MHC Alloy Picture Inquiry & Feedback

MHC alloy (Molybdenum Hafnium Carbon Alloy) is molybdenum-based dispersion-strengthened high-temperature structural material designed for high-temperature vacuum and controlled-atmosphere sintering environments. Under continuous operation at 1200°C–1700°C with repeated thermal cycling, shrinkage of green bodies, and high-temperature loading, these conditions place strict demands on sintering setter plates, including high load-bearing capacity, creep resistance, anti-warping performance, and excellent dimensional stability. Conventional molybdenum or tungsten setter plates are prone to deformation and thermal fatigue cracking during long-term service, while MHC alloy significantly improves structural reliability through HfC dispersion strengthening.

1. Why Choose MHC Alloy for Sintering Setter Plates?
CTIA's MHC alloy provides the following advantages for ceramic sintering setter plate applications:
(1) Excellent High-Temperature Strength: Maintains strong mechanical performance at 1200°C–1700°C for continuous high-temperature loading.
(2) Outstanding Creep Resistance: HfC dispersion phases effectively suppress grain boundary sliding, reducing long-term deformation and sagging.
(3) High Dimensional Stability: The recrystallization temperature above 1500°C ensures long-term flatness under repeated thermal cycling, reducing ceramic warping risk.
(4) Excellent Thermal Fatigue Resistance: Low thermal expansion minimizes thermal stress during heating and cooling cycles, improving thermal shock resistance and service life.
(5) Good Thermal Conductivity: Promotes uniform heat distribution inside the furnace, ensuring high consistency and uniformity of ceramic sintering.

2. Applications of CTIA's MHC Alloy in Ceramic Sintering Setter Plates
(1) Oxide Ceramic Sintering: Setter plates for structural and functional ceramics, improving load stability and heating uniformity.
(2) Nitride Ceramic Sintering: Used in sintering processes for silicon nitride and aluminum nitride, enhancing high-temperature load capacity and deformation resistance.
(3) Electronic Ceramic Sintering: Used in multilayer ceramic devices and functional electronic ceramics to improve dimensional accuracy and consistency.
