Description

Aluminium (Fine Powder) 325 Mesh is a high-purity, finely divided metallic aluminum powder with a controlled particle size distribution. This material is critical for applications requiring high reactivity, excellent thermal and electrical conductivity, and a high surface-area-to-volume ratio. It is an essential raw material for industries such as pyrotechnics, metallurgy, and advanced material manufacturing, where consistent quality and reliable supply are paramount.

Application

• Pyrotechnics and Explosives: A key fuel component in flash powders, thermite mixtures, and solid rocket propellants due to its high reactivity and energy release.
• Metallurgy and Alloying: Used as a master alloy additive in steel production and aluminum foundries to control grain structure and enhance mechanical properties.
• Chemical Synthesis: Acts as a powerful reducing agent in organic chemistry and for the production of other aluminum compounds.
• Refractory and Ceramic Materials: Incorporated into castables and composites to improve thermal shock resistance and generate in-situ reinforcing phases.
• Conductive Paints and Inks: Provides metallic sheen and electrical conductivity in specialized coatings and printed electronics.
• Additive Manufacturing (3D Printing): Used in selective laser melting (SLM) processes to produce complex, high-strength aluminum components.
• Aerospace and Automotive: Employed in lightweight composite materials and specialized welding applications.

Quality Control

Our Aluminium Powder 325 Mesh is manufactured under strict quality control protocols to ensure batch-to-batch consistency and performance. We adhere to relevant industry standards for metallic powders. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing key parameters such as purity, particle size distribution, and active aluminum content. Customized quality specifications to meet specific customer and application requirements are available.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Due to its pyrophoric nature and tendency to be easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep container tightly sealed when not in use to minimize contact with moisture and air. Store separately from strong oxidizers, acids, and halogens.
