Core Material Properties & Processing Advantages
High-Temperature Dimensional Stability
Molybdenum retains structural integrity at extreme temperatures due to its high melting point (2620 C) and elevated recrystallization threshold.
• Thermal Expansion: The low thermal expansion coefficient (4.8 x 10-6/K) strictly limits dimensional shifting during repeated thermal cycling.
• Application Impact: Prevents micro-deformation in precision mold inserts, hot-runner components, and semiconductor tooling where thermal fluctuation compromises cavity accuracy.
Mechanical Strength & Uniform Tensile Performance
Controlled multi-stage wire drawing increases material density and structural uniformity across the entire spool length.
• Performance: Minimizes unexpected wire breakage during automated EDM operations and high-speed cutting.
• Straightness: Controlled residual stress ensures high straightness, reducing setup adjustments and machining deviations in micro-machined mold cavities.
Precision Diameter Tolerances (0.01 mm - 3.0 mm)
Strict dimensional control ensures predictable electrical discharge and mechanical behavior.

• Benefit: Reduces pitting, maintains a consistent spark gap, and produces superior surface finishes on complex injection mold cores and deep-draw cavities.
Manufacturing Process
Raw Material Selection: High-purity molybdenum powder is rigorously analyzed for chemical composition and particle size consistency prior to consolidation.
Powder Metallurgy: Isostatic pressing and high-temperature sintering yield fully dense, uniform molybdenum blanks free of internal voids.
Multi-Stage Drawing: Blanks undergo sequential cold-drawing through diamond dies, systematically increasing tensile strength and achieving strict target diameters.
Surface Treatment & Quality Audit: Wires are thoroughly cleaned to remove drawing lubricants, followed by batch testing for diameter tolerance, tensile strength, elongation, and surface integrity.
Quality Control & Inspection Protocols
To guarantee batch-to-batch repeatability for international industrial buyers, every production lot undergoes:
Chemical Analysis: Verification of Mo purity (99.95% / 99.97%) via advanced spectrometry.
Dimensional Checks: High-precision laser micrometers verify outer diameter and ovality across the entire spool.
Mechanical Testing: Tensile strength and elongation are measured to ensure full compliance with strict application thresholds.
Surface Inspection: Visual and microscopic checks confirm the complete absence of micro-cracks, oxide scales, or drawing residues.
