Aluminum ER5554
ASTM AWS A5.10 ER5554 · EN S Al 5554 · JIS A5554WY · GB SAlMg-1
ER5554 is a moderate-magnesium Al-Mg-Mn filler covered by AWS A5.10 ER5554 (A5554WY, S Al 5554, SAlMg-1), formulated so that welds on 5454 base metal can run hot without the sensitization risk of higher-Mg fillers.

What is ER5554?
ER5554 is a moderate-magnesium Al-Mg-Mn filler covered by AWS A5.10 ER5554 (A5554WY, S Al 5554, SAlMg-1), formulated so that welds on 5454 base metal can run hot without the sensitization risk of higher-Mg fillers. It is sold as GMAW spool wire and GTAW rod, giving roughly 250 MPa tensile, 117 MPa yield, 17 % elongation, 60 HB and 134 W/m·K, with service to about 150 °C. It is not brazeable and needs a zincate pretreatment before plating; use ER5356 instead when only ambient-temperature strength matters. ER5554 has a density of 2.69 g/cm³ (0.0972 lb/in³), lighter than 67% of aluminum grades. It melts at 602°C (1,116 °F). ER5554 has a yield strength of 117 MPa (17 ksi) and a tensile strength of 250 MPa (36.3 ksi) — weaker than 78% of aluminum grades. Elongation at break is 17% and the elastic modulus is 70 GPa (10.2 Msi).

Working with ER5554
Is ER5554 easy to machine?
Weld beads machine like 5454 — gummy and prone to built-up edge; use sharp polished-flute carbide, high speed, low feed and generous lubrication.
Can ER5554 be welded?
Designed as GMAW/GTAW filler for 5454, 5154 and 3004 in service above 65 °C; use argon or Ar-He, clean oxide thoroughly, keep interpass temperature below ~120 °C and avoid dilution with Cu- or Si-bearing alloys.
Can ER5554 be formed, bent or molded?
Supplied as drawn rod/wire; interanneal between draws to keep ductility and avoid surface tearing that causes feed problems.

ER5554 — frequently asked
What is ER5554 used for?
ER5554 is typically used for 5454 tank trailers, elevated-temperature aluminum service and chemical process piping. In short: elevated-temperature 5000-series filler; sensitization-resistant Al-Mg; matched filler for 5454.
What is the yield strength of ER5554?
ER5554 has a typical yield strength of 117 MPa (17 ksi) and a tensile strength of 250 MPa (36.3 ksi) — weaker than 78% of aluminum grades. Strength varies by condition: see the 5 listed tempers.
Is ER5554 easy to machine?
Reasonably — machinability is rated fair (45/100, worse than 72% of aluminum grades). Weld beads machine like 5454 — gummy and prone to built-up edge; use sharp polished-flute carbide, high speed, low feed and generous lubrication.
Can ER5554 be welded?
Yes — weldability is rated excellent (92/100). Designed as GMAW/GTAW filler for 5454, 5154 and 3004 in service above 65 °C; use argon or Ar-He, clean oxide thoroughly, keep interpass temperature below ~120 °C and avoid dilution with Cu- or Si-bearing alloys.

Can ER5554 be formed, bent or molded?
Supplied as drawn rod/wire; interanneal between draws to keep ductility and avoid surface tearing that causes feed problems.
What is the maximum service temperature of ER5554?
ER5554 is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ER5554-AW and ER5554-H14?
AW is the default condition — default condition: properties of the deposited weld metal made with ER5554 wire, GMAW/GTAW, no post-weld heat treatment. H14: standard hard-drawn condition of layer-wound GMAW spool wire — column strength high enough for push-feeding through long guns. Yield strength is 117 MPa in AW versus 240 MPa in H14.
