Tungsten Lanthanum Alloy


If small quantities of lanthanum oxide (La₂O₃, 1.0~2.0%, 0.2~0.6%) are added to tungsten, its creep resistance is improved and the recrystallization temperature is increased. The machining performance for Lanthanum oxide-doped tungsten (Tungsten Lanthanum Alloy, W-La alloy) is better than pure tungsten. Tungsten Lanthanum Alloy is an ideal material for ion sources, welding electrodes and contact electrodes.

The regular content is for  W-La alloy 1.5% & 0.5% of lanthanum oxide .

Properties of lanthanum oxide-doped tungsten

-High melting point

-High thermal stability

-Good electrical conductivity

-Good thermal conductivity

-Low thermal expansion coefficient

Applications for W-La alloy

-Coils/boats for evaporating equipment

-Circular blanks for semi-conductor technology

-Power supply wires and anodes/cathodes for thermionic tubes

-Electrodes for plasma coating

-Electrodes for electric resistance welding

-TIG electrodes for shield gas welding, plasma welding

Products for W-La alloy
-Sputtering targets
-Components per drawings

Edgetech Industries LLC began offering Tungsten and other refractory metals products years ago. We specialize in providing worldwide customers with all types of Tungsten fabricated products (such as crucible, rod and bar, sheet and plate, etc.), heavy alloy that is mostly used as weights and shielding, composites (such as CuW, AgW) that is used for electrode contacts, and carbide alloy using as tools. Contact us at sales@edgetechmat.com for inquires and more information of tungsten.
