Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If after grinding to electrode point
Welding electrodes, even tungsten-based, are classified as cored wire.
If diameter reduced by swaging
Size reduction processes make it a wrought article.
If chemically doped before import
Additivized tungsten (e.g., thorium compounds) becomes 'other metal compounds'.
