XICRU™ SiC Silicon Carbide Aluminum & Zinc Crucibles

High-Performance Isostatic pressed  reinforced SiC-graphite matrix Crucibles for Aluminum & Zinc Alloy Smelting

Our Series NF Crucibles can tolerate severe temperatures without compromising structural uprightness for aluminum, aluminum alloys, and zinc alloy smelting. Over long operating cycles, these crucibles resist low-temperature oxidation and maintain strength. The iron-free composition prevents metal contamination in aluminum melts, which is fundamental for high-purity casting. These crucibles work well in coke-fired and gas-fired furnaces with a melting range of 620-920°C for many industrial applications. Thermal conductivity is improved by the silicon carbide-infused matrix, lowering heat-up times and energy utilization. Thermal stress cracking, frequent in crucibles with fast heating and cooling cycles, decreases by this arrangement. Lower thermal expansion coefficients avoid microfractures while raising service life and lowering costs. Slag adherence is minimized by the low-wettability surface chemistry, which renders cleaning more straightforward and limits downtime between smelting cycles. NF Series (Black): These crucibles undergo an initial application of an anti-oxidation coating, followed by an additional firing process to enhance durability and thermal stability.
