Most metal borides are hard; [41] however, a few stand out among them for their particularly high hardnesses (for example, WB 4, [42] [43] RuB 2, OsB 2 and ReB 2). These metal borides are still metals and not semiconductors or insulators (as indicated by their high electronic density of states at the Fermi Level ); however, the additional ...
The jewelry industry makes rings of sintered tungsten carbide, tungsten carbide/metal composites, and also metallic tungsten. [78] WC/metal composite rings use nickel as the metal matrix in place of cobalt because it takes a higher luster when polished. Sometimes manufacturers or retailers refer to tungsten carbide as a metal, but it is a ...
The Loop system splits the methane molecules in this metal "balloon" and captures hydrogen for fuel and carbon in the form of graphene [BBC] Graphene is the thinnest and strongest material ...
Their observations [9] were in the visible range where the strongest lines come from metals such as sodium, potassium, and iron. [10] In the early work on the chemical composition of the sun the only elements that were detected in spectra were hydrogen and various metals, [ 11 ] : 23–24 with the term metallic frequently used when describing ...
Even today it remains one of the most looked Steels worldwide. VG-1, Takefu stainless alloy steel. Popular steel in Japanese kitchen knives. [42] VG-2, high-carbon Mo stainless blade steel. VG-5, synergic effect of Mo and V makes carbide finer with added carbon and vanadium. VG-7/VG-8W, strengthens substrate and improves tempering performance.

Neodymium magnets are the strongest type of permanent magnet commercially available. They are key components of, for example, car door locks, starter motors, fuel pumps, and power windows. [166] Heavy metals are used in lighting, lasers, and light-emitting diodes (LEDs). Fluorescent lighting relies on mercury vapour for its operation.
