100mm Pure Tungsten Rod,
Tungsten Rod 2.4 mm
wear-resistant high temperature resistant tungsten molybdenum alloy rods
Brand import molybdenum content or higher standard of molybdenum rods (%)
Trace impurities content (%) weight / / (kg/piece)
Molybdenum bar with high melting point, good thermal conductivity and low thermal expansion performance. Can under the high temperature, anti-oxidation, high strength.
Production and processing process
Forming, sintering, forging, machining overhang.
According to the material classification
Pure molybdenum rods, molybdenum content is more than 99.95% high temperature molybdenum rods, molybdenum lanthanum metal rods)containing lanthanum 0.4 ~ 1.2%, the molybdenum content is in addition to the impurity of allowance TZM molybdenum rods: Mo Ti - 0.5-0.5 ~ 0.12 Zr - 0.01 ~ 0.04 C. Points forging molybdenum rods, molybdenum rods and polished forging surface of molybdenum rods allow a slight oxide film, forging hammer marks; Polished surface of molybdenum rods present metallic luster, no oxidation phenomenon; Two surface without defects, such as delamination, crack, burr and vertical crack, etc
Dia (2 mm to 100 mm) * L, diameter. 16 (0.8 -) x length (mm). Diameter and length deviation are made according to standard GB4188-84
The surface of the
1, sintering molybdenum rods surface is silver gray metallic luster
2 have a layer of oxide, molybdenum rods, forging surface surface in black
3, polished molybdenum rods, is silver gray metallic luster
The surface oxide removal method
1, molybdenum product has the characteristics of easy oxidation. Need to remove the heavy oxide, please entrust the company or with strong acid (fluorine acid, nitric acid, hydrochloric acid, etc.), please pay attention to when operating.
2, mild oxide using abrasive cleaning agents, with a soft cloth or a sponge to wipe, and then rinse with warm water.
Wash the molybdenum products will lose luster, please note.
3 the packing of the molybdenum rods
Molybdenum rods need PE pearl cotton material separate packing, in appropriate cases, must fill gaps, to prevent vibration in transit, damage to the product.
4 application and use
Used in the manufacture of electric vacuum device and electric light source parts
Ion implantation suitable for processing parts
Used for high temperature heating element and high temperature structure parts
In the glass and refractory fiber industry used as a melting pot of the electrodes, at 1300 ℃ in the molten glass work, long service life
The rare earth industry is used as electrode
