Currently, the most common mold materials are copper-silver (CuAg) and copper-chromium-zirconium (CuCrZr) alloys. Both alloys share the characteristic of exhibiting greater hardness and/or strength—as well as a significantly higher recrystallization temperature—compared to unalloyed copper. This allows for an extended service life for our molds. In terms of thermal conductivity, CuAg performs on par with unalloyed copper, while CuCrZr maintains a value of approximately 80% of that maximum. Utilizing modern CNC machinery, we ensure the highest possible precision for molds with tight tolerances. To further enhance service life, the working surfaces of the molds—those in contact with the molten raw material—are typically plated to specific thicknesses; we guarantee a high standard of quality for the hard chrome or thick nickel plating applied. Furthermore, these coatings help prevent surface defects, such as cracks, that could otherwise arise from direct contact between the copper mold and the cast strand.
