4. Classification of Titanium Zirconium Molybdenum Alloy Bar Dia.20mm:
TZM molybdenum alloy rod can be divided into the following types according to the degree of processing:
Sintered TZM alloy rod: The sintered TZM rod is a rod without subsequent processing, and the surface is gray-black without metallic luster.
Forged TZM alloy rod: After forging, the TZM rod will have a layer of oxide on the surface, and the surface will show a black metal-free color.
Polished TZM alloy rod: The TZM rod can be polished one or more times according to the surface state and quality requirements, and the surface of the polished TZM rod is silver-gray metallic luster.
Polishing TZM alloy rods: Polishing TZM rods refers to polishing the rods to reduce the surface roughness of the alloy rods, thereby obtaining bright and flat TZM rods.
Alkali-washed TZM alloy rods: Alkali-washed TZM rods are obtained through the alkali-washing process. The surface of the alkali-washed TZM rods has a gray metallic luster and is relatively smooth.
