TIMET TIMETAL® 6-4 Titanium Alloy (Ti-6Al-4V; ASTM Grade 5) Rod or Thickness, <3.00 in, Annealed, Per ASTM B348
Categories: Metal; Nonferrous Metal; Titanium Alloy; Alpha/Beta Titanium Alloy

Material Notes: Medium To High Strength General-Purpose Alloy. Minimum tensile property data below are specific to Rod or Thickness, <3.00 in, Annealed, Per ASTM B348; other specific form/thickness entries are also available in MatWeb.

Industry Specifications: USA Aerospace: AMS 4911, 4928, 4932, 4935, 4954, 4965, 4967. Germany Engineering: 3.7165. Germany Aerospace: 3.7164. France: T-A6V. UK Aerospace Specifications BS TA. 10,11, 12, 13, 28, 56 DTD 5363.

Features: A versatile medium strength alloy, the "workhorse" TIMETAL 6-4 exhibits good tensile properties at room temperature, creep resistance up to 325°C and excellent fatigue strength. It is often used in less critical applications up to 400°C. TIMETAL 6-4 is the alloy most commonly used in wrought and cast forms. Palladium or ruthenium can be added for increased corrosion resistance. Most properties are affected by the microstructure, which is determined by the thermomechanical history. It is highly resistant to general corrosion in sea water. This alloy is available in most common product forms including billet, bar, wire, plate, and sheet.
