Precision-tapered e-beam gun hearth liners in OFHC copper, purified & impermeable graphite, vitreous carbon, molybdenum, tungsten, alumina, and h-BN.
Electron-beam crucible liners act as a calibrated thermal barrier between your molten evaporant and the water-cooled copper hearth—dramatically boosting deposition rate at lower e-beam filament power while preventing cross-contamination across multi-pocket turrets. Machined to standard 15° side-wall tapers (2 cc mini-guns through 40 cc and 100 cc production pockets), our liners drop directly into Telemark, Temescal, Ferrotec, Leybold, Ulvac, and Angstrom e-beam sources.
Choose OFHC copper for high-thermal-transfer metals/oxides, high-strength impermeable graphite or glassy vitreous carbon for gold/aluminum/metals, molybdenum or tungsten for refractory/oxide melts, or alumina/h-BN ceramic inserts.

Reference values reflect typical sintered, fused, or wrought grades. Exact batch test figures are confirmed on your written quotation and accompanying lot Certificate of Analysis.
Specify e-beam gun brand/model OR exact pocket top OD × bottom OD × overall height × wall thickness (critical: keep ~0.5 mm clearance or match gun spec—graphite/ceramic thermal liners are deliberately slightly undersized so they thermally isolate from the water-cooled hearth!), liner material, evaporant metal/oxide, and pack quantity.
Include target quantity, destination country/postal code for express air freight calculation, and any special cleanroom bagging or certification requests.
