TZM moly rod/bar molybdenum and zirconium-titanium alloy rods
TZM alloy rod, molybdenum and zirconium-titanium alloy rods, titanium zirconium molybdenum alloy bar:
TZM alloy is a molybdenum-based alloys commonly used in a high-temperature alloys containing 0.50% titanium, 0.08% zirconium, the remaining 0.02% carbon molybdenum alloy.
TZM alloy rod advantages:
1) TZM alloy has good mechanical properties, in particular its mechanical properties are better than that of pure molybdenum at high temperatures. Table 2 (Ti0.5 / Zr0.1) TZM alloy mechanical properties, Table 3 TZM (Ti0.5-Zr0.08) the tensile strength and elongation at high temperatures.
2) TZM alloy (molybdenum zirconium-titanium alloy) also has good weldability, the material can be well H11 steel welding. Meanwhile TZM alloy is resistant to liquid metals such as Zn corrosion. It is cold-worked by conventional methods. In the case of cooling lubricants available cemented carbide or high speed steel cutting tools for machining.
