Titanium 6Al-2Sn-4Zr-6Mo
Ti 6AL-2Sn-4Zr-6Mo (Also known as Timetal(r)6Al-2Sn-4Zr-6Mo) is a heat treatable alpha-beta phase Titanium Alloy. A titanium alloy is combination of the element titanium alloyed during the melting process with other elements to enhance the electrical, thermal, or mechanical properties of the metal. Ti 6Al-2Sn-4Zr-6Mo is used in applications requiring a combination of high strength, light weight, corrosion resistance, and ductility. It is used extensively in applications in the Oil & Gas industry requiring materials that meet the specification NACE MR0175 or ISO 15156 and applications which demand higher strength than other heat treatable grades such as Titanium 6Al-4V ( Grade 5 ). The alloys is an Alpha-Beta phase alloy which is metastable and include a combination of both alpha and beta stabilisers, and which therefore can be heat treated to provide the desired combination of strength (beta phase) and ductility (alpha phase) depending on the application.
Because Ti6AL-2Sn-4Zr-6Mo (Ti6246)alloy is heat treatable, it is capable of achieving higher strengths than commercially pure titanum grades. Furthermore, the alloy's composition allows Ti 6AL-2Sn-4Zr-6Mo to achieve yield strengths in excess of 160ksi and Ultimate Tensile Strengths of 175ksi and typical elongation values of 11-14% and reduction in area of 35-37% in the Aged condition (Solution Treated & Aged).
6AL-2Sn-4Zr-6Mo has a UNS (Unified Numbering System) number of R56260 and a basic chemistry as follows:
Carbon <0.04% Nitrogen <0.04% Oxygen <0.15% Hydrogen <0.015% Iron <0.15% Aluminum 6.0% Vanadium 0.0% Tin 2.0% Zirconium 4.0% Molybdenum 6.0%
It has a density of .168 lbs per cubic inch (lbs/in3) and a modulus of elasticity (Young's Modulus) of 16.5.
The grade is manufactured in mill quantities by Timet Corporation (USA), and RTI Corporation (USA) and is distributed by Titanium Engineers Inc (USA) and Titanium Engineers Ltd (UK).
