Aluminium Powders for Fireworks, Civil Explosives & Defence Applications
Pyrotechnic Aluminium Powder is a specialized high-reactivity metal powder designed for controlled energy release applications. These grades are engineered to deliver precise burning rates, optimized gas expansion, and consistent performance in fireworks, mining explosives (slurries), and defense-related formulations.
The product range includes pyrotechnic aluminium powders, fireworks-grade powders, and flake aluminium systems designed for both high-intensity effects and controlled energetic performance.
