Overview: What is Spherical 4047 Aluminum Alloy Powder?

Spherical 4047 Aluminum Alloy Powder is a specialized form of aluminum alloy designed for ease of use i pulvermetallurgi, additiv tillverkning, och brazing. The key differentiator for 4047 alloy, compared to other aluminum alloys, is its high silicon content—typically around 11-13% kisel. This composition makes it ideal for applications requiring good fluidity, lower melting points, och excellent resistance to cracking.

Den spherical shape of the powder particles ensures optimal flowability, which is critical in 3D-utskrifter och laser sintering processes. Additionally, the high silicon content lowers the alloy’s melting point, making it perfect for brazing filler metals och high-precision welding.

But why choose 4047 over other aluminum alloys? The answer lies in its mångsidighet och prestanda, especially when brazing eller additiv tillverkning is involved. Let’s dive deeper.
