Material Description

Material Number	Material Number (single)	Standard	Scope	Standard Status	Country	Predecessor	VDA 231-106 classification
3.7115 (DIN 17862 : 2025-05)	3.7115	DIN 17862 : 2025-05	Supersedes DIN 17862 : 2012-03	Valid	Germany	TiAl5Sn2,5	2.3	1)
1) Remark: High-alloy titanium material for round, square, hexagonal, octagonal and flat bars with an aspect ratio of width to thickness less than or equal to 3:1. Application: is preferably used as a construction material where weight-saving constructions of high stress or low damping, low electrical conductivity or non-magnetic behavior are required, e.g. mechanical engineering, precision mechanics, optics, measurement and control technology, electrical engineering, medical technology.
