Titanium 6AL 4V ELI
1). Uses include armour plating on military vehicles, deep sea submersibles, computer chips, architectural reconstruction, nuclear storage systems, ballistic armour, medical devices, pacemakers, heart valves and many other applications.
2). It actually remembers it's original shape and will return to it even when severely deformed.
3). The energy required to produce one ton of titanium, from its ore, is 16 times that needed to produce one ton of steel, hence its higher market valuation.
4). Is now becoming one of the most favoured metal in the body piercing industry as it is only half the weight of stainless steel.
5). Can be anodised therefore offers a wide spectrum of surface colours, and is nickel free, making it ideal for initial piercings. Anodised titanium can be used in primary piercings as well as healed piercings; contrary to ill formed rumours, without detrimental effects.
6). Grade 23 surgical titanium (specification Ti6AL 4V ELI) is a grade recognised by standard societies world-wide for medical devices (societies include the international Standards Organisation in Switzerland and the ASTM in the USA). Heart valves, pacemakers, and replacement human body parts are now being made of grade 23 titanium and have been satisfactorily implanted into millions of people.
7). Its biocompatibility status is internationally respected: Grade 23 titanium has been designated an "F" prefix by the ASTM (F-136), which signifies its status as an approved medical grade material. No higher qualification currently exists.
8). The condition of the surface of titanium is of utmost importance for invasive applications. Titanium with a coarse surface is used in dental reconstruction because it will bond to bone without additional coating. Matt Titanium should not be used for body jewellery as badly polished titanium or a rough surface texture may be severely problematic in the piercing.
9). Grade 23 titanium has an oxide film almost three times as thick as Grade 1 titanium. The oxide layer passivates the material and makes it resistant to corrosion. The oxide layer also acts as a barrier to prevent the release of alloying elements. G23 titanium is also half the weight of niobium and significantly harder, resulting in a more durable colour performance.
10). At a recent international symposium on bio-materials titanium was placed as one of the most bio-compatible elements on earth, the other four being: Niobium, Zirconium, Tantalum and Platinum.
