Tungsten evaporation wire (99.99%, 1.0 mm diameter) requires water-cooled e-beam hearth or W/Ta support for deposition. E-beam evaporation is preferred; thermal evaporation is only suitable for thin charge or qualified setups.
- Deposition Source Compatibility: This evaporation material must be used with a water-cooled e-beam hearth or a tungsten/tantalum support (by RFQ) to ensure proper source loading and evaporation.
- Evaporation Method Restriction: E-beam evaporation is the preferred method; thermal evaporation is only suitable for thin charge or qualified setups due to the high melting point and material behavior.
- Melting Point Requirement: The high melting point of 3410°C requires the evaporation source to reach and sustain sufficient temperature for melting the wire.
- Procurement Verification: Confirm model, purity, form, size, pack size, and deposition-source compatibility before ordering to ensure proper process integration.
Why is e-beam evaporation preferred over thermal evaporation for this tungsten wire?
E-beam evaporation is preferred because tungsten's high melting point (3,410°C) and Z-ratio of 0.163 require controlled deposition conditions. Thermal evaporation is only suitable for thin charges in a qualified setup, as the source may not provide sufficient power or control for consistent film quality.
What deposition source hardware is compatible with this tungsten wire?
This tungsten wire is compatible with water-cooled e-beam hearths or tungsten/tantalum (W/Ta) support boats by RFQ. The specified wire diameter of 1.0 mm is designed for loading into these source configurations.
What should I confirm before ordering this tungsten evaporation material?
Before ordering, confirm the product model (AF-WWIR-4N1P0MM), purity (99.99%), form (wire), diameter (1.0 mm), pack size (100g, 500g, or 1kg), and deposition-source compatibility. This ensures the material matches your e-beam or thermal evaporation setup.
Tungsten wire evaporation material (99.99%, 1.0 mm dia.) with high melting point (3,410 °C) and density (19.35 g/cm³) is optimized for e-beam evaporation; thermal evaporation is limited to thin charges. Requires water-cooled e-beam hearth or W/Ta support, and buyers must confirm source compatibility and certificate requirements.
Positive
- 99.99% purity for consistent thin films: The 99.99% purity specification minimizes contamination in vacuum-deposited tungsten films, supporting reproducible electrical and mechanical properties in research-grade coatings.
- Precisely defined wire diameter of 1.0 mm: The 1.0 mm wire form facilitates controlled loading into e-beam hearths or thermal boats, ensuring uniform evaporation rates and reducing source-material waste.
Trade-offs
- Extremely high melting point (3,410 °C): Tungsten's 3,410 °C melting point necessitates specialized e-beam evaporation equipment; thermal evaporation is only feasible for very thin charges under qualified conditions, limiting process flexibility.
- Evaporation source hardware compatibility required: The material is recommended for water-cooled e-beam hearths or tungsten/tantalum support boats, requiring users to verify source geometry and submit RFQ for non-standard setups, adding procurement complexity.
