Tungsten carbide is also naturally waterproof and tarnish-resistant — there is no chemical reaction with moisture, no darkening from skin contact, no gradual loss of colour. For Singapore's climate in particular, that corrosion resistance is not a luxury feature but a practical one. Tungsten carbide is four times harder than titanium and twice as hard as steel, 10 times harder than gold.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"5\"\u003eCare
