(1) GMPM. 1 is mainly used for wire EDM and Electric Light Source Materials molybdenum wire materials.
(2) GMDM. 4 is mainly used for alloying additives and molybdenum-based alloy materials.
4, the specification (1 5 ~ 30) × L (250 ~ 800) mm wherein GMDM. A 4-grade molybdenum plating length L (30mm mass fraction ≤ 5%
5, the chemical composition reference to national standards GB/T34622007 "molybdenum and molybdenum slab" of the relevant technical requirements of execution.
Molybdenum tube main features of indicators are as follows:

6, packing GMPM. A product with a wooden box or carton packaging, which has slotted foam board, GMDM. 4 with 100kg or 250kg iron drum rust, special requirements determined through mutual consultation.
7, storage products transport should be moisture collision. Stored in ventilated, dry place and no acid atmosphere. Prevent oxidation. Storage period should not exceed six months.
Molybdenum carbide has a high melting point and hardness, good thermal stability and mechanical stability, and excellent corrosion resistance and other characteristics. Molybdenum is a silvery white refractory metal, a melting point of 2615 ℃, density of 10.2 g / cm 3, the expansion coefficient is small, a special tube is almost the same coefficient of expansion of the glass. Molybdenum stable at room temperature is higher than 600 ℃, rapidly oxidized.
