Pyrotek® Granulated Foundry Flux

With proven aluminium expertise from the smelter to the foundry, Pyrotek offers a comprehensive range of melt treatment, degassing and flux-injection solutions for aluminium foundries, including five blends of granulated fluxes for cleaning and drossing applications. In addition, Pyrotek manufactures rotary and stationary flux-injection equipment to maximize effectiveness of flux to reduce dross and increase metal quality.

Benefits:• Improves metal quality, reduces scrap and melt loss

• Extends crucible and furnace life

• Reduced dust and fine emissions

• Optimized and consistent grain size

• Alloy specific formulations available (see reverse side)
