Zinc and zinc alloy powder for additive manufacturing

1 Scope

GB/T 47094-2026 is the Chinese national standard covering zinc powder for printing - a metal chosen for biodegradable implants, since a zinc scaffold dissolves in the body at a useful rate, and one whose low boiling point makes it awkward under a laser. It fixes the composition, the particle size distribution and morphology, the flowability and the packing density. First edition. It was issued on 28 January 2026 and has been in force since 1 August 2026, as a first edition. The document is under the responsibility of the China Nonferrous Metals Industry Association. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.
