TZM material is an alloy of 0.50% Titanium, 0.08% Zirconium and 0.02% Carbon with the balance Molybdenum and is typically manufactured by powder metallurgy or arc-casting processes. It has a higher recrystallization temperature, higher creep strength & hardness, and higher tensile strength than pure molybdenum. In addition, TZM exhibits good thermal conductivity, low vapor pressure, good corrosion resistance and is machinable.
TZM Molybdenum Physical Properties:
Density: 10.22g/cc, 0.37lb/in3
Melting Point: 2623°C, 4753°F
Thermal Conductivity: 0.48 Cal/cm2/cm°C/sec
Specific Heat: 0.073 Cal/gm/°C
Coefficient of Linear Thermal Expansion: 2.50 micro-in/°F x 10-6
Electrical Resistivity: 6.85 micro-ohm-cm
The molybdenum TZM is a normally utilized constructional material for high-temperature applications. These microstructural aspects significantly affect quality at raised temperatures. By methods for carbide-reinforcing TZM features improved high-temperature quality up to 1400 °C and a higher recrystallization temperature, contrasted with pure Molybdenum.
A few types of molybdenum alloys are accessible. TZM alloy bar was chosen as the most appropriate material based on its unrivaled high-temperature elasticity and a high recrystallization temperature (somewhere in the range of 1400 and 1600 C). A high recrystallization temperature is especially significant as this dispenses with the probability of recrystallization during brazing welding causing a misfortune in malleability and quality.
Our TZM Alloy is of the highest quality and conforms to ASTM B386 type 364 (TZM Plate) and B387 type 364 (TZM Rod) standards, which is made by powder metallurgy. Process of TZM products: Raw powder mixture-Pressing-Sintering-Forging-Rolling to plate & sheet-Swaging & drawing to rod & wire. TZM tubes are mostly drilled from rods, length is quite limited. Other processes as turning, cutting, grinding, drilling, are also engaged for machined TZM parts
Available in rod, plate, tube, sheet, wire, fasteners and customized form, it is often used for hardware in vacuum furnaces, large x-ray equipment, and in creating tools. TZM Alloy is used in high-temperature applications involving demanding mechanical loads, for example in forging tools or as rotating anodes in X-ray tubes. The recommended temperatures of use are between 700 and 1,400 °C.
