Furnace Components 

Many high temperature industrial furnaces use molybdenum (moly) components for such things as elements, element supports, power terminators, and process fixtures. Hot Isostatic Press (HIP) construction requires shells fabricated from molybdenum sheets. These are used to support the heating elements, and may also act as shielding. Likewise, flat heating elements made from moly sheet are used in vacuum and hydrogen furnaces. Heat shielding and other furnace components and structures help round out the use of moly in the furnace industry.

Molybdenum-Tungsten

Molybdenum-Tungsten(Tungsten-Molybdenum)

Molybdenum (Mo) and tungsten (W) are two elements in the same column of the periodic table. They also behave similarly in nature. The average concentration in the Earth's crust is 1.5 ppm for both elements. Molybdenum is an essential nutrient for plants and animals. At large concentrations, Mo may be toxic. This is sometimes the case for leachates from alkaline ashes. Tungsten is an important strategic metal that is used in a variety of industrial applications. It is usually mined from scheelite, CaWO4, och wolframite, (Fe,Mn) WO4. Tungsten is released to the environment, e.g. through its use in winter tires and ammunition. On the whole, the environmental behaviour of tungsten is not well known. 
 

Molybdenum Disilicide Heating Element

Molybdenum Disilicide Heating Element

Molybdenum disilicide heating element is a kind of resistance heating element basically made of high pure molybdenum disilicide. In oxidizing atmosphere, on the surface of molybdenum disilicide heating element owing to the high temperature combustion a layer of compact quartz protective film is formed to prevent molybdenum disilicide from continuously oxidizing. In oxidizing atmosphere , its max temperature can reach 1800 °C and its applicable temperature is 500-1700 °C. It can be widely used in such applications as sintering and heat treatment on ceramics, magnet, glass, metallurgy, refractory, etc. We can offer different types of products—ED type, W type, U type and L type to customers according to their needs. 
 

TZC (Molybdenum alloy)

TZC (Molybdenum alloy)

Four main classes of commercial molybdenum alloy exist. The most common of the carbide-strengthened alloys is known as TZM. Other alloys in this class include TZC (1.2% titanium, 0.3% zirconium, 0.1% carbon), MHC (1.2% hafnium, 0.05% carbon), and ZHM (1.2% hafnium, 0.4% zirconium, 0.12% carbon). 
 

TZM

TZM

TZM (Titanium-Zirconium-Molybdenum) alloy (High Temperature Alloy) is a solid-solution hardened and particle-strengthened molybdenum based alloy. The development of a Mo-Ti solid solution and the fine dispersed Ti-carbides are responsible for the excellent strength properties at temperatures up to 1400°C. The recrystallization temperature of TZM (Titanium-Zirconium-Molybdenum) alloy is approximately 250°C higher than moly and it offers better weldability.
