Molybdenum Rhenium Alloy Foil Mo-47.5Re FAQs

Q1: What are the key material properties of Molybdenum Rhenium Alloy Foil Mo-47.5Re?

A1: Mo-47.5Re typically provides a combination of high strength, ductility, and corrosion resistance, particularly at elevated temperatures up to around 1,200°C. It exhibits thermal conductivity, a stable coefficient of thermal expansion, and enhanced creep resistance derived from the rhenium addition. Its fine-grained microstructure offers mechanical performance and allows for tight dimensional tolerances in foil form. The alloy’s low vapor pressure also makes it suitable for vacuum environments.

Q2: How can this Molybdenum Rhenium Alloy Foil Mo-47.5Re be processed or fabricated?

A2: Molybdenum Rhenium Alloy Foil Mo-47.5Re can be cold-rolled from ingots or billets, followed by intermediate annealing to refine grain structure and retain ductility. Manufacturers typically employ high-temperature vacuum annealing to remove residual stress and impurities. The alloy can be welded using electron beam or gas tungsten arc welding. Mechanical forming, such as deep drawing or stamping, is also feasible due to its ductility.

Q3: Which quality standards and certifications apply to Molybdenum Rhenium Alloy Foil Mo-47.5Re?

A3: Typical quality standards for Mo-47.5Re foil include compliance with ASTM B386 (Molybdenum and Molybdenum-Alloy Strip, Sheet, and Foil) and relevant AMS specifications, ensuring material purity, uniform thickness, and mechanical integrity. Manufacturers often maintain ISO 9001:2015 certification for quality management, verifying traceability and process controls. Third-party inspections and certifications, such as NADCAP for aerospace applications, may also be required for critical or high-reliability environments.

1. Manufacturing Process

Molybdenum Rhenium Alloy Foil Mo-47.5Re (Grade UNS R03700) undergoes a controlled sequence of production steps to achieve its mechanical properties. Engineers combine high-purity molybdenum and rhenium elements in precisely measured ratios, maintaining the 47.5% rhenium composition throughout the alloy. The mixture is then melted under vacuum to eliminate impurities before being solidified, forming ingots with uniform chemical distribution.

Tight rolling operations shape the ingots into thin foil with customised dimensions. Any deviations in thickness are corrected through intermediate annealing and additional rolling passes. This procedure ensures dimensional accuracy and refines the microstructure, resulting in foil that maintains ductility, fracture toughness, and resistance to high temperatures.

2. Applications in Advanced Industries

Applications for Mo-47.5Re foil extend across aerospace, energy, and medical fields. Within these sectors, the foil’s ability to retain strength at extreme temperatures makes it suitable for rocket nozzles, satellite propulsion systems, and X-ray tubes. By providing resistance to thermal shock, it helps minimise component failures during operational cycles.

Mechanical stability and minimised creep rates enable this foil to excel in specialised environments. Whether implemented in nuclear energy reactors or used in instrumentation for particle accelerators, the Grade UNS R03700 alloy’s thickness allows engineers to tailor the material to meet performance requirements in demanding projects.
