Tin Molybdenum Wire

Process for molding the surface state: drawing, forging, and polishing.

Production dimension tolerance standard: national standard GB/T4182-2003: Φ0.02mm—Φ12.0mm

Apply

1. Used in profile cutting, H2 furnaces, heater rod guides, hooks, wire, lead, etc.

2. Employed in the production of high-temperature resistant equipment, such as furnace heating rods, brackets, guiding rods, etc.

3. for molybdenum furnaces and electron tube sockets in high-temperature hot fields, it is a fine-grained molybdenum rod. That is commonly used as heating material for high-temperature furnaces, heating screens for support materials, etc.

4. Additional uses include lead lines, hooks, core wires, and gate side rod supports.

In terms of physical and chemical properties, it is generally silver-grey or black in color (the surface is covered with graphite) and has a higher melting point, greater density, higher tensile strength, lower resistivity, smaller coefficient of thermal expansion, smaller elongation, good resistance to high temperatures and acids and bases. It should be noted that when heated in air, it reacts with oxygen; the overall performance of doped molybdenum wire is generally better than that of pure molybdenum wire.

In terms of production processes, it is a combination of hot and cold drawing processes that process high-temperature molybdenum raw materials into fine filaments. The production ways for doped molybdenum wire is a solid-liquid doping method, in which solid molybdenum dioxide is mixed with an appropriate amount of solid-solution metal elements and rare-earth oxides, then mixed evenly and finally subjected to hydrogen reduction, isostatic forming and pressing, sintering, spin hammer stringing, hot drawing, annealing, and cold drawing.

In terms of storage methods, that should generally be kept in a ventilated, cool place with low humidity and temperature to prevent it from oxidizing. In addition, poor verticality problems may occur if left for longer than 6 months.

You can try to tighten it again if the phenomena of poor contact between the molybdenum wire and the conductive block occur because it has been thinned and repeatedly stretched, reducing its tension. Tin molybdenum wire filament cannot be cut because as the molybdenum filament becomes thinner, the cutting gap also becomes thinner. This is very unfavorable for chip evacuation and makes it very simple to induce a short circuit in the cutting process. Try increasing the amount of dot line-cutting fluid. If the body of the wire-cutting tool is not clean, performance will suffer; make sure to promptly clean the bed.

Last but not least, changing the tin molybdenum wire with a fresh one is the simplest way to accomplish this. Molybdenum wire processing does not need to be overly cheap when cutting wires; less than 13 wires can actually be severed on their own. Because molybdenum wire is tin, wire-cutting processing efficiency will be slow, possibly too slow to preserve the capital, and it is always necessary to replace the old wire before cutting thick portions.
