In the intersection of precision manufacturing and high-temperature industry, the demands on material performance are extreme—it needs to withstand temperatures of thousands of degrees Celsius while maintaining ultimate strength and stable shape. When these requirements are concentrated in a metal wire, high-purity molybdenum wire becomes the irreplaceable answer.
FOTMA ALLOY, specializing in the deep processing of refractory metals, now offers 99.95% pure molybdenum wire. It is not only a “tool” for industrial production but also a “bridge” to achieve precision manufacturing and improve product performance.
I. Why molybdenum wire? What does 99.95% purity mean?
Molybdenum is renowned for its high melting point (2620℃), excellent high-temperature strength, moderate density, and low coefficient of thermal expansion. When it is presented in filament form and reaches a purity of 99.95%, its value is perfectly realized:
The Cornerstone of Stability: Extremely high purity means low volatility and low creep. Under long-term high-temperature environments, it resists softening and deformation, maintaining dimensional stability and ensuring the continuity and consistency of the production process.
Guaranteed Performance: Reduced impurity content directly improves the material’s recrystallization temperature, ductility, and tensile strength, giving molybdenum wire a longer service life and higher reliability under harsh operating conditions.
A Pure Source: For high-end applications such as semiconductors and sapphire growth, high purity ensures that the quality of the final product is not affected by contamination of the material itself.
II. Core Advantages: How can FOTMA high-purity molybdenum wire be your “preferred choice”?
Our products are designed to meet diverse needs from macroscopic support to microscopic processing.
1. Ultimate Purity (99.95%):
Significance: Ensures excellent and stable high-temperature mechanical properties and low volatility of the material from the source, fundamental to long-term, safe operation in high-end applications.
2. Superior Diameter and Surface Quality Control:
Precise Dimensions: We offer molybdenum wires in various diameters with strict tolerance control, ensuring smooth and precise operation during winding and threading processes.
Smooth Surface: Special surface treatment results in a smooth, crack-free, and burr-free wire surface, effectively reducing premature breakage at high temperatures and preventing contamination of the clean environment.
3. Excellent Overall Performance:
Good Winding Capabilities: Combining strength and toughness, it is easy to wind into complex spiral coils, heating elements, and other shapes.
Uniform Structure: Advanced wire drawing technology ensures uniform overall performance of the wire, with no weak points.
III. Application Scenarios: How can a single molybdenum wire connect high-end manufacturing processes?
