Manufacturing Process
Raw Material Preparation: High-purity molybdenum powder (≥ 99.95%)
Isostatic Pressing: Compact molybdenum powder into green bodies under high pressure
Intermediate Frequency Sintering: Sinter at 1800°C-2100°C in inert or vacuum atmosphere for densification
Precision Machining: Secondary processing (turning, milling, drilling, grinding) to achieve required dimensions
Heat Treatment (Optional): Solution or aging treatment to adjust strength and toughness based on application requirements
Note: This process achieves high density and low porosity, ensuring mechanical performance under extreme temperatures.

Selection & Usage Guidelines
Temperature Range: Standard MO1 tubes suitable for ≤1800°C; for >1800°C applications, recommend TZM (Mo-Ta-Zr alloy) or Mo-W alloys for enhanced creep resistance
Pressure Requirements: For high-pressure environments (≥10 MPa), wall thickness should be ≥5 mm or consider double-wall construction for increased safety factor
Corrosive Media: For prolonged exposure to strong acids (e.g., H₂SO₄) or alkalis (e.g., NaOH), recommend surface passivation or Mo-W composite coatings
Processing Methods: For dimensional accuracy requirements <0.1 mm, recommend precision turning + ultrasonic machining followed by vacuum annealing to eliminate residual stress
Quality Assurance: Factory inspection includes XRF composition analysis, density measurement, hardness/tensile testing, with material test reports provided
