... there's more of it in Earth's crust than iron, interestingly.
Er...no there isn't. By an order of magnitude in fact - there is more Iron in the Earth's crust.
In Kg/Kg
Fe ( Iron ) 5.63×10−2 or 0.0563
Ti ( Titanium ) 5.65×10−3 or 0.00565.
Iron is the Fourth most abundant element in the Earth's crust, Titanium is the ninth.
But...cool light and I've asked for one for my Birthday - seeing as no one gave me any lights for Christmas. :mecry:
As for what Titanium is good for... ( GarageBoy!!! ...shakes fist...) as easilyled said - marine environments - propeller shafts etc - very resistant to saltwater corrosion. Stronger but lighter than steel. Human implants - all the hip joints my brother repairs his patients with are titanium based. Temperature resistant engine parts. Paints, drill bits, bicycles, golf clubs, watches, laptops, ...torches!
Oh, it's also the only element to burn in pure Nitrogen...must have a use.
