Molybdenum Disc Picture Inquiry & Feedback

Molybdenum disc, as one of molybdenum products, is shaped round to fit for parts of machine. Therefore, molybdenum disc shares properties of molybdenum products, which have many special features: excellent electric and thermal conductivity, lower thermal， expansion coefficient, higher bending strength, and so on. Following is a table to show its main features:

 Diameter (D)  4.5~102(mm)
 Thickness (H)  0.25~6.5(mm)
 Purity  ≥99.95%
 Thermal expansion
 coefficient (0~700℃)		  4.7~6.1*10-6/℃)
 Density  ≥9.90g/(cm3)
 Bending strength(20℃))  >420Mpa
 Resistivity  ≥6.26*10-6.cm(20℃))

The surface of molybdenum disc is smooth and cleaned, which is similar to molybdenum sheet, for molybdenum disc can be made from molybdenum sheet.

Molybdenum disc is made to the thyristor parts and its electric parts supporting base material, or be inserts of machines. Meanwhile, it is used as mounting material for power semiconductor devices due to its significantly lower cost and weight. Further applications include the use of molybdenum as heat sink bases in IC’S, LSI’S and hybrid circuits.

Here, the content of molybdenum disc should be considered:

Cleaned Molybdenum Wire

Cleaned molybdenum wire, namely white molybdenum wire, is molybdenum wire removes graphite coating on the surface by using the methods of electrolytic cleaning and hydrogen-sintered cleaning, and has a good bright and shiny surface. The diameter of cleaned molybdenum wire is ranging from 0.05mm to 3mm.

Molybdenum Bar

Pure molybdenum can be presented in many types. Molybdenum bar is one popular product made of molybdenum. Therefore, molybdenum bar shares the properties of molybdenum, which are high melting point, good thermal conductivity and low thermal expansion. At high temperature, they can resist oxidation and have high strength without any distortion during the procession, etc.
