Aluminum 2319
Nominal Chemical
Composition
INTRODUCTION
Aufhauser Aluminum 2319 was developed as a filler metal for alloy 2219. It is widely used in high strength structural, aircraft and truck body applications where superior resistance, formability and/or electrical conductivity are required. Especially suitable for use where superior resistance to stress corrosion cracking and excellent elevated temperature properties are desired. The alloy is heat treatable and provides higher strength and better ductility than the 4XXX filler alloys when welding 2XXX alloys.
APPLICATIONS
- Welding filler wire for high strength structures
- Aircraft and truck body applications
GENERAL INFORMATION
- Heat treatable
- Principle alloying elements: Copper, Manganese, Vanadium, Zirconium, Titanium
