ALUMINIUM POWDER & PASTE
Our marketing collaboration with Sri Kaliswari Metal Powder (P)Ltd. gives us the more refined edge in aluminium industry.
Aluminium powder is produced by presenting pure molten aluminium metal to a compressed gas jet and converting it to fine droplets, which are then solidified and collected.
Powders so collected are subsequently graded, depending on size, specification and application. The range of particle sizes of the product made in this way can be controlled to some extent by varying the nozzle opening, the air pressure and other factors.
While, Aluminium paste is made from aluminium foil or aluminium powder, depending on the end use, by ball milling in white spirits solvent with lubricant present.
