The metal for people with allergic reaction, titanium is anti-allergic, so you will never have a problem wearing titanium juwellery or watches.
Titanium is three times stronger than steel and almost half the weight, its natural colour is grey or white and is never found in its pure form. Titanium has to be extracted from other compositions like ore, ilmenite, ruthiel and Sphene.
Important sites where titanium is found are North-America, Russia, China, Africa and Australia.
Titanium is a very tough metal, and because of that very hard to fabricate juwellery from, it is hard to cut or shape, and can not be soldered. It needs other processing techniques than needed for gold or silver.
The melting point for titanium is very high, that's why very expensive tools are needed to cast titanium. Luckaly there are goldsmiths processing techniques and equipement to lasers and metal processing-machines to make juwellery ans watches.
Titanium is hypoallergic, even the most sensitive skin can take this, it also takes on the bodytemperature quickly, that's why is doesn't feel cold on the skin and gives extra wearingcomfort.
