Aluminum-based 3D Printing Powder

Introduction to aluminum-based 3D printing powder

Aluminum-based 3D printing powder is a metal powder material used for additive manufacturing (such as SLM, SLS and other processes), the main components of which are aluminum and its alloys (such as AlSi10Mg, Al6061, etc.). It has lightweight, high strength and good thermal conductivity, and is widely used in aerospace, automotive and electronics fields.

Characteristics of aluminum-based 3D printing powder

Lightweight: low density, suitable for weight reduction design.

High strength: some alloys have excellent mechanical properties after heat treatment.

Corrosion resistance: an oxide film can be formed on the surface, which is resistant to environmental corrosion.

Thermal conductivity and electrical conductivity: suitable for heat dissipation components or electronic devices.

Easy processing: good fluidity, suitable for high-precision printing.
