Why Not Any Aluminum? Engineered Powders’ Necessity
The soil in any pile will not hold its shape if one tried to create a sandcastle of it. In the same way, standard aluminum is inadequate for the complicated and precise procedures of additive manufacturing. It doesn’t matter if you are directing a stream of energy and material (Directed Energy Deposition) or melting the powder using the help of a laser (Powder Bed Fusion) The AM techniques require fast cycles of cooling and heating. In the event that aluminum particles aren’t well developed, these extreme conditions could cause major problems.

Key Aluminum Alloys Used in Additive Manufacturing
Aluminum additive alloys has an array of different alloys, each suited to specific needs and requirements for performance. For simplicity we can categorize commonly used Aluminum additive-based manufacturing alloys by their main alloying elements as well as common applications:
Common Additive Manufacturing Aluminum Alloys:
| Property Category | Key Alloying Elements (Main) | Typical Composition (Approximate Range, wt%) | Common Examples | Main Characteristics | Typical Applications |
| High Strength | Aluminum (Al), Magnesium (Mg), Scandium (Sc), Copper (Cu) | Al-5-12Mg, Al-0.1-0.6Sc, Al-3-5Cu | Scalmalloy®, AlCu4MnSi | High tensile and yield strength, good fatigue resistance (Scalmalloy®), high hardness (AlCu4MnSi) | Aerospace structural components, high-performance automotive, tooling, motorsport |
| Good Weldability & General Purpose | Aluminum (Al), Silicon (Si), Magnesium (Mg) | Al-9-11Si, Al-0.2-0.4Mg; Al-6-8Si, Al-0.2-0.6Mg | AlSi10Mg, AlSi7Mg | Good printability, moderate strength and ductility, good corrosion resistance (Al-Si-Mg) | General engineering parts, automotive components, heat sinks, brackets, housings |
| High Ductility & Corrosion Resistance | Aluminum (Al), Magnesium (Mg) | Al-4-6Mg | AlMg5 | High elongation, good corrosion resistance, moderate strength | Marine applications, food processing equipment, components requiring good formability |
Note: The “Typical Composition” provides a general range for the main alloying elements. Other minor elements may also be present to influence specific properties.
Properties and Performance of AM Aluminum Alloys
The unique process conditions of aluminum additive manufacturing may produce microstructures and other properties that are different from traditional components. But, with the correct alloy and printing parameters that are optimized high performance can be obtained.
Here are the properties of two typical types:
| Property | Typical Values for AM AlSi10Mg (Heat Treated) | Typical Values for AM Scalmalloy® (Heat Treated) | Notes |
| Tensile Strength | 400-450 MPa | > 500 MPa | Indicates the maximum stress the material can withstand before breaking. |
| Yield Strength | 300-350 MPa | > 450 MPa | Indicates the stress at which the material begins to deform permanently. |
| Elongation at Break | 5-10% | 10-15% | Measures the ductility or how much the material can stretch before breaking. |
| Hardness (HV) | 120-130 | 140-160 | Resistance to indentation. |
The tailored properties of these aluminum additive manufacturing alloys are what make them so valuable for creating functional and high-performance parts through 3D printing.
