Vacuum-degassed 5N (99.999%) / 5N5 aluminum (Al, CAS 7429-90-5) evaporation pellets, granules, and slugs engineered for spit-free electron-beam and resistive thermal PVD.
Prepared specifically for high-vacuum electron-beam and resistive thermal evaporation, our 5N (99.999%) / 5N5 aluminum (Al, CAS 7429-90-5) deposition materials undergo vacuum degassing or high-temperature sintering to eliminate trapped volatiles and micro-voids that cause melt spitting and pinhole film defects.
Use intermetallic BN/TiB2, vitreous carbon, or Al2O3/BN e-beam crucible liners, or multi-strand twisted tungsten wire coils/boats for resistive thermal wetting. Supplied in cleanroom argon-flushed containers by weight (50 g to 1,000 g lots) or piece count, accompanied by the manufacturer's batch trace-impurity Certificate of Analysis.
