0Cr27Al7Mo2 heating resistance wires

Features:

0Cr27Al7Mo2 has unparalleled high-temperature creep resistance (sag resistance). Molybdenum (Mo) is a potent solid-solution strengthening element that significantly improves the high-temperature strength of the ferritic matrix. When horizontally installed at ultra-high temperatures of 1350-1400℃, 0Cr27Al7Mo2 exhibits almost no sagging, whereas standard 0Cr25Al5 would rapidly soften and fracture. Benefiting from the synergistic effect of high chromium (~27%), high aluminum (~7%), and molybdenum, 0Cr27Al7Mo2 can be safely used at a maximum temperature of 1400℃ (short-term up to 1425℃). Even after long-term operation above 1350℃, 0Cr27Al7Mo2 maintains a relatively fine grain structure, preserving good toughness and thermal shock resistance, significantly reducing the risk of sudden fracture due to coarse grains. In extreme environments of 1400℃, its oxidation rate is extremely low, and its service life is typically more than 2 times that of standard 0Cr25Al5. It is particularly suitable for industrial furnaces where life requirements are extremely high and element replacement is difficult (e.g., glass melting tanks, ceramic sintering kilns).It’s room temperature resistivity is approximately 1.53 μΩ·m, one of the highest among common heating alloys. When designing heaters of the same power, shorter wire lengths or larger cross-sectional areas (improving mechanical strength) can be used, facilitating optimized furnace layout and improved structural rigidity of the elements.
