First known as „Manachite“ it was later given the name Titanium. Titans in the Greek mythology possessed extreme and superior strength. Titanium is the only element which combines the strength of steel with the weight comparable to Aluminum. In 1910, an American chemist was able to extract the metal from the ores and developed a method to produce pure Titanium. It had taken over a century from the discovery of titanium as an unpure form to develope a process which is currently still used to produce Titanium commercially. The rise of Titanium was driven by the need of more efficient materials. The positive and diverse influance of Titanium on mankind is uncomparable. Why Titanium? • Low density and a high specific strength resulting in a reduction of weight • Excellent corrosion resistance • Low modulus of elasticity • Good workability • Singular biocompatibility • Good capability for decoration and a very good image CP-Titanium and Titanium alloys have been proven to be technologically superior and cost effective materials, in a wide variety of applications. The classification is as follows: ALPHA group Grade 1, 2, 3, 7, 11 ALPHA-BETAgroup Grade 5, 9, 12, 23 BETAgroup Grade 19, 20 Superior strength-to-weight-ratio: The densities of titanium based alloys is between 4.43 – 4.84 g/cm³ depending on the quality. The yield strength range from min. 170 N/mm² for CP-Grade 1(deep drawing quality), over min. 828 N/mm² for Grade 5 and up to about 1240 N/mm² for heat treated BETA-alloys. The strength-to-weight-ratio of the Titanium based alloys are superior to almost all other metals. Excellent corrosion resistance: Titanium is immune to corrosive attacks by salt water or marine atmospheres and exhibits exceptional resistance to a broad range of acids, alkalis and industrial chemicals. Outstanding biocompatibility: Titanium alloys like Titanium Grade 5 ELI are solid, corrosion resistant, biocompatible and bioadhesive. This means, that these alloys are particularly adopted by the human body and enables the adhesion from cell to implant abetted by the low modulus of elasticity. The regeneration of the bones is stimulated by the desired stress of the surrounding tissue. Superior erosion resistance: Titanium offers superior resistance to erosion. Titanium is at least 20 times more erosion resistant than for example copper- nickel-alloys. Fabricating titanium: Titanium is not an exotic material requiring special fabrication techniques, one has only to pay attention, that Titanium is easy inflammable. It is handled much like other high- performance engineering materials, provided its unique properties are taken into consideration. Important differences between titanium and steel or nickel based alloys to be recognized are: • Titanium’s lower modulus of elasticity • Titanium’s higher melting point • Titanium’s lower ductility • Titanium’s propensity to gall • Titanium’s sensitivity toward contamination during welding Compensation for these differences allows Titanium to be fabricated, using techniques similar as used for austenitic stainless steel. Machining Titanium: Machining techniques and equipment for Titanium are similar as used for the austenitic stainless steel. Most important applications for Titanium and Titanium alloys: • Powerplant condensers and heat exchangers • Chemical processing • Desalination • Flue gas desulfurisation (FGD) systems • Wastewater treatment • Pulp and paper industry • Surgical implants • Medical industry • Aircraft industry • Automotive industry • General engineering • Watches, Jewellery • Architecture • And lots more Titanium is the only element that offers the unique combination of beauty, strength, light weight and biocompatibility.
