MHC Alloy Products

MHC alloy (Molybdenum Hafnium Carbon Alloy) is molybdenum-based high-temperature alloy that uses high-purity molybdenum as the matrix and forms in-situ HfC dispersion-strengthening phases through the reaction of Hf and C. Based on nearly 30 years of molybdenum and molybdenum alloy manufacturing experience, CTIA GROUP has optimized composition, microstructure, and processing technology to achieve excellent high-temperature performance. CTIA’s MHC alloy products include plates, sheets, rods, discs, tubes, rings, electrodes, and custom components.

Features of CTIA’s MHC Alloy Products
(1) Stable Composition System
Mo 98.5%–99.0%, Hf 1.0%–1.2%, C 0.05%–0.15%; low impurity content ensures high purity and material stability.
(2) HfC Dispersion Strengthened Structure
HfC particles are formed in situ during vacuum sintering and uniformly distributed in the Mo matrix, creating a stable strengthening structure.
(3) Excellent High-Temperature Performance
Tensile strength is approximately 800 MPa at room temperature and approximately 500 MPa at 1000°C. Recrystallization temperature exceeds 1500°C. And the recommended service temperature is ≤1550℃.
(4) Good Thermophysical Properties
High melting point of approximately 2620°C, high thermal conductivity, low thermal expansion coefficient, and excellent thermal shock resistance.
(5) Machining and Service Performance
Suitable for turning, drilling, and grinding, with excellent creep resistance and dimensional stability at high temperatures.

Applications of CTIA’s MHC Alloy Products
MHC alloy provides excellent high-temperature strength, creep resistance, and structural stability for extreme thermal load and high-reliability applications. It is widely used in the following fields:
(1) High-Temperature Thermal Processing and Vacuum Furnace Systems
Used for hot-zone components, heating components, support plates, and structural parts in vacuum furnaces above 1500°C.
(2) Hot Processing Dies and High-Temperature Forming Tools
Used for hot forming dies, extrusion dies, forging dies, and stamping die components under high temperature, high stress, and thermal cycling conditions.
(3) Aerospace and Nuclear High-Temperature Components
Used for aerospace hot-end structures, engine-related high-temperature parts, and nuclear industry structural components, maintaining reliability under extreme thermal loads and complex stress environments.
(4) X-Ray Rotating Target Systems
Used for X-ray rotating anode targets and high-speed rotating structural components under high heat flux and thermal fatigue conditions.
(5) Electron Beam Evaporation and Vacuum Deposition Equipment
Used for electron beam evaporation components, sputtering target components, and vacuum coating system parts.
(6) Semiconductor and Precision Vacuum Systems
Used for semiconductor thermal processing components, vacuum hot-zone structures, and precision support parts requiring high dimensional stability and low contamination.
