Opis
Coarse Aluminium Powder (>99.7%)
Other Names: Aluminium granules, Aluminium coarse powder
CAS Number: 7429-90-5
Sum Formula: Al
Molar Mass: 26.98 g/mol
Appearance: Silver-gray metallic granules
Coarse aluminium powder consists of irregular or rounded metallic granules with a high purity level (>99.7%). It is commonly used in metallurgical processes, pyrotechnics, and chemical manufacturing. Due to its reactive nature, especially with oxidizing agents, it is regulated as an explosives precursor under EU Regulation 2019/1148.
