•Introduction to Molybdenum Bar

Molybdenum bar are provided as random length pieces or cut into customers' desired lengths. There are three different surface processes or finishes which we provide, depending on the application of the molybdenum bar.

Surface:

Machined, centerless ground or black surface with lubricants and oxides. As per customer's demand.

1)Black Surface- Surface is "as swaged" or "as drawn"; retaining a coating of processing lubricants and oxides.
2)Cleaned- Surface is chemically cleaned to remove all lubricants and oxides.
3)Shiny finish- Surface is lathe shinny or polished.

Dimension:

Diameter - 2.0 mm to 100 mm and above

Length - up to 2500 mm

• Application

1)Molybdenum bars are mainly used in drawing thin molybdenum wire, molybdenum electrode and steel-making additives. Meanwhile, molybdenum bar is also widely used in the furnace industry for radiation screens, elements, and sintering trays

2) Molybdenum bars are used as electric light source parts and electric vaccum components

3) Molybdenum bars are used as heating elements and refractors in high temperature furnaces

4) Molybdenum bars are used as electrodes in glass and refractory fiber industry

5) Molybdenum bars are used as electrodes in the rare industry
