NFA offers a wide range of products in angular or blocky shapes (CA or CU types) and different purity levels (CA standard or CAHPF high purity grades) for best results in blasting operations. These product lines are available in macro and micrograins for covering for all sandblasting purposes. They are fully compliant with most of the existing blasting machines and systems.
The Chemicals and Petrochemicals industries are in need for good quality substrate materials to refine liquids and gases. In conjunction with the active catalytic substance, WFA grains and Bubble Alumina will provide mechanical strength as the catalyst carrier, as well as chemical inertness, for best efficiency in our customers’ units and reactors.
For critical parts made through investment casting processes, our premium quality and our large range of products will answer tough requirements for dimensional accuracy and thermal stability, especially for the aerospace, automotive and medical (i.e. knees or hips prosthesis) sectors for instance.
With suitable sizing, white fused alumina can be used in all kinds of foundries or steel plants as a metal filter and for slowing down the speed of the metal stream. Thanks to its high temperature resistance and stable composition, white fused alumina is the finest and long-lasting solution for metal filtration.
Thanks to one of its intrinsic properties, White Fused Alumina (WFA) is naturally refractory. Standard WFA grades are commonly used here, in the refractory sector, for either refractory bricks, monolithic and castable, refractory concretes or clays.
Bubble Alumina can be used to bring porosity and lighten final refractory products. It is used in fluidized bed kilns as well.
Nitrides based products are usually used for tap hole clays.
