Aluminium-Copper 99/1wt% Evaporation Pieces ATOMFAIR®

Aluminium,1% Copper (Al/Cu 99/1wt%) evaporation material requires careful selection of deposition source hardware and process route to ensure successful thin-film deposition. The alloy's melting point (640°C), density (2.82), and Z-ratio (1.00) must be matched to the evaporation method and source geometry.

• Deposition-source compatibility: Use Mo/W/Ta boat, graphite/alumina crucible, or e-beam hearth as the evaporation source, confirmed for compatibility with the material's melting point and form.
• Evaporation method matching: Match the thermal/resistive or e-beam evaporation method to the material's behavior and required film properties.
• Purity and composition verification: Verify the material composition (Al 99 wt%, Cu 1 wt%) and confirm purity requirements via RFQ before ordering.
• Physical form and size assessment: Ensure the 3-6 mm piece size is appropriate for the deposition source loading geometry and process parameters.

This Al/Cu 99/1 wt% alloy evaporation material in 3-6 mm pieces is evaluated for vacuum thin-film deposition, where the defined composition and piece form support controlled co-evaporation of aluminum with 1% copper doping, but the RFQ-grade purity and unspecified trace element profile require buyers to verify batch-specific impurity levels for sensitive electronic or optical film applications.

Positive

• Defined alloy composition for doping control: The specified Al 99 wt%, Cu 1 wt% composition provides a reproducible source for introducing controlled copper doping into aluminum films during thermal or e-beam evaporation, enabling precise stoichiometry in alloy thin-film deposition.
• Piece form compatible with multiple sources: The 3-6 mm pieces are sized for loading into Mo/W/Ta boats, graphite/alumina crucibles, or e-beam hearths, offering flexibility across common evaporation hardware without requiring custom feed mechanisms.

Trade-offs

• RFQ purity requires buyer verification: Total purity is listed as RFQ (request for quotation), meaning the exact impurity levels are not pre-specified; buyers must request and review certificate data to confirm suitability for applications with strict contamination limits.
• Melting point and density constrain process window: With a melting point of 640 °C and density of 2.82 g/cm³, the material requires careful evaporation rate control to avoid spitting or composition drift, particularly in e-beam systems where local heating can cause preferential evaporation of the lower-melting-point aluminum phase.
