Description

Titanium DIN TiAl6Sn2Zr4Mo2Si is a two-phase, Alpha Beta Alloy. It is usually used in the annealed or solution treated and aged conditions. It’s a heat treatable, high strength alloy with lower toughness and ductility than Titanium Grade 5 (6Al-4V) and it’s difficult to weld. Cold forming of DIN TiAl6Sn2Zr4Mo2Si is difficult because of its high strength. This grade can be welded by the inert gas shielded, fusion welding process but the heat effected area will have less ductility and toughness than the parent material. This grade is primarily used for airframe and jet engine parts, rocket engine cases and ordinance components.

This material data has been provided by WIAM.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
