Core Material Advantages
High-Temperature Strength & Thermal Stability
With a melting point of 2623 C, molybdenum retains significant mechanical strength at elevated temperatures where conventional metals experience creep or structural failure. It exhibits high resistance to thermal deformation, ensuring dimensional stability during continuous thermal cycling in controlled atmospheres or vacuum environments.
Controlled Thermal Expansion & Precision
Maintaining a low thermal expansion coefficient (~ 4.8 x 10^-6 / K), molybdenum rolled sheets minimize dimensional shifts under fluctuating thermal loads. This is critical for high-temperature tooling, heat shields, and precision fixture plates that require tight working tolerances.
Machinability & Fabrication Versatility
Our rolled sheets are processed to achieve uniform microstructures, reducing hardness variations between production batches. They can be reliably fabricated using standard industrial methods:
CNC milling and turning
Wire EDM (Electrical Discharge Machining)
Laser and waterjet cutting
Stamping and blanking (for thin gauges)
Surface Finishes & Processing Services
Rolled Surface: Standard finish directly from the hot/cold rolling mill; suitable for general structural applications.
Ground Surface: Mechanically ground to remove rolling marks and achieve tighter thickness tolerances and improved flatness.
Polished Surface: Chemically or mechanically polished to minimize surface roughness (Ra) and reduce outgassing in vacuum applications.
Value-Added Processing: Custom cutting, shearing, CNC contour machining, and drilling according to CAD drawings.
Primary Industrial Applications
Vacuum Furnaces: Used as heating elements, radiation shields, hearth plates, and structural support frames operating under vacuum or inert gas protection.
Semiconductor & Electronics: Applied in high-temperature sintering boats, ion implantation components, and sputtering targets.
Specialized Tooling: Utilized in high-temperature press dies, mold inserts, and glass-working components where high thermal shock resistance is mandatory.
Quality Control & Documentation
Inspection Protocol: Every production batch undergoes strict verification, including chemical composition analysis (spectroscopy), dimensional checks (micrometer and coordinate measuring), and surface defect inspection.
Traceability: Full material lot traceability from raw powder compaction to final sheet delivery.
Documentation Support: Material Test Reports (MTR) provided in full compliance with industry and international standards.
