| 3.7115 (DIN 17864 : 2012-03) | TiAl5Sn2,5 | 3.7115 | DIN 17864 : 2012-03 | DIN 17864 : 2012-03 replaced by DIN 17864 : 2026-03 | Replaced | Germany | TiAl5Sn2,5 | TiAl5Sn2,5 | 2.3 | ≤ 500 | 1) |
| 1) Remark: Chemical composition: DIN 17851 As alpha-titanium alloy, TiAl5Sn2.5 with the material number 3.7115 (see also TiAl5Sn2.5, material number 3.7114 according to the Werkstoff-Leistungsblatt der Deutschen Luftfahrt WL 3.7114) shows relatively high high-temperature tensile strength at temperatures of up to about 500 °C. The material is weldable, quenchhardenable and well forgeable. The cold-formability of this alloy is less good than that of unalloyed titanium or of titanium alloys with beta-phase content. |
