Titanium-zirconium-molybdenum rods (TZM rods) are prepared by powder metallurgy. TZM rod is a high-temperature alloy prepared by adding trace elements such as Ti, Zr and C to the base of molybdenum. It has good high temperature performance, mechanical properties and other good properties, including: high melting point, high strength, high elastic modulus, low linear expansion coefficient, low vapor pressure, good electrical and thermal conductivity, strong corrosion resistance and good high temperature mechanical properties, etc. , Which can be widely used in many fields.
classification
TZM alloy rods can be divided into the following types according to the degree of processing:
Sintered TZM rod: The sintered TZM rod is a bar that has not undergone subsequent processing, and its surface is gray-black and has no metallic luster.
Forged TZM rod: After forging, the surface of the TZM rod will have a layer of oxide, and the surface will show a black metal-free color.
Polished TZM rod: TZM rod can be polished one or more times according to the surface condition and quality requirements. The surface of the polished TZM rod is silver-gray metallic.
Polished TZM rod: Polished TZM rod refers to polishing the rod to reduce the surface roughness of the alloy rod, thereby obtaining a bright and flat TZM rod.
Alkali-washed TZM rods: Alkaline-washed TZM rods are processed through alkali-washing process. The surface of alkali-washed TZM rods presents a gray metallic luster and is relatively smooth.
Application
TZM rod has good high temperature performance and mechanical properties, so it is widely used in various high temperature fields. It is often used to manufacture electric vacuum devices and electric light source parts, and is suitable for processing ion implantation parts. As a high-temperature heating element and high-temperature structural parts, it is often used as an electrode in a furnace in the glass and refractory fiber industry. It works in a glass melt at 1300°C. It has good performance and long service life. It is also often used as an electrode in the rare earth industry and is widely used. In addition, TZM rods can also be used in hot runner systems to prepare various types of hot nozzles and hot runners.
