CTIA's TZM Alloy Powder

TZM Alloy Powder (Titanium Zirconium Molybdenum Alloy Powder) is high-performance molybdenum-based alloy powder prepared by adding trace amounts of titanium (Ti), zirconium (Zr), and carbon (C) elements into molybdenum (Mo) matrix. It is an essential raw material for manufacturing TZM alloy plates, blocks, rods, electrodes, rings, crucibles, and high-temperature structural components. With nearly 30 years of experience in molybdenum and molybdenum alloy manufacturing, CTIA uses high-purity molybdenum raw materials and advanced powder metallurgy technologies to achieve uniform composition, low impurity content, and stable sintering performance, meeting the demanding reliability requirements of high-temperature industrial applications.

CTIA's TZM alloy powder is typically produced by precisely proportioning high-purity molybdenum powder, titanium powder, zirconium powder, and carbon sources. Advanced mixing processes, including wet mixing, mechanical alloying, and high-energy ball milling, are applied to ensure uniform dispersion of alloying elements. During subsequent compaction and high-temperature sintering, titanium and zirconium react with carbon to form stable carbide dispersed phases (TiC and ZrC). These nano-scale or micro-scale strengthening phases are uniformly distributed within the molybdenum matrix and along grain boundaries, effectively preventing grain growth and improving high-temperature tensile strength, creep resistance, and microstructural stability.

CTIA's TZM alloy powder features strictly controlled chemical composition with the following typical ranges:
(1) Molybdenum (Mo): ≥99%
(2) Titanium (Ti): 0.40%–0.55%
(3) Zirconium (Zr): 0.06%–0.12%
(4) Carbon (C): 0.01%–0.05%

CTIA can customize powder particle size, oxygen content, carbon content, and impurity element levels according to customer requirements. CTIA's TZM alloy powder has a typical particle size range of 1–10 μm and a loose density of 2.5–4.5 g/cm³, providing excellent flowability, compactability, and sintering activity for manufacturing high-density TZM alloy products. By optimizing particle size distribution, CTIA improves compact densification efficiency, reduces sintering porosity, and enhances the overall performance of final TZM alloy components.

CTIA focuses on raw material purity control, mixing uniformity control, and powder performance evaluation. Through laser particle size analysis, Scanning Electron Microscopy (SEM), Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), and Oxygen-Nitrogen-Hydrogen (ONH) analysis, CTIA strictly controls powder particle size, elemental composition, and gas impurities to ensure stable product quality. High-quality CTIA's TZM alloy powder can produce TZM alloy products with high density, fine grains, and uniform microstructure after sintering. The theoretical density is approximately 10.2 g/cm³, while the actual sintered density can exceed 95% of theoretical density. The recrystallization temperature can reach above approximately 1300°C, enabling the alloy to maintain excellent mechanical properties in high-temperature environments from 1000°C to 1400°C.

CTIA's TZM alloy powder is mainly used in:
(1) TZM alloy product manufacturing: Used as the raw material for producing TZM alloy rods, bars, blocks, and plates, enabling the manufacture of high-strength, high-density, and high-purity molybdenum alloy semi-finished products and components.
(2) High-temperature die & tool manufacturing: Used for high-temperature forging dies, metal extrusion dies, hot forming dies, die-casting molds, metal piercing plugs, and mandrels, improving wear resistance and deformation resistance under extreme operating conditions.
(3) Vacuum high-temperature equipment manufacturing: Used for heat shields, support structures, crucibles, and high-temperature load-bearing components in vacuum furnaces, vacuum heat treatment equipment, and vacuum sintering systems, ensuring long-term high-temperature stability.
(4) Semiconductor & crystal growth equipment manufacturing: Used for semiconductor thermal processing components; thermal field components, heat shields, and high-temperature structural parts in single crystal silicon growth furnaces and sapphire crystal growth furnaces.
(5) Aerospace & advanced industrial applications: Used for high-temperature aerospace components such as rocket engine nozzle throat liners, medical X-ray rotating anode shafts, corrosion-resistant components for glass melting equipment, and high-temperature components for nuclear industry applications.
