Tungsten-Lanthanum Alloy

  • 鎢鑭合金棒(英文名稱:Tungsten Lanthanum Alloy) 鎢鑭合金是在鎢基體中以彌散質(zhì)點(diǎn)存在的三氧化二鑭組成的合金。三氧化二鑭含量一般為0.5%~2.5%(質(zhì)量分?jǐn)?shù))。鎢鑭合金在擁有純鎢特性的同

                        Tungsten-Lanthanum Alloy
   
   Tungsten-Lanthanum 
alloy is an alloy composed of antimony trioxide in a tungsten matrix with dispersed particles. The content of antimony trioxide is generally from 0.5% to 2.5% (mass fraction). Tungsten-Lanthanum alloy has a higher recrystallization temperature than pure tungsten and has a longer service life than pure tungsten. 
   
    
 Tungsten-Lanthanum alloy rods are widely used in various fields. Such as the support rod and heating element of the high temperature furnace, electric light source parts and electric vacuum parts, ion implantation parts and so on.

Tungsten-Lanthanum alloy rods used in the field 
1. Tungsten-molybdenum heat shield support rods, 

2. Vacuum furnace support frame, carrier rods, rod heaters 
3. Physical vapor deposition tungsten parts 
 
 
Tungsten-Lanthanum alloy rod surface color classification
1. Sintered 
Tungsten-Lanthanum alloy The surface of the rod is silver-gray metallic luster; 
2. The surface of the black-skinned 
Tungsten-Lanthanum alloy rod has a layer of oxide and the surface is black; 
3. The polished
Tungsten-Lanthanum alloy rod is silver-gray metallic luster; 
4. The alkali-washed 
Tungsten-Lanthanum alloy rod, The oxide on the surface of the black-skinned Tungsten-Lanthanum alloy rod was washed away and was silver-gray. 
 
    Please tell us the diameter, length, surface condition, quantity, etc. of the tungsten-rhenium alloy rod you need, we will quote you.
