Packaging Each beam is composed of the molybdenum rods of the same grade, batch composition and specification. 3-5 parts are tied by soft plastic ropes or wires and then are wrapped by moisture-proof paper .At last they are packaged in wooden or cardboard boxes with Vibration isolation foam placed in . If there are special requirements, both sides can negotiate. During storage and transportation, molybdenum rod should be protected from moisture and violent collision. Products should be stored in a ventilated and dry acid-free atmosphere to prevent oxidation. Storage had better not be more than 6 months.
Black - Surface is "as swaged" or "as drawn"; retaining a coating of processing lubricants and oxides.
Ground - Surface is processed by grinding machine to remove all coating and to achieve precise diameter control.Main application: mainly used for electric vacuum components and electric light source partsMolybdenum mandrels
