Vanadium Aluminum Alloy AlV40 is a high-performance Intermediate Alloy that significantly improves the strength, high temperature resistance and corrosion resistance of Titanium Material by optimizing the ratio of Vanadium (V) to Aluminum (Al). The alloy is widely used in aerospace, automotive, precision tooling and specialty tooling applications, especially where lightweight design and demanding mechanical properties are required. Core Benefits and Performance Data
Excellent Mechanical Properties
Tensile strength: ≥450 MPa, superior to traditional aluminum alloys (e.g. 310 MPa for 6061-T6).
Hardness: HV 150-180, ensuring wear resistance and deformation resistance.
High temperature resistance: Long-term operating temperature up to 300°C, short-term resistance to 500°C (extrapolation based on data for similar vanadium alloys).
Chemical stability and corrosion resistance
Elemental vanadium (V) content up to 40% forms a dense oxide film which significantly improves resistance to acid and alkali corrosion (tested to ASTM G48 standard).
Corrosion resistance in salt spray environments is more than 3 times longer than pure aluminum.
Process Adaptability
Supports a variety of processing methods such as forging, extrusion, casting, etc., with a hardness uniformity error of <2% after heat treatment6.
Excellent welding performance, compatible with TIG/MIG process, weld strength up to 90% of the base material.
Fields of application
Aerospace: engine components, fuselage structures (lightweight and high temperature resistant).
Automotive industry: turbocharger housings, high-strength bolts (weight reduction and increased durability).
Mold manufacturing: aluminum alloy die-casting molds (resistance to occlusal wear and prolonged service life) .
Chemical equipment: corrosion-resistant reactors, pipe linings (adapted to acidic/alkaline media)
