Introduction

Corrosion resistance is a non-negotiable requirement for aluminum welds exposed to saltwater, chemical environments, or high humidity. Our specialized range of corrosion-resistant wires, dominated by high-Magnesium alloys like ER5183, is manufactured with precise control over trace elements (such as Iron and Copper) which can compromise corrosion performance. These wires are essential for long-term structural integrity in marine, chemical, and transportation applications.

Specification

Key PropertyHigh resistance to Stress Corrosion Cracking (SCC)
Material FocusER5183, ER5356, ER5556, and other 5XXX series alloys
CertificationOften certified by ABS, DNV GL, and CCS for marine environments
Alloy CompositionPrecisely controlled Magnesium (Mg) and Manganese (Mn) content
TestingSubjected to specialized corrosion and performance tests

Applications

  • Welding aluminum hulls, decks, and structural components for shipbuilding and yachts.

  • Fabrication of cryogenic tanks and pressure vessels handling corrosive media.

  • Use in offshore platforms, risers, and coastal infrastructure.

  • Joining aluminum piping and tanks in food and chemical processing plants.

FAQ

  • Q: Why are 5XXX series alloys generally more corrosion-resistant than 4XXX series?
  • A: The addition of Magnesium (Mg) in the 5XXX series forms a highly protective and stable oxide layer on the weld surface, providing superior resistance to general and pitting corrosion, especially in saltwater.
  • Q: What is the risk of using ER5356 on 5083 base metal at elevated temperatures?
  • A: Using ER5356 on 5083 base metal above 65掳C can create a microstructure susceptible to Stress Corrosion Cracking (SCC). For these applications, the lower Magnesium content of ER5183 is typically mandated.

Advantages

  • Extended Service Life: Weld joints resist degradation from saltwater and industrial chemicals, maximizing the asset's lifespan.

  • Regulatory Compliance: Meets the strict material requirements for marine classification societies globally.

  • Reliable Structural Performance: Corrosion resistance is paired with high tensile and yield strength, ensuring long-term structural safety.

  • Low Maintenance Costs: Reduces the need for costly maintenance and repair of corroded welds over time.

Payment and Shipping

  • Material Traceability: Full documentation (MTCs) to prove the specific chemical composition supporting corrosion resistance claims.

  • Packaging: Enhanced multi-layer sealing to prevent exposure to moisture during storage and transit.

  • Expert Consultation: Technical team can advise on the best corrosion-resistant alloy for a specific service environment.
