Annealed Molybdenum Tape

1. Basic performance: "physical anchor point" under extreme working conditions

    The characteristics of molybdenum (Mo) are released to the extreme after processing into thin ribbons:

    Thermal matching expert: The thermal coefficient (5.0 x 10-6) is extremely close to that of quartz glass, and it is the only medium to realize "gold and stone sealing".

    High temperature creep resistance: excellent shape stability in reduction up to 1800 °C.

    Excellent flexibility: After special annealing process, the molybdenum strip can withstand thousands of micro-thermal expansion and contraction cycles without fatigue cracks.

2. Chemical Composition

    We provide high purity molybdenum (99.95%) and doped molybdenum (such as TZM alloy) to suit different working life requirements.

    Execution standards: ASTM B387, ASTM B386 or customized standards based on customer-specific drawings.

3. Lean process: from dense blank to micron flexibility

    Our production chain ensures the consistency of performance of every inch of materials:

    High-pressure isostatic pressing and sintering: high-quality molybdenum slab with uniform density and fine grains.

    Multi-pass precision cold rolling: a four-high or six-high precision mill is used to compress the thickness tolerance to ± 0. 002 mm.

    Classified vacuum annealing: Unique recrystallization control technology, while ensuring ductility, prevents grain coarsening at high temperature leading to brittleness.

    Precision slitting: use diamond tools for micron-scale slitting to ensure that the edge is Burr-free.

4. Product Specifications and Basic Parameters (Technical Specifications)

    Thickness: 0.015 mm-0.2 mm

    Width: 0.5 mm-100mm

    Length: Coil supply (Spooling) or Cut-to-length on demand (Cut-to-length)

    Edge shape: Straight-edge or patented edge thinning/Knife-edge is used exclusively for glass sealing.

5. Surface treatment: cleanliness determines life

    Bright Annealed: Mirror texture, extremely low bleed rate, suitable for vacuum electronic devices.

    Pickled surface (Pickled): Microscopic roughness of the surface, which enhances the adhesion to certain coatings.

    Coating customization: Gold plating, nickel plating or surface graphitization treatment are available to meet extreme oxidation resistance or conductive needs.

6. Product core advantages: Why do senior engineers prefer our molybdenum strips?

    "Edge thinning" black technology: We make the edge of the molybdenum strip wedge-shaped through physical thinning, which effectively relieves the stress concentration during sealing and reduces the burst rate of the quartz tube by 30%.

    Non-contamination packaging: 100% ultrasonic cleaning, anti-static, anti-oxidation vacuum packaging to ensure out-of-the-box use.

    Isotropic consistency: The optimized rolling process ensures that the difference in transverse and longitudinal ductility is minimal, suitable for complex winding and welding.

7. Application field: covering high-end manufacturing territory

    Precision lighting: High pressure mercury lamps, halogen lamps, infrared heating lamps sealing leads.

    Audio & Communication: Cathode support and gate leads for high-end acoustic vacuum tubes (gallbladder machines).

    Semiconductor packaging and testing: as a flexible connection sheet and heat dissipation substrate for power devices.

    Photovoltaic industry: manufacturing conductive bus-bars for special thin-film batteries.
