Molybdenum
Wholesale 99.95% High Purity Astm B386 Molybdenum Plate And Sheet
-
- Molybdenum plates are dark brown and silver gray metallic luster after alkaline washing.Can be produced according to the width, thickness, smooth surface, flat, no heavy skin, delamination, crack, crack edge, impurity clip and other defects.
-
- Molybdenum sheet refers to silver metallic sheets made of pure molybdenum, TZM molybdenum alloy, or high temperature molybdenum with its thickness ranging from.005 inches to .090 inches. It is used for fabrication of sintering boats, high temperature furnace heating elements and heat shields, because of its unique properties, which owns the characteristics of molybdenum.
-
- Molybdenum sheet can be divided into three categories according to its processing method, and each processing method has its own standard. They are hot rolling, cold rolling, and hot and cold rolling. Hot rolling marked by "R" ranges from 0.6mm to 4.0 mm in thickness. Cold rolling is marked by "Y". It is as thin as 0.02mm, and thick as 0.6mm. Hot and cold rolling is another processing method marked by "X", and its thickness is from 0.1mm to 0.5mm.
Surface Condition of Molybdenum Sheet
The surface condition of molybdenum sheet can be showed in different types, including shiny, matte, satin, or as-rolled condition, which is classified according to thickness and width parameters. Meanwhile, from the point of processing, the surface condition is also divided into polished one or non-polished one.
Heat Treatment of Molybdenum Sheet
Molybdenum flat products are rolled and annealed to provide the optimum condition for the ultimate use to customers. Heat treatment should be considered carefully, so that customers would feel satisfied to what they required from the manufacturer and product.

Appication |
Since the melting point of molybdenum has reached 2560oC, molybdenum sheet is widely used in reflection shield, cover plate applied in the sapphire growth furnace, reflection shield, heating tape, connecting pieces applied invacuum furnace, sputtering target applied in plasma coating film, and high temperature resistance boat. |

When temperature is beyond 1200oC, pure molybdenum will completely recrystallizate quickly. To improve the property, engineers added other elements to molybdenum to increase the recrystallization temperature. Studies suggested that the complete recrystallization temperature of molybdenum with doped chemical reached 1800oC.
