What is vacuum arc remelted (VAR) ?
- For applications requiring a high-quality material with low contents of impurities, thus extremely low contents of non-metallic inclusions, metal melted in the normal way can be remelted in a high-vacuum (HV) furnace. This production method is called VAR (vacuum arc remelting) and 'HV' is added to the material grade designation. Titanium and zirconium and their alloys, are used in a large number of high-integrity applications, where cleanliness, homogeneity and improved fatigue properties in the final product are essential.
