Product Overview
Cobalt Nickel Evaporation Materials (Co/Ni) is an alloy evaporation material intended for depositing multi-element metallic films. Unlike a pure element, an alloy may not evaporate congruently because its constituents can have different vapor pressures. As a result, source composition, evaporation method, deposition rate, and film-composition verification should be considered together; for very composition-sensitive films, co-evaporation from separate sources may be evaluated.
Evaporation Behavior and Process Considerations
Different alloying elements may evaporate at different rates because their vapor pressures are not identical. This can cause the source surface and deposited film to drift away from the nominal alloy composition during a run. For demanding composition control, film analysis, source replenishment strategy, or co-evaporation from separately controlled sources may be more reliable than assuming one alloy charge will evaporate congruently.

Source Form and Ordering Considerations
For quotation, provide material, purity, source form, particle or piece size, quantity, evaporation method, and any boat, basket, crucible, or e-beam hearth constraints. If the material will be used for a specific coating stack, sharing the intended film thickness or deposition application can help with source-form selection and packaging recommendations.
Frequently Asked Questions
Will Cobalt Nickel evaporate with the same composition as the bulk alloy?
Not necessarily. Alloy constituents can have different vapor pressures, so the vapor and deposited film may become enriched in the more volatile component as evaporation proceeds.
When is co-evaporation preferable to using a Cobalt Nickel alloy source?
Co-evaporation can be preferable when precise film composition must be maintained independently because separate source rates can be controlled and adjusted during deposition.
Can Cobalt Nickel be evaporated by electron beam?
Often yes, especially when the alloy requires high source temperature. The actual behavior depends on melting, segregation, evaporation rate, and whether the constituents remain sufficiently mixed in the melt.
How should film composition be verified for Cobalt Nickel?
For composition-critical films, analytical verification such as EDS, XRF, XPS, or another appropriate method should be used rather than assuming the film exactly matches the source alloy.
What source form is suitable for Cobalt Nickel evaporation?
Pieces, pellets, or granules may be supplied depending on the source holder. A stable charge geometry helps reduce movement and sudden changes in the heated surface.
What should I include in a Cobalt Nickel evaporation-material RFQ?
Specify alloy ratio, purity basis, source form and size, quantity, evaporation method, and the required film-composition tolerance if it is important.
