Features of 3D Printing Aluminum Based Alloy AlSi7Mg Powder

It provides a good strength-to-weight ratio. After 3D printing, parts made from this powder can endure moderate mechanical loads. The alloy’s structure gives it decent ductility, so it can withstand some deformation without fracturing, which is crucial for parts in dynamic applications.

Thermal Attributes

AlSi7Mg powder has relatively high thermal conductivity. This makes it ideal for applications where heat dissipation is needed, like electronic devices cooling down components. Its low melting point, around 570 – 630 ° C, streamlines the 3D printing process as it can be quickly melted and strengthened layer by layer.

Processing Advantages

The powder has excellent flowability, ensuring smooth and even distribution during powder-bed-based 3D printing techniques. This leads to high-quality prints with accurate dimensions and a good surface finish. It also makes the creation of complex shapes, providing design flexibility for manufacturers.

Corrosion Resistance

A natural oxide layer forms on the surface of printed parts, offering some level of corrosion resistance in everyday environments and protecting the integrity of the components over time.

 Production Method of 3D Printing Aluminum Based Alloy AlSi7Mg Powder

Gas Atomization Method

Raw Material Melting: High-purity aluminum, silicon, magnesium and other raw materials are proportionally charged into a high-temperature melting furnace and melted at 700 – 800°C in an inert gas atmosphere to form a homogeneous molten metal liquid.

Atomization and Powder Formation: The molten metal liquid is sprayed downward through a nozzle by high-pressure argon or nitrogen gas. The high-pressure gas shears the molten metal into tiny droplets, which quickly solidify in the air to form AlSi7Mg alloy powder.

Plasma Rotating Electrode Process

Electrode Preparation: An alloy rod of appropriate composition is made into an electrode.

Melting and Centrifugal Atomization: The electrode rotates at high speed in a plasma torch. The plasma arc melts the end of the electrode, and the centrifugal force generated by the high-speed rotation throws the molten metal out in the form of droplets.

Solidification into Powder: The droplets solidify rapidly in an inert gas environment to form spherical AlSi7Mg powder.

Mechanical Alloying Method

Raw Material Mixing: Aluminum, silicon, magnesium and other raw materials in powder form are accurately weighed and mixed in a ball mill.

Mechanical Alloying: Through the impact and friction of grinding balls in the ball mill, the raw material powders are continuously deformed, welded and broken, gradually forming AlSi7Mg alloy powder with a uniform composition.
