High Melting Point 70%Mo Molybdenum Tungsten Alloy Tube
1. High Melting Point 70%Mo Molybdenum Tungsten Alloy Tube Specifications:
The properties of tungsten and molybdenum metal are shared by the tungsten-molybdenum alloy, which also exhibits good high temperature stability, resistivity, and processing performance when protected by a vacuum or inert gas. Tests have shown that the alloy with 30% tungsten and 70% molybdenum has a unique anti-corrosion effect on liquid zinc.
2. Product Specifications of High Melting Point 70%Mo Molybdenum Tungsten Alloy Tube:
Out diameter | Wall thickness | Height |
|---|---|---|
| 26～750 mm | 5～30 mm | ≤1300 mm |
3. Physical and chemical properties of 70%Mo Molybdenum Tungsten Alloy Tube:
| Quantitative analysis | ||||||||||
| Element | W | Mo | Fe | Si | Ca | Mg | P | C | O | Al |
| Concentration(%) | 30 | 70 | 0.001 | 0.002 | 0.0006 | 0.0006 | 0.002 | 0.003 | 0.003 | 0.004 |
4. Product Features of 70%Mo Molybdenum Tungsten Alloy Tube:
A. High melting point
B. Very low vapor pressure (This is especially important for
applications in the refractory and vacuum industries.)
C. High physical strength at high temperature (for structural
parts in high temperature environments)
D. Creep resistance (high temperature load structural parts.
High dimensional stability. Such as: forging dies for large
aero-engine turbine blades.)
E. High elastic modulus
F. Very low coefficient of thermal expansion (important for
metal-ceramic structures, metal-semiconductor structures, metal-
graphite structures. For instance, future V-LEDs, which are
thought of as high-power LEDs, will use molybdenum or molybdenum
copper as the basis material.
G. Excellent electrical conductivity (metallic properties)
H. Excellent thermal conductivity (metallic properties)
I. Selective erosion resistance
5. Applications for 70% Molybdenum tungsten alloy tubes with a high melting point:
Tungsten-molybdenum alloy has excellent resistance to the corrosion
of liquid zinc and is used in the manufacture of agitators, pipes,
vessel liners and other components in the zinc smelting industry.
Tungsten-molybdenum alloy is more and more economical than pure
tungsten due to its good high temperature strength, similar
properties to tungsten and smaller specific gravity than tungsten,
Consequently, it has been used more and more in recent
years. It is widely used in high temperature rockets, high
temperature components in missiles, filaments of electronic tubes,
parts and other high temperature materials, including the thermal
field of sapphire crystal growth furnaces.
