MHC Alloy in Vacuum Furnace

MHC Alloy Picture
MHC Alloy Picture Inquiry & Feedback

MHC alloy (Molybdenum Hafnium Carbon Alloy) is high-performance molybdenum-based high-temperature alloy strengthened by in-situ dispersed HfC particles. Manufactured from high-purity molybdenum through powder metallurgy, the alloy features uniformly distributed HfC strengthening phases that significantly improve high-temperature strength, creep resistance, and microstructural stability. These properties make MHC alloy an ideal material for vacuum furnace components operating under prolonged high temperatures, high vacuum, and repeated thermal cycling.

1. Advantages of CTIA's MHC Alloy in Vacuum Furnace
(1) Excellent High-Temperature Strength: Maintains high mechanical strength above 1000°C for continuous furnace operation.
(2) Outstanding Creep Resistance: Dispersed HfC particles suppress dislocation movement and grain boundary migration, minimizing creep deformation during long-term service.
(3) Superior Microstructural Stability: The recrystallization temperature above 1500°C minimizes grain growth and maintains dimensional stability.
(4) Excellent Vacuum Compatibility: The melting point of approximately 2620°C and low vapor pressure minimize evaporation under high-vacuum conditions.
(5) Excellent Thermophysical Properties: Thermal conductivity of approximately 120–150 W/(m·K) and low coefficient of thermal expansion improve temperature uniformity while reducing thermal stress.

2. Applications of CTIA's MHC Alloy in Vacuum Furnace
(1) Vacuum Hot Zone Systems: Heating element supports, heat shields, support frames, and connecting components.
(2) Vacuum Sintering Furnaces: Load frames, trays, support components, and hot zone structural components.
(3) Vacuum Heat Treatment Furnaces: Material racks, fixtures, load-bearing components, and support structures.
(4) Vacuum Brazing Furnaces: High-temperature fixtures, positioning tools, and connecting components.
(5) High-Temperature Hot Zone Components: Support rings, support rods, connecting parts, and other heat-resistant structural components.
