▎ 摘 要
NOVELTY - Aluminum-based alloy powder comprises aluminum-based powder, multi-layer graphene and aluminum-based powder for alloying to form the tissue. At least part of the surface of the aluminum-based alloy powder is coated by multi-layers of graphene. USE - The aluminum-based alloy powder is useful for 3D printing (claimed). ADVANTAGE - The aluminum-based alloy powder is cheap and eco-friendly, and has high quality and good wettability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the aluminum-based alloy powder.
