Aluminium-Copper 99/1wt% Evaporation Pieces 1-3 mm ATOMFAIR®

This evaporation material requires careful matching of deposition source hardware and process route to its melting point, density, and Z-ratio. The material is supplied with a purity specification requiring RFQ confirmation and is intended for thermal or e-beam evaporation under vacuum conditions.

• Evaporation Source Compatibility: Evaporation must be performed using Mo/W/Ta boat, graphite/alumina crucible, or e-beam hearth to avoid contamination or incomplete evaporation.
• Melting Point Constraint: The material has a melting point of 640°C, which must be considered when selecting the evaporation power and source material.
• Z-Ratio for Process Control: A Z-ratio of 1.00 is used for thickness monitoring during deposition, requiring correct calibration of the quartz crystal microbalance.
• Purity Confirmation: Total purity is subject to RFQ, and buyers must confirm the grade meets their film purity requirements before ordering.
• Physical Form and Size: The material is supplied as pieces of 1-3 mm, which must be compatible with the source geometry and feed mechanism of the deposition system.

This Al/Cu 99/1 wt% alloy evaporation material in 1-3 mm pieces is evaluated for vacuum thin-film deposition, where the defined composition and piece form support controlled co-evaporation of aluminum with a 1 wt% copper dopant, 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 process matching: The Al 99 wt%, Cu 1 wt% composition provides a fixed dopant ratio for reproducible film stoichiometry in thermal or e-beam evaporation, reducing trial runs for alloy target calibration.
• Piece form with 1-3 mm size range: The 1-3 mm pellet/piece size facilitates consistent loading into Mo/W/Ta boats, graphite/alumina crucibles, or e-beam hearths, minimizing source bridging and improving evaporation rate stability.

Trade-offs

• RFQ purity requires batch verification: Total purity is listed as RFQ (request for quotation), meaning the exact impurity profile is not pre-specified; buyers must request and review certificate of analysis to confirm suitability for high-purity film requirements.
• Evaporation source compatibility must be confirmed: The material requires matching to specific boat, crucible, or hearth hardware (Mo/W/Ta, graphite/alumina, or e-beam) based on melting point and wetting behavior; incorrect source selection may cause contamination or incomplete evaporation.
