The evaporation material must be used with deposition source hardware and process parameters matched to its melting point, density, and Z-Ratio. The pellet form factor and size range influence loading into boats or crucibles and require confirmation before use.
- Source Hardware Compatibility: Select a Mo/W/Ta boat, graphite/alumina crucible, or e-beam hearth based on the material's melting point and evaporation method.
- Pellet Size Handling: Confirm that the 3-6 mm pellet size range is compatible with the geometry of the deposition source.
- Process Parameter Matching: Use the listed melting point (640°C), density (2.82 g/cm³), and Z-Ratio (1.00) to calibrate the evaporation process and thickness monitor.
- Purity Confirmation: Verify the total purity (RFQ) against the film requirements before proceeding with deposition.
What does "total purity RFQ" mean for this Al/Cu 99/1wt% evaporation material, and how does it affect procurement?
"Total purity RFQ" indicates that the overall purity of the material is not pre-specified but is provided upon quotation request. This allows buyers to request a specific purity grade (e.g., standard, high-purity) tailored to their deposition requirements. Buyers should confirm certificate requirements and purity specifications before ordering to ensure the material meets their film quality standards.
Which evaporation sources are compatible with this Al/Cu 99/1wt% alloy pellet, and what considerations arise from the 1% copper content?
The material is compatible with thermal/resistive evaporation using Mo/W/Ta boats or graphite/alumina crucibles, as well as e-beam evaporation using a hearth. The 1% copper content, with a melting point of 640°C and density of 2.82 g/cm³, may lead to differential evaporation rates if source temperature is not carefully controlled. Matching the source hardware to the alloy's melting point and film requirements is essential for consistent deposition.
How does the 3-6 mm pellet size of this Al/Cu 99/1wt% evaporation material affect source loading and deposition uniformity?
The 3-6 mm pellet size is specified to facilitate consistent loading into standard evaporation sources such as boats, crucibles, or e-beam hearths. This size range helps ensure uniform material feed and reduces the risk of spitting or uneven evaporation during thermal or e-beam deposition. Buyers should confirm compatibility with their specific source geometry before ordering.
This Al/Cu 99/1 wt% alloy evaporation material in pellet form (3-6 mm) is evaluated for vacuum thin-film deposition, where the defined composition and pellet geometry support controlled co-evaporation of aluminum with 1% copper doping, but the RFQ-grade purity and unspecified trace element profile require buyers to verify compatibility with sensitive film applications.
Positive
- Defined alloy composition for doping: The Al 99 wt%, Cu 1 wt% composition provides a fixed stoichiometry for introducing controlled copper doping into aluminum films, eliminating the need for separate source calibration in co-evaporation setups.
- Pellet form supports source loading: The 3-6 mm pellet size is compatible with standard Mo/W/Ta boats, graphite/alumina crucibles, and e-beam hearths, facilitating uniform feed and reduced risk of source bridging during thermal or e-beam evaporation.
Trade-offs
- RFQ purity requires verification: Total purity is listed as RFQ (request for quotation), meaning the exact impurity levels are not pre-specified; buyers must confirm trace element content against film contamination tolerances before ordering.
- Evaporation method must be confirmed: The product supports thermal/resistive or e-beam evaporation by RFQ, but the optimal source hardware and process parameters depend on the specific deposition system and film requirements, requiring pre-order technical matching.
