Aluminium Powder market segmentation is driven primarily by application and material type. In terms of application, additive manufacturing accounts for roughly 30% of revenue, reflecting the rapid adoption of powder‑bed fusion processes that demand high‑purity, spherical particles. The automotive sector contributes about 25%, where the powder is used for lightweight structural components and friction materials. Aerospace follows with a 20% share, leveraging the powder for high‑strength, heat‑resistant alloys in engine and airframe parts. Electronics represent 15% of the market, primarily for conductive inks and thermal‑management coatings. The remaining 10% is allocated to specialty coatings and other niche uses. Regarding types, the market is split between atomized and gas‑atomized powders, each offering distinct particle‑size distributions that affect flowability and sintering behavior. The alloy‑free category dominates volume, but alloyed powders—such as Al‑Si, Al‑Cu—capture premium pricing due to enhanced mechanical properties. This dual‑layer taxonomy clarifies how each segment underpins the overall market size, illustrating the breadth of Aluminium and Aluminium Alloy Powder segmentation.
