Packing of Niobium Cb-752 Alloy Crucibles / Cups
Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.
ATTs’Niobium Cb-752 Alloy Crucibles / Cups are carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
