3000 Series Aluminum Properties and Applications
Aluminum alloys are now the leading material choice for many sectors thanks to their malleability, low weight, and great corrosion resistance. The 3000 series aluminum alloys are the stars of this show with their specific properties, and are easy to adapt. In addition to their main elements – aluminum and manganese, the alloys have shown their way to be applied to many other application areas, from packaging to construction, and to form a unique appearance. Here we provide the potential, future, and demand for aluminum in the world, in addition to focusing on the properties, applications, processing techniques, and market outlook of the 3000 series aluminum.
Chemical Composition and Physical Properties
The 3000 series aluminum alloys have a name based on their chemical composition, which has a large effect on their mechanical and physical properties.
Chemical Composition of 3000 Series Aluminum Alloys
Aluminum is the primary and initial component in 3000 series aluminum, which is more than 96% of its material. Manganese is the primary ingredient for the alloy, mostly ranging between 1% and 1.5%. Other than manganese, a small proportion of other materials, such as copper, iron, and/or silicon, can also be used for its production for better standardized properties. The percent value for manganese, along with other materials, can be different for specific materials in the 3000 series, such as 3003, 3004, or 3105.
Physical Properties of 3000 Series Aluminum
Density: Approx. 2.73 g/cm³, which is way less by mass than steel (7.85 g/cm³) and suitable for relatively lightweight applications.
Melting Point: In the region of 650°C.
Thermal Conductivity: Relatively high – about 50-60% of copper, given the balance between heat transfer efficiency and cost-effectiveness, rendering it suitable for heat transfer applications.
Electrical Conductivity: Moderate, a little less than pure aluminum. A conductivity of 50–55% IACS means it is an excellent heat-conducting component.
Corrosion Resistance: Excellent. Essentially equivalent to pure aluminum, so it possesses excellent resistance to exposure to the atmosphere, fresh water, and organic acids (e.g., food-grade environment). However, surface treatment (like anodizing) is a must to get relief in prolonged exposure to acidic solutions of pH less than 4.0.
Workability: This composition provides good weldability (TIG/MIG) and tolerance to cold-working, like bending and rolling. This allows the manufacturing of complex parts, processes used typically in electrical goods.
- Physical Properties: Variable based on an alloy and temper.
- Tensile strength: 150–185 MPa, depending on the H14 temper condition.
- Elongation: 8–16% (based on temper state), providing maximum formability for subsequent stamping and deep-drawing processes.
The Brinell hardness number (HB) for unhardened metal lies between 30 and 40.
