来自：154.201.*.*  QQ：	The Science Behind Tungsten Wedding Rings: Why They’re Nearly Indestructible Tungsten carbide’s reputation for toughness isn’t marketing hype—it’s materials science. Understanding its atomic structure and manufacturing process explains why these rings shrug off damage that destroys gold. Let’s break down the chemistry and engineering making tungsten a matrimonial superhero. Pure tungsten element W （atomic number 74） is a rare metal denser than lead with the highest melting point （3422°C） of any element. But it’s brittle alone. Jewelers use tungsten carbide （WC） formed by sintering tungsten with carbon at 1400–2000°C under pressure. The result: a ceramic-metal composite harder than steel titanium or gold. On the Mohs scale WC scores 8.5–9; only diamond （10） surpasses it. The crystal structure is key. Tungsten carbide forms a hexagonal lattice where carbon atoms nest between tungsten creating covalent bonds stronger than metallic bonds in gold. This resists deformation—gold
