Molybdenum Wire And Rod ( Mo - 2623 °c )

 

Highly refined molybdenum chemicals are hydrogen reduced to molybdenum powder, having a purity of 99.9% minimum. The powder is isostatically pressed and sintered into rods of a uniform fine grained structure. The rods are then drawn down to the required size.

Moly rod / wire drawing is accomplished by coating with a graphite lubricant, heating to a red heat, and then drawing through tungsten carbide or diamond dies. The process is some times referred to as hot cold working, which means that, while the wire is still hot the temperature is still below the recrytsalization range accordingly as the crossectional area is reduced, strength and ductility are increased.

Molybdenum Sheet And Plate (Mo - 2623°C)

Highly refined molybdenum chemicals are hydrogen reduced to molybdenum powder, having a purity of 99.9% minimum. The powder is isostatically pressed and sintered into slabs of a uniform fine grained structure. The slabs are worked first by hot rolling and then by cold rolling to the thickness specified. Plate ( defined as flat stock with a thickness above 3mm ) is finished by grit blasting and stress relieving. Sheet ( having a thickness up to 3mm ) is generally finished by degreasing and stress relieving.
Molybdenum sheet is processed to obtain maximum ductility for applications involving bending, spinning, drawing or stamping. If the customer designates their specific application, we can supply the best material suited for their use.

Flatness

Molybdenum sheet or plate is inspected on a flat plate in accordance with ASTM B386-62t. All sheet or plate over 0.5mm thick will exhibit a maximum flatness of 4% and under 0.5mm thick being 5%.
This is defined as:
H / L x 100 = flatness, percent.
Where: H = Maximum vertical distance between a flat reference surface and the lower surface of the sheet or plate
L = Minimum horizontal distance between the highest point of the sheet or plate and the point of contact with the flat reference surface.)

Sizes and tolerances

Molybdenum sheet is available in thicknesses from 0.1mm to 4.75mm and the plate in thicknesses from 4.8mm to 38mm. Sheet and plate are supplied in either specific lengths or 250mm minimum random lengths. All plate and sheet are supplied in specific widths.

Finish

Sheet above 2.3mm thick and all plate are normally finished with a clean carbide free matt surface. Sheet 2.3mm thick and below are furnished with a clean bright surface.

Soundness

Sheet and plate are free of internal and external imperfections such as seams, cracks, surface checks, scale, inclusions and laminations.
