Product Description

Aluminum powder is a silver-white, highly active fine metal powder with the chemical formula Al. It typically has a particle size of 1–50 μm. Featuring light weight, high reflectivity, electrical/thermal conductivity, and strong reducibility, it is widely used in coatings, metallurgy, military, new energy, and other fields.

Product properties & Features

  • Lightweight & High Strength: Density is 1/3 that of iron, with high specific strength, ideal for lightweight applications.

  • High Reflectivity/Shielding: High reflectivity to light, heat, and electromagnetic waves, used in thermal insulation coatings and electromagnetic shielding.

  • Electrical & Thermal Conductivity: Excellent electrical/thermal conductivity for heat dissipation and conductive materials.

  • High Activity/Reducibility: Strong reducibility with intense exothermic reactions, suitable for propellants and pyrotechnics.

Applications

  • Metallic Pigments

  • Thermal Interface Material

  • Solar Cell Conductive Paste

  • Powder Metallurgy

  • Chemical catalysis industry

  • Thermal Spray

  • Refractory Material

  • 3D Printing

  • Sputtering Targets

  • HTPB/AP/Al propellant

Packing & Storage

25kg/barrel, 27 barrels in one pallet.

40kg/barrel, 18 barrels in one pallet.

Dust Explosion Prevention: Workshops require ventilation, anti-static measures, and explosion-proof electrical equipment; control dust concentration strictly.

Storage & Transportation: Keep dry, sealed, away from ignition sources/oxidizers, and moisture-proof.

Export Control: Highly active/superfine aluminum powder (especially military-grade) is a dual-use item subject to export control, requiring compliance approval.
