Grade 4xxx Alloys
Composition
The principle alloying element in Grade 4xxx is Silicon, accounting for up to 21.5% of these alloys by weight. Additional alloying elements include; ≤5.4 Iron, ≤5.0 Copper, ≤2.2 Nickel, ≤2.0 Magnesium, ≤2.0 Bismuth, ≤1.5 Manganese, ≤1.3 Zinc, ≤0.25 Chromium, ≤0.2 Titanium, ≤0.03 Lead, ≤0.01 Zirconium & ≤0.005 Boron
Characteristics
-
Generally used in welding rods and other joining methods
Weldability
Grade 4xxx alloys are well suited to use in welding rods and brazing sheets.
Common Forms
4xxx Series Alloys are commonly available in
-
