Discontinued (Discontinued) AL6624 Aluminum Magnesium Erbium Zirconium Alloy Powder (AlMgErZr)

Aluminium-Magnesium-Erbium-Zirconium-Alloy Powder (AlMgErZr) Description

Aluminium-Magnesium-Erbium-Zirconium-Alloy Powder (AlMgErZr) is a high-performance alloy powder based on aluminium, developed for applications that require a balanced combination of strength, corrosion resistance, and thermal stability. The powder features a spherical morphology typically achieved through gas atomisation, ensuring excellent flowability, packing density, and uniform layer deposition in additive manufacturing and powder metallurgy processes.

This alloy exhibits a fine and stable microstructure that does not show grain coarsening under thermal stress. The addition of magnesium improves solid-solution strengthening and corrosion resistance, while erbium and zirconium work to refine the grain structure and stabilise the intermetallic phases. These elements contribute to maintaining strength and ductility at elevated temperatures and provide low thermal expansion.

AlMgErZr powder also features low porosity and good weldability, making it suitable for the fabrication of highly integrated components. Its combination of lightweight properties, high strength-to-weight ratio, and excellent environmental resistance makes it an ideal choice for advanced construction and manufacturing environments.

Related Information

1. Raw Materials - Aluminium (Al)

Aluminium with atomic number 13 and symbol Al is a lightweight, silver-white metal known for its low density (2.70 g/cm³) and excellent corrosion resistance. It has a melting point of 660.3 °C and exhibits high ductility, allowing it to be easily formed into sheets, wires, or powders. Aluminium has exceptional thermal and electrical conductivity, only surpassed by Copper among common metals. As the most abundant metal in the Earth's crust, it is widely used in aerospace, construction, packaging, and electronics. Its recyclability (only 5% of the energy required for primary production) further contributes to sustainability. In alloys such as AlMgSc, aluminium serves as the base matrix, providing structural integrity while retaining lightweight properties.

Raw Materials - Magnesium (Mg)

Magnesium with atomic number 12 (symbol Mg) is the lightest structural metal with a density of 1.74 g/cm³ and a melting point of 650 °C. It is highly reactive, especially in powdered form, where it can ignite easily when exposed to air. Nevertheless, magnesium offers an excellent strength-to-weight ratio and is biocompatible, valuable for biomedical implants. It is extracted from seawater or minerals such as dolomite and is an important alloying element in aluminium-based materials. In AlMgSc alloys, magnesium enhances strength and reduces overall weight, although its flammability necessitates careful handling during powder processing.

Raw Materials - Erbium (Er)

Erbium in aluminium alloys contributes to grain refinement and improved thermal stability. When added in small amounts, erbium forms fine, stable intermetallic compounds that prevent grain growth during temperature fluctuations or prolonged exposure to high temperatures. This results in a more stable microstructure and improved mechanical properties, such as increased strength and creep resistance at elevated temperatures. In addition, it helps to reduce microsegregation and enhance the uniformity of the alloy, which is particularly beneficial for additive manufacturing and highly integrated structural components.

Raw Materials - Zirconium (Zr)

Zirconium is a high-melting transition metal with atomic number 40, atomic weight 91.22 g/mol, a density of 6.52 g/cm³, and a melting point of 1 855 °C. It frequently occurs in nature in conjunction with Hafnium and must be processed through complex methods for purification. Notable properties of zirconium include excellent corrosion resistance (particularly in high-temperature steam or acidic media) and outstanding neutron absorption, making it a key component of structural materials for nuclear reactors (e.g., zirconium alloy cladding tubes). In aluminium alloys, trace amounts of zirconium (0.1-0.4%) help refine grains, prevent recrystallisation, and enhance high-temperature strength (up to 300 °C) as well as fatigue resistance through the formation of nanoscale Al₃Zr precipitates. Furthermore, zirconium reduces the coefficient of thermal expansion of the alloy and improves dimensional stability, making it suitable for precision components. Despite its high cost, its enhancement of material properties, particularly in additive manufacturing in aerospace, makes it a critical additive in the development of high-end alloys.
