Suitability for being joined by:
Soldering/Good
Brazing/Good*
Oxyacetylene Welding/Not Recommended
Gas Shielded Arc Welding/Not Recommended
Coated Metal Arc Welding/Not Recommended
*Since brazing is performed at temperatures within the hot-short range, strain must be avoided during the brazing and cooling of this alloy.
The values listed above represent reasonable approximations suitable for general engineering use. Due to commercial variations in composition and to manufacturing limitations, they should not be used for specification purposes. See applicable A.S.T.M. specification references.
