Product Overview

ER5154 is a magnesium-manganese alloyed filler metal containing 3.1% to 3.9% magnesium with controlled manganese addition of 0.15% to 0.5%. This composition provides higher as-welded strength compared to ER4043 or ER5356 when joining 5xxx series base materials. The manganese content refines grain structure in the weld deposit, improving ductility and fatigue resistance. ER5154 maintains mechanical properties in service temperatures from -196°C to 65°C, supporting cryogenic and marine applications. The alloy system exhibits natural aging stability without heat treatment requirements.

Key Specifications

Application Fit

ER5154 is designed for welding 5xxx series aluminum alloys, particularly in environments where corrosion resistance and low-temperature toughness are critical. Its magnesium content is optimized to prevent sensitization and intergranular corrosion, making it a preferred choice for marine and offshore structures.

• Marine Construction: Welded aluminum ship hulls, superstructure panels, offshore crew transfer vessels, LNG cargo tank fabrication.
• Cryogenic Equipment: Liquid natural gas storage tanks, oxygen/nitrogen transport vessels, low-temperature chemical processing lines.
• Heavy Transport: Aluminum tanker trailers, hopper rail cars, dump truck bodies, container chassis components.
• Structural Welding: Bridge decks, crane booms, modular building systems, seismic retrofit components.
• Defense Systems: Armored vehicle hulls, naval ship fittings, missile canister assemblies, tactical bridge modules.

Technical Performance Framework

• Strength Retention After Welding: Maintains 90-95% of base metal tensile strength in as-welded condition; no post-weld artificial aging required.
• Corrosion Resistance Profile: Passive oxide layer stability in salt spray testing exceeds 2000 hours per ASTM B117; resistance to intergranular attack in chloride environments comparable to 5154 base alloy.
• Thermal Stability: Mechanical property retention at elevated temperatures (150°C for 1000 hours) shows less than 8% reduction in ultimate tensile strength.
• Weld Metal Soundness: Controlled hydrogen content below 0.12ml per 100g aluminum produces radiographic Class I quality welds without centerline porosity or micro-fissuring.

Welding Procedure & Troubleshooting

For 1.2mm diameter wire, typical parameters are voltage 20-24V, current 120-180A, wire feed speed 4.5-7.5 m/min. Maintain contact tip to work distance of 12-18mm. Use push technique with 10-15 degree travel angle.

Joint Preparation: Remove surface oxide from weld zone using stainless steel brush dedicated to aluminum. Clean with acetone to eliminate hydrocarbon residue. For plate thickness above 8mm, preheat to 100-120°C to reduce cooling rate.

Porosity Control: Check shielding gas hose for leaks. Verify gas flow rate with rotameter. Store wire in humidity controlled environment below 55% RH. Replace contact tip if bore is worn beyond 0.1mm oversize.

Cracking Prevention: Avoid concave bead profiles by maintaining sufficient wire feed. For restrained joints, reduce interpass temperature below 150°C. Use backstep welding sequence for long seam assemblies.

Arc Stability Issues: Inspect drive roll groove condition. Replace Teflon liner after 150kg of wire consumption. Verify electrical connections at work clamp and torch. Use pulse waveform for vertical-up welding positions.

Post-Weld Inspection: Perform dye penetrant testing for surface cracks. Ultrasonic examination for internal defects. Conduct bend tests per AWS B4.0 specifications for procedure qualification.

Supply Chain & Storage Directives

Receiving Inspection: Verify spool condition and vacuum seal integrity. Check batch certificate for chemical analysis and mechanical test results. Reject any packaging showing moisture ingress or physical damage.

Warehouse Conditions: Store at 10-30°C with humidity range 30-55%. Maintain distance of 1m from exterior walls. Avoid stacking height exceeding 4 pallets. Use first-in-first-out inventory rotation.

Shelf Life Management: Unopened packaging: 36 months from manufacture date. Opened spools: use within 120 hours when stored in workshop environment. For long-term partial spools, use dry cabinet at 35-45°C.

Handling Protocol: Use clean cotton gloves when loading wire into feeder. Prevent contact with oil, grease or coolant mist. Do not set spools on dirty workshop floors. Return protective cover after each shift.

FAQs

What is the difference between ER5154 and ER5356?

ER5154 has lower magnesium (3.1-3.9%) compared to ER5356 (4.5-5.5%), offering superior resistance to intergranular corrosion and better stability at temperatures above 65°C. ER5356 provides higher tensile strength but is more susceptible to sensitization in marine environments.

Can ER5154 be used for cryogenic applications?

Yes, ER5154 maintains mechanical properties down to -196°C, making it suitable for LNG tanks and other cryogenic equipment. Its low-temperature toughness and corrosion resistance are key advantages.

What packaging options are available?

We offer D300 plastic spools (7kg), K355 drums (50kg), and pay-off bins (200kg). Custom packaging can be arranged based on your production needs.
