Titanium - where hardness is of the essence
Titanium is lighter and harder than stainless steel. But it is also three times as expensive, despite the fact that the Earth has comparatively large deposits of this metal. However, its extraction is difficult and expensive, because titanium bonds readily with other elements. This means that the material — which is also used for satellites — has to be laboriously separated from rock, sand and clay. The following types of titanium are in use.
Nickel Free
Pure Titanium
Titanium with a purity factor between 99.0 and 99.7%. Minimum residual quantities of nitrogen, oxygen, carbon and tungsten are unavoidable during production. Pure titanium is extremely difficult to work.
Beta Titanium (β Titanium)
Alloy of 75% titanium, 15% vanadium and 10% aluminum. This compound is just as light and durable as pure titanium, but is also particularly flexible.
Containing Nickel
Memory Titanium (NT)
Exceptionally flexible alloy of 50% titanium and 50% nickel silver. Used in the manufacture of eyeglasses. Contains nickel.
Titanium C
Electroplated nickel titanium, which can be worked liked conventional steel. That is why this kind of titanium is most common.
BOCCIA TITANIUM wristwatches and jewellery are made exclusively of pure titanium which contains no nickel. This is also true of the crowns, push buttons and clasps.
