TZM Plate or TZM Sheet for Structural Furnace Components 260

Metal sheet/plate is a thin sheet/plate made from different materials of tungsten, tungsten alloys, molybdenum and molybdenum alloys. The sheet could be formed by hot rolling procedures and is polished further with different finishes depending on the applications. TZM has several valuable properties such as high strength, creep resistance, hardness and low vapor pressure in high temperature environments. Sheets/plates made of TZM alloy thus have low expansion coefficient, excellent heat and corrosion resistance and good machinability. Compared with pure molybdenum…

TZM Alloys for Radiation Shielding and Heat Exchangers 279

TZM, also known as titanium zirconium molybdenum, is a mature molybdenum alloy. The main advantage of using it is that it can well support applications where high strength and creep resistance are highly required. It is a stable metal and is not affected by temperature reduction and works well without weakening or softening. Alloying facilitates the vacuum arc casting process by which complete melting and mixing of molybdenum oxide and alloy is accomplished. Therefore, with the help of the two…

Energy Saving SiC Heating Elements and MoSi2 Elements for Electric Furnace 284

There are several types of heating elements available for industrial heating. Generally speaking, metallic heating elements such as nichrome wire (Ni-Cr) are commonly used in lower temperature ranges (up to 1100°C), and MoSi2 elements are often used in high-temperature ranges (1200-1900°C). Silicon carbide (SiC) heating elements cover between the two at temperatures up to 1600°C. Silicon carbide is a ceramic material with relatively high electrical conductivity when compared to other ceramics. The uniqueness of this material is that it has…

How to Choose Sintering Methods for Titanium-Zirconium-Molybdenum (TZM) Alloy? 244

The earliest produced in the industry is titanium-zirconium-molybdenum (TZM) alloy, which is a molybdenum alloy containing 0.4%-0.55% titanium, 0.06%-0.12% zirconium and 0.01%-0.04% carbon. The total amount of alloying element does not exceed 1%. There are two main sintering methods for titanium-zirconium-molybdenum alloy: hydrogen protection sintering and vacuum sintering as following: 1.Hydrogen protection sintering: the product is sintered under the protection of hydrogen. During the process, due to the reduction effect of hydrogen, the oxides in the molybdenum powder will be…

What Are the Benefits of Metal Plating on Molybdenum Copper Alloy 255

Molybdenum is a non-ferrous metal with high melting point, high strength, high hardness, wear resistance, and good thermal and electrical conductivity, while molybdenum copper alloy (Cu-Mo alloy) is a pseudo-alloy made by copper and molybdenum that does not solidify with each other. This alloy contains less copper, so it basically possesses most of the physical and chemical properties of molybdenum, and also has the characteristics of copper at the same time, that is, it has high electrical conductivity, high thermal…

What Do You Know About the Disadvantages of TZM Plate or Sheet? 277

TZM alloy is an attractive molybdenum-based alloy (0.4-0.54% Ti, 0.06-0.12 %Zr, 0.01-0.04% C, balance Mo) utilized in industries with high strength, high temperature and vacuum requirements, including aerospace, electronics and heat treatment. TZM alloy plate can perfectly server these areas when the working temperature ranges from 700 ℃ to 1400 ℃。 Compared with pure molybdenum plate, TZM plate has a more stable crystal structure and a higher recrystallization temperature. This is due to the small amount of zirconium and titanium…
