Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If thickness >0.1mm or surface treated
Thicker or worked sheets classify as worked rare-earth metals.
If phosphide-coated for specific reactions
Surface-treated with specific compounds reclassifies under phosphides.
If cut into calibration discs
Precisely cut for instruments becomes parts of analytical equipment.
