GMHI.M wide 2, GMHYM. One is a rare earth high temperature tantalum, niobium molybdenum,
The rare earth element is not counted as an impurity.
Dimensional tolerance standard for molybdenum wire production: National Standard GB/T4182—2003 “Molybdenum Wireâ€
Specification: Φ0.02mm--Φ12.0mm
Other uses: hook, core wire, grid side rod, lead wire, etc.
At present, domestic molybdenum wire manufacturers are: Shandong Guangming, Nanjing Diamond, Huaming, etc.
The characteristics of molybdenum wire as electrode wire:
1 super high tensile strength;
2 high surface finish, good stability and high cutting precision;
3 The elongation is small and the tension is small;
4 The volume of the roll is large, the wire diameter is consistent, the wire is not easy to break, and the life is long;
5 can increase high frequency power and improve roughing efficiency;
6 Accurate measurement, vacuum packaging, to prevent mildew and can be stored for a long time.
We supply various Solar Charge Controller with output voltage 13.8V or 12V/24V.
This series solar power controllers have a compact appearance, and can be installed easily.
Utilize advanced electronic controlling technology to transit solar power into electric power for electrical appliances, white at the same time store superfluous power in the cell. The intelligent CMOS chips inside give real time control as well as display the working status and providing multiple protections.
Iteal controller for solar power system.
