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 polishedTungsten-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.
