Baoji Aulister Import and Export Co., Ltd. is a professional non-ferrous metal processing and sales manufacturer based in Baoji, Shaanxi Province, China—renowned as the “Chinese Titanium Valley” for its rich rare metal resources and strong industrial chain. We specialize in the production and supply of titanium, tantalum, niobium, molybdenum, nickel, target materials, and precision machined components. With advanced production facilities, strict quality control systems, and extensive industry experience, we deliver high-quality non-ferrous metal products to global customers, catering to diverse industrial needs with reliable performance and competitive pricing.
Molybdenum alloy bars are high-performance refractory metal products made from molybdenum (Mo) as the base element, blended with alloying elements like titanium (Ti), zirconium (Zr), and rhenium (Re) (e.g., TZM molybdenum alloy: Mo-Ti-Zr-C). Manufactured via powder metallurgy, high-temperature sintering, hot forging, rolling, and precision machining, these bars exhibit exceptional physical and mechanical properties that pure molybdenum cannot match.

Ultra-High Melting Point & High-Temperature Stability
With a melting point of 2,620°C, our molybdenum alloy bars maintain stable mechanical properties at temperatures up to 1,900°C, far outperforming steel and ordinary alloys. TZM alloy, our flagship product, has a recrystallization temperature of 1,300°C (200°C higher than pure molybdenum), ensuring no softening or deformation under extreme high-temperature conditions.
Superior Mechanical Strength
Our molybdenum alloy bars deliver excellent tensile strength (750 MPa at room temperature, 400 MPa at 1,000°C) and elongation (20% at both room and high temperatures), offering outstanding resistance to creep, fatigue, and impact. Even under long-term high-temperature stress, they retain structural integrity, ideal for heavy-duty industrial applications.
Low Thermal Expansion & High Thermal Conductivity
Featuring a low thermal expansion coefficient (5.2×10⁻⁶/K) and high thermal conductivity (140 W/m·K), our bars minimize dimensional changes during rapid heating/cooling and efficiently dissipate heat—critical for precision equipment and high-temperature furnaces.
Excellent Corrosion Resistance
Resistant to corrosion by molten glass, molten metals (e.g., zinc), acids, and alkalis in vacuum or inert gas environments, our molybdenum alloy bars outlast stainless steel in harsh chemical and high-temperature environments.
Precision Machinability & Customization
We produce molybdenum alloy bars in diameters from 1mm to 150mm, with strict dimensional tolerances (±0.01mm) and smooth surface finishes. Available in various grades (pure Mo, TZM, Mo-Re) and custom lengths, they can be machined into bolts, electrodes, heat sinks, and other precision components.
Our molybdenum alloy bars are widely used in:
Aerospace & Defense: High-temperature components for rocket engines, missile parts, and aircraft gas turbines.
High-Temperature Furnaces: Heating elements, support rods, and heat shields for sapphire crystal growth furnaces, vacuum furnaces, and glass melting furnaces.
Electronics & Semiconductors: Target materials, electrodes, and heat sinks for semiconductor devices and power electronics.
Medical Industry: High-purity molybdenum components for medical imaging equipment and surgical instruments.
Metallurgy & Glass: Stirrers, pipes, and container liners for zinc smelting and glass production.
1. Factory Direct Supply: As a professional manufacturer, we control the entire production process from raw material procurement to finished product delivery, ensuring stable quality and competitive prices.
2. Strict Quality Control: All products comply with ASTM B387 and international industry standards, with 100% inspection for dimensions, hardness, and microstructure. We provide complete test reports and quality certificates.
