Spherical Aluminium Powder Description
Spherical Aluminium Powder is a light, silvery-white to gray, odorless powder. It is a reactive flammable material. Aluminum powder is used for several applications such as the manufacture of slurry, explosives, and detonators, the thermit process used for the manufacture of ferroalloys, and for specialized welding applications such as rails, pyrotechnic to manufacture crackers, sparkles, and other pyrotechnic products. And it is also used in the production of different types of electronics. In addition to those uses, it is found in a lot of different paints and sealants on the market as well. Aluminum powder can be used to identify fingerprints and can also be used as fireworks.
Spherical Aluminium Powder for 3d Printing
Metal powders used for 3D printing generally require high purity, good sphericity, small particle size distribution, and low oxygen content. Currently, the main metal powders used for 3D printing include titanium alloys, cobalt-chromium alloys, stainless steel, iron powder, aluminum powder, and aluminum alloys.
Advantages of Aluminium Use in 3D Printing
- Low Melting Point: Aluminum has a low melting point, and therefore its laser sintering temperature in 3D printing is lower compared to other metal materials.
- Low Density: Aluminium can be used in the fabrication of lightweight structures and is even referred to as the "metal that can fly." As it is, support during printing is less compared to other metal materials.
- Improveable Strength: Pure aluminum has low strength, yet through alloying with other elements, the strength of aluminum can be significantly enhanced.
- Good Plasticity and Easy to Process: Aluminum can be drawn into tubes and thin wires and into various profiles through extrusion. There are even research reports on using aluminum materials in FDM (Fused Deposition Modeling) printing.
Disadvantages of Using Aluminium in 3D Printing
- High Chemical Reactivity: When aluminum is in powder form, the surface area of aluminum becomes greater, which once more elevates its chemical reactivity. This makes it prone to burning, reducing processing safety.
- Low Strength and Poor Mechanical Properties: Aluminium possesses low strength and poor mechanical properties compared to certain other metallic substances.
- Difficulty in Sintering: It is simple for a dense and strong aluminum oxide film to develop on the surface of aluminum, making the sintering of aluminum difficult.
* The above disadvantages can be to some extent overcome by aluminum alloy powders.
Spherical Aluminum Powder Properties
Spherical aluminum powder is characterized by uniform particle size and a narrow distribution range, high tapped density, excellent sphericity, low impurity content, and an active aluminum content exceeding 99%. It has a silvery-gray appearance, is free from foreign inclusions and agglomerates, and has an extremely low moisture content, making it suitable for long-term storage.

FAQs about Aluminium
1. Is aluminium powder safe?
Aluminium powder can be hazardous as it is highly flammable and may cause explosions when dispersed in air. Proper handling, storage, and safety measures are essential to minimize risks.
2. What is the difference between aluminium and aluminum?
"Aluminium" is the British English spelling, while "aluminum" is the American English spelling for the same chemical element with the symbol Al.
3. What element destroys aluminium?
Chlorine is a key element that can destroy aluminum by reacting with it, leading to corrosion and degradation of the metal.
4. What does aluminium not react well with?
Aluminum does not react well with oxygen in dry conditions due to its protective oxide layer, making it resistant to corrosion. It is also generally unreactive with noble gases and stable under inert atmospheres.
