Propellant-grade aluminium powder is a finely divided metallic fuel used in qualified solid-propellant and energetic-material programmes. Spherical atomized grades support controlled flow, packing and programme-specific performance, with acceptance requirements established by the selected standard, grade and contract: available exclusively through controlled, authorised supply channels.

Controlled material profile
DLA ASSIST identifies MIL-PRF-23950 as the active performance specification for four types of spherical aluminium powder used as propellant ingredients. MIL-DTL-512 covers flaked, grained and atomized aluminium powder for energetic applications. Final acceptance limits depend on the selected type, grade, current revision and contract.
01
Purity and active metal
Chemical purity and active metallic aluminium are controlled to limit impurity variability and establish the available metallic content.
02
Particle distribution
Programme-defined particle-size distribution supports consistent material behaviour and controlled acceptance between qualified production lots.
03
Spherical morphology
Atomized spherical grades provide controlled flowability, packing behaviour and formulation rheology for qualified industrial programmes.
04
Traceable supply
Every enquiry is subject to end-use review, grade definition, specification alignment, lot documentation, packaging and regulatory approval.
Programme-specific supply
Artillerie Inrichtingen Armaments BV can support authorised customers with grade selection, qualified sourcing, supplier coordination, certificate-of-analysis review, approved industrial packaging and specialised logistics.
The final purity, active aluminium content, particle distribution, morphology, apparent density, moisture limit, quantity, packaging and delivery conditions are established through the contracted technical and regulatory framework.

Combustible-dust safety and regulatory control
Micronised aluminium powder can form explosible dust clouds. Supply, storage, handling and use require the current safety data sheet, a site-specific occupational risk assessment, appropriate dust-explosion controls, approved equipment and procedures, qualified personnel, and compliance with applicable chemical, workplace, dangerous-goods, defence and export-control requirements. Any explosives-precursor obligations must be assessed for the specific material, intended use and transaction. Classification and transport status remain product-, particle-size- and packaging-specific.
