Like cerium-tungsten, lanthanum-tungsten, zirconium-tungsten, and yttrium-tungsten electrodes, the thorium-tungsten electrode is a product made by doping metal tungsten with the corresponding oxide. Though it was the earliest used and remains the best-performing tungsten electrode for welding to date, its strong radioactivity has led to its gradual replacement by rare earth tungsten electrodes. Below is an introduction to the basic information about thorium-tungsten electrodes.

Like tungsten-copper, tungsten-molybdenum, and tungsten-nickel-iron alloys, tungsten-rhenium alloy (W-Re) is a type of high-density tungsten-based alloy that combines the excellent properties of both metal tungsten and metal rhenium. It is widely used in aerospace, aviation, maritime, military, and defense fields. Below is the basic information about this alloy:

Although both thorium-tungsten and cerium-tungsten electrodes are primarily made from metal tungsten and cerium-tungsten can often substitute for thorium-tungsten, differences in their dopants lead to variations in appearance, performance, production processes, and applications.

As a type of hard alloy, steel-bonded hard alloy combines the excellent properties of hard compounds and steel, primarily used in the manufacturing of wear-resistant parts and machine components. Below is an introduction to the basic information about this alloy material.
