Aheadd® CP1

Ideal for heat transfer applications in the motorsport, defense & aerospace industries.

Material & Process Capability

Aheadd is Constellium’s new generation of optimized high-performance aluminium powders for Laser Powder Bed Fusion (LPBF). This Aluminum-Iron- Zirconium powder solution designed specifically for additive manufacturing using laser powder bed fusion (L-PBF). Aheadd CP1 brings multiple advantages including high strength & ductility, excellent thermal & electrical conductivity, high productivity LPBF processing, and simplified postprocessing. It is ideal for heat transfer applications in the motor sports, defense, & aerospace industries.

General Process

This data sheet specifies the expected mechanical properties and characteristics of this alloy when manufactured on a Velo3D Sapphire System. Parts built from Aheadd CP1 on a Sapphire System can be heat treated using a simplified process compared to other Aluminum alloys making it an attractive choice for consistent material properties. All data is based on parts built with Velo3D standard 50 μm layer thickness parameters. Velo3D uses Constellium Aheadd CP1.
