Molybdenum rod

1, the appearance of forging molybdenum rod and polished molybdenum rod. Forging molybdenum rod surface is allowed and slightly oxidized Mo wrought traces, polished molybdenum rod surface is metallic luster, no significant oxidation.
2, grade according to chemical composition and for different purposes into GMPM. A 1G MHLM. A 2, GMHYM. One three three grades.
3, uses
GMPM. - 1 for the manufacture of electric vacuum parts, guide rods, electrodes, export lines, the heating electronic components. GMHI. M, 2, GMHYM. A 3 for the manufacture of tubes, electric light pinout strut, side rod, wire and so on.

GMHI. M. A 2, GMHYM. 3 is a rare high-temperature lanthanum, yttrium molybdenum, rare earth impurities without interest.
6, packing each beam Molybdenum tube by the same brand, batch number and specifications of molybdenum rods. With plastic or soft metal wire rope tied at 3-5. Outsourcing moisture-proof paper and then placed in isolation foam board or cardboard boxes inside. If you have special requirements determined through mutual consultation.
7, molybdenum rod storage in transit should prevent damp, not violent collision. Product should be stored dry ventilated, dry and free acid atmosphere place to prevent oxidation, storage period should not exceed six months.
