The material. The alloys of titanium have the highest strength-to-weight ratio of any structural metal, about 25% greater than the best alloys of aluminum or steel. Titanium alloys can be used at temperatures up to 500°C; compressor blades of aircraft turbines are made of them. They have unusually poor thermal and electrical conductivity and low expansion coefficients. The alloy Ti 6% Al 4% V is used in quantities that exceed those of all other titanium alloys combined. The data in this record describes it and similar alloys.
Composition
Ti + alloying elements, e. g., Al, Zr, Cr, Mo, Si, Sn, Ni, Fe, V.

General properties
|
Adiabatic heating heats the air in the compressor to about 500°C, requiring the use of titanium alloys for the blades. (Reproduced with the permission of Rolls-Royce plc, © Rolls-Royce plc 2004.)
