What is 5654?
5654 is a high-purity, low-copper Al-Mg alloy (A95654, EN AW-5654, AlMg3.5(A)) supplied as H19 filler wire and as sheet in O, H112 and H32-H38. It is chosen for hydrogen peroxide and other high-purity chemical service where copper contamination is unacceptable, offering 115 MPa yield, 240 MPa tensile, 25 % elongation, 58 HB, 126 W/m-K, 32.4 % IACS, formability 92 and a corrosion-resistance score of 87. Service is limited to 65 C to avoid Mg2Al3 grain-boundary sensitisation, and machinability is low (35). 5254 is the nearest alternative for peroxide duty. 5654 has a density of 2.66 g/cm³ (0.0961 lb/in³), lighter than 84% of aluminum grades. It melts at 593°C (1,099 °F). 5654 has a yield strength of 115 MPa (16.7 ksi) and a tensile strength of 240 MPa (34.8 ksi) — weaker than 79% of aluminum grades. Elongation at break is 25% and the elastic modulus is 70.3 GPa (10.2 Msi).

Working with 5654
Is 5654 easy to machine?
Gummy in O/H112 — use sharp polished high-rake carbide, high speed, generous soluble-oil or alcohol-based lubricant; strain-hardened tempers chip much better.
Can 5654 be welded?
Excellent GTAW/GMAW behaviour with 5654 or 5356 filler; keep interpass temperature low and avoid prolonged >65 °C exposure to prevent Mg2Al3 grain-boundary sensitisation.
Can 5654 be formed, bent or molded?
Very good cold formability in O/H32; allow generous bend radii in H36/H38 and consider inter-anneal at 340 °C for severe drawing.

5654 — frequently asked
What is 5654 used for?
5654 is typically used for hydrogen peroxide storage tanks, high-purity chemical piping welds and semiconductor fluid handling. In short: copper-free peroxide-service alloy; highest formability here; filler wire and sheet.
What is the yield strength of 5654?
5654 has a typical yield strength of 115 MPa (16.7 ksi) and a tensile strength of 240 MPa (34.8 ksi) — weaker than 79% of aluminum grades. Strength varies by condition: see the 7 listed tempers.
Is 5654 easy to machine?
Not especially — machinability is rated fair (35/100, worse than 86% of aluminum grades). Gummy in O/H112 — use sharp polished high-rake carbide, high speed, generous soluble-oil or alcohol-based lubricant; strain-hardened tempers chip much better.
Can 5654 be welded?
Yes — weldability is rated excellent (92/100). Excellent GTAW/GMAW behaviour with 5654 or 5356 filler; keep interpass temperature low and avoid prolonged >65 °C exposure to prevent Mg2Al3 grain-boundary sensitisation.
What surface finishes work on 5654?

Can 5654 be formed, bent or molded?
Very good cold formability in O/H32; allow generous bend radii in H36/H38 and consider inter-anneal at 340 °C for severe drawing.
What is the maximum service temperature of 5654?
5654 is rated for continuous use to about 65°C (149 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 5654-O and 5654-H38?
O is the default condition — default for formed sheet/plate in hydrogen-peroxide and chemical tankage where maximum ductility and lowest sensitisation risk are wanted. H38: maximum strain-hardened strength for flat or minimally formed parts; bending is limited and SCC caution applies. Yield strength is 115 MPa in O versus 270 MPa in H38.
How much does 5654 cost?
5654 is a premium-cost aluminum ($$$), cheaper than about 51% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
