Quality Control
Quality and process control are the key drivers of our sucess.

Each of our products is initially produced in Induction melting furnaces, where the melt chemistry is trimmed to bring the melt into strict accordance with the product specification.

This is then followed by a specific degassing phase to ensure optimum metal quality.

The products then enter the next phase of production where they are dried, processed and classified before final packaging.

During this phase the differant materiasl are tested multiple times for screen analysis, morphology, durability, hardness, microstructure and specialized testing like specific and relative densities, Corrosion, Magnetic Susceptibility, work hardening etc.
