Refractory Selection Guide Channel Furnace - Copper Click on furnace diagram for product recommendations

We design and manufacture the most complete group of products for furnaces melting, holding, and pouring copper based alloys. V-CAST®, L-CAST®, DRI-VIBE®, MINRO-AL® RAM, MINRO-AL CAST, LCF, and other product lines have been used for many years in uppercase, floor, and throat applications.  L-CAST, LCF, V-CAST®, DRI-VIB®, MINRO-AL RAM, and MINRO-AL CAST, are all industry standards for inductor applications.   We also manufacture DRI-VIBE 432CU, the only USA produced inductor mix formulated primarily with silica.
