 MPa in O temper, the alloy can reach over 275 MPa through cold working (H19). This means parts formed from 3104-O gain substantial in-service strength purely from the forming process, often eliminating the need for post-forming heat treatment. The work hardening curve is well-suited to the strain distribution in drawn-and-ironed cylinders, providing higher strength in the thin-walled regions where it is most needed.<\/p>\n

Good Weldability and Corrosion Resistance<\/h3>\n

3104 can be welded using common aluminum welding methods including TIG (GTAW) and MIG (GMAW), as well as resistance welding. The alloy has moderate general atmospheric corrosion resistance, similar to other 3000 series alloys. For applications in aggressive chemical environments or where maximum corrosion resistance is required, 5000 series alloys or post-weld surface treatments may be more appropriate. 3104 does not require post-weld heat treatment to restore corrosion resistance, unlike heat-treatable alloys.<\/p>\n

Notas sobre el procesamiento y el acabado superficial<\/h2>\n

Forming and Drawing<\/h3>\n

3104-O is the preferred starting temper for deep drawing and ironing. For less demanding forming operations, H12 and H14 tempers may be formed directly. Lubrication is critical for ironing operations \u2014 specialized can-body drawing lubricants are standard practice in high-volume can manufacturing. For general press forming, standard aluminum forming lubricants are suitable.<\/p>\n

Welding<\/h3>\n

TIG (GTAW) and MIG (GMAW) welding are suitable for 3104. Recommended filler alloys include 4043 (Al-Si) for general applications and 5356 (Al-Mg) where higher weld strength is required. Note that welding will soften the heat-affected zone, reducing strength in work-hardened tempers. For structural welds in H14 and higher tempers, design with the understanding that the as-welded HAZ strength will be closer to O temper properties.<\/p>\n

Acabado de superficies<\/h3>\n

3104 accepts standard aluminum surface treatments including anodizing, chemical conversion coating, painting, and powder coating. Anodizing on 3104 produces a grayish to clear finish suitable for protective and decorative applications. For mirror or bright anodized finishes, 5000 or 6000 series alloys are typically preferred. Mechanical finishing options include polishing, brushing, and mill finish.<\/p>\n

Corte<\/h3>\n

3104 sheet and coil can be cut by shearing, slitting, laser cutting, or water jet cutting. For thick sections (bar and tube), band saw and circular saw cutting are standard methods. Linsy offers cut-to-length and cut-to-size services on request.<\/p>\n
