A205/F1


A205 is a lightweight aluminium powder derived from the aerospace approved (MMPDS) A20XTM alloy, developed and patented by AMT Ltd. With a unique mode of solidification that is an important feature of this patented Al-Cu-TiB2 alloy, A205 is ideal for Additive Manufacturing.

A205/F1 has been formulated to comply with current FIA regulations concerning the use of metal matrix composites (MMC), and is compatible all the leading metal LPBF equipment suppliers. This innovative alloy has already been investigated in several applications within the motorsport sector, and shares much the same properties as the original A205 parent alloy.
