Product Details

Product Description

As core components in high-temperature heat treatment equipment, our molybdenum alloy heating elements are manufactured using high-purity molybdenum base materials and special doping processes, designed specifically for extreme high-temperature environments. These elements can be used up to near melting point temperatures in hydrogen or dissociated ammonia atmospheres, and operate stably up to 2000°C in nitrogen environments. Our precision CNC machining technology ensures dimensional accuracy and surface finish of each element, providing excellent creep resistance and dimensional stability at high temperatures.

The core advantage of molybdenum alloy heating elements lies in their high-temperature strength. When operating temperatures exceed 1700°C, we recommend using TZM alloy or molybdenum-lanthanum alloy with higher recrystallization temperatures and better strength. These materials, processed through unique powder metallurgy and doping technologies, significantly increase recrystallization temperature, avoiding premature failure caused by recrystallization embrittlement of conventional molybdenum materials at high temperatures.

Features

Our molybdenum alloy heating elements are optimally designed with the following distinctive features:

Feature Category	Specific Performance
High-Temperature Stability	Continuous operation for 2-3 years in 1700-2000°K range, extremely low vapor pressure in high-temperature vacuum environments
Oxidation Resistance	Dense oxide layer formation on surface, special models with MoSi2 coating for enhanced oxidation resistance
Mechanical Strength	TZM and Mo-La alloys maintain excellent creep resistance at high temperatures, dispersion-strengthened alloys show lower steady-state creep rates at 1800℃
Corrosion Resistance	Resistance to hydrogen and dissociated ammonia corrosion, good ablation resistance in molten quartz environments
Machining Precision	Precision CNC machining ensures dimensional consistency and easy installation
Diversified Design	Available in various forms including wire, rod, strip, and tube, custom geometries supported

Applications

Our molybdenum alloy heating elements are widely used in the following fields:

Aerospace Industry - Heating elements and hot zone structures for high-temperature vacuum furnaces, processing high-performance metals such as titanium, niobium, and tantalum. Hot isostatic pressing (HIP) equipment relies on the high-temperature strength and dimensional stability of molybdenum components.

Glass Manufacturing Industry - As electrodes for electric melting, with only 7.8g loss per ton of glass produced, service life can exceed one year. Also used in glass fiber drawing furnaces, replacing platinum components to reduce production costs.

Electronics and Semiconductor Industry - For sintering ceramic nuclear fuel and oxide ceramics in hydrogen-protected sintering. Mo-50Re and TZM alloys serve as thermionic cathode structural components in high-power microwave tubes, operating at temperatures up to 1200℃.

Ceramic Processing and Powder Metallurgy - As heating elements for high-temperature hydrogen atmosphere furnaces, with long service life and operational reliability. Used as sintering boats and setters for uranium dioxide nuclear fuel sintering.

Scientific Research and Special Material Processing - For ultra-high temperature experimental equipment and special material heat treatment processes, supporting customized designs for specific requirements.
