Molybdenum Spray Wire

FOTMA High-Purity Molybdenum Spray Wire: Superior Performance, Breakthrough in Single Weight, Boosting Efficient Surface Engineering 

We’re proud to introduce our next-generation high-purity molybdenum spraying wire, designed to meet the rigorous demands of surface engineering applications. As a leading materials provider, we are committed to delivering the highest quality products to help you achieve exceptional coating performance.

Exceptional Purity, Achieving Superior Performance:

Our molybdenum spraying wire is manufactured using advanced production techniques, ensuring exceptional purity. High-purity molybdenum wire offers the following significant advantages:

• Excellent Spraying Performance: The higher purity of the molybdenum wire allows for more uniform melting and better atomization during spraying, resulting in dense, even coatings, which improves spraying efficiency and coating quality.
• Superior Coating Adhesion: Coatings formed with high-purity molybdenum wire exhibit stronger adhesion to the substrate, ensuring the durability and longevity of the coating.
• Stable Chemical Properties: High-purity molybdenum demonstrates excellent resistance to corrosion, high temperature, and wear, ensuring the coating remains stable and reliable even in extreme environments.
• Low Impurity Pollution: High-purity molybdenum wire minimizes the introduction of impurities, reducing pollution to spraying equipment and the environment.

Breakthrough in Single Weight, Meeting Large-Scale Application Needs:

FOTMA’s molybdenum thermal spraying wire has achieved a significant breakthrough in single weight, going up to 25kg. This significant increase in single weight provides a more convenient solution for large-scale component surface spraying:

• Reduced Wire Change Frequency: The increased single weight reduces the frequency of changing the molybdenum wire during spraying, significantly improving production efficiency and reducing production costs.
• Meeting Large Component Requirements: The extra-large single weight of the wire meets the demand for continuous spraying on large components, ensuring consistency and uniformity of coating thickness.
• More Economical Choice: Fewer wire changes mean reduced downtime and material waste, providing a more economical solution for customers.

Wide Range of Applications:

FOTMA’s high-purity molybdenum spraying wire is suitable for various spraying processes, such as flame spraying, plasma spraying, and arc spraying, and is widely used in the following fields:

• Mechanical Manufacturing: Repairing worn parts, improving the hardness and wear resistance of components.
• Aerospace: Manufacturing high-temperature, wear-resistant components, improving the reliability of aircraft.
• Energy Industry: Spraying components used in high-temperature and high-pressure environments, improving equipment operating efficiency.
• Automotive Industry: Used for surface strengthening of components like piston rings and synchronizers.
• Medical Equipment: Used in the preparation of biocompatible coatings.
