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.
Fine grades of our high-purity WFA are the material of choice to make ceramic coatings in oxygen sensors (also known as lambda sensors). Most stringent emission standards are met by the automotive industry thanks to these sensors measuring the oxygen content in the combustion products before they reach the catalytic converter. This measurement by the sensor will drive the engine (ignition and injection) to get to the optimum fuel mixture.
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.
