tungsten bar molybdenum mesh welding brittleness

Molybdenum and molybdenum mesh network performance classification
Molybdenum network has a high temperature tungsten bar resistance, applied in a vacuum furnace heat treatment industry, the maximum temperature can reach 2200 ℃. Net producer of molybdenum lanthanum alloy wire is often used for the production of molybdenum
Raw materials, lanthanum alloy strength can be maintained. Molybdenum metal wire woven mesh has good thermal conductivity and a low coefficient of expansion, at a high temperature (1100 ~ 1650℃) high strength, as compared to tungsten mesh easier processing. tungsten carbide inserts The tube can be used as the gate and anode, the support materials, light, and for the production and casting Extrusion dies, spacecraft parts.
????Due to low temperature brittleness and molybdenum mesh welding brittleness and high temperature oxidation, so that the surface coated graphite milk to protect the molybdenum substrate, slow oxidation rate increase
Frequency of use. Mass production of molybdenum tungsten cubic molybdenum mesh network series series, molybdenum foil punching network series. The surface molybdenum mesh weave which can be divided into light and dark molybdenum Network
Color molybdenum net. The new molybdenum mesh products through mechanical leveler can improve their strength and flatness.
