More Information About ER5087 Magnesium Aluminum Welding Wire Suppliers

Enhanced Performance: Why ER5087 is Preferred Over ER5356 for 7xxx Series Aluminum

The structural welding of 7xxx series aluminum alloys (Al-Zn-Mg-Cu) presents significant challenges, primarily due to their high susceptibility to solidification cracking and the softening of the Heat-Affected Zone (HAZ). ER5087 Magnesium Aluminum Welding Wire is specifically engineered to overcome these hurdles. Hangzhou Kunli Welding Materials Co., Ltd., a high-technology enterprise with over 20 years of expertise, manufactures high-performance ER5087 magnesium aluminum welding wire that utilizes advanced alloying elements to ensure superior joint integrity in high-stress applications.

The Zirconium (Zr) Advantage

The fundamental difference between ER5087 and the standard ER5356 is the strategic addition of Zirconium (Zr). This element serves as a powerful grain refiner during the solidification process:

  • Grain Refinement: Zirconium promotes the formation of a fine, equiaxed grain structure. This inhibits the development of long, columnar grains that are prone to centerline cracking in 7xxx series welds.
  • Improved Crack Resistance: By refining the grain size, ER5087 reduces the "brittle temperature range" during cooling, effectively preventing hot tears that often occur when using standard ER5356 on high-strength alloys.
  • Better Mechanical Matching: While ER5356 is a versatile 5% Magnesium filler, it lacks the secondary alloying elements needed to maintain high joint efficiency in aerospace and high-speed rail components, areas where Hangzhou Kunli Welding Materials Co., Ltd. excels.

Technical Parameter Comparison: ER5087 vs. ER5356

Characteristic ER5087 (AlMg5Zr) ER5356 (AlMg5)
Key Alloying Elements 5% Mg + 0.1-0.2% Zr 5% Mg
Solidification Cracking Risk Low (Optimized for high-strength alloys) Moderate (Risk in constrained joints)
Microstructure Fine Equiaxed Grains Standard Columnar Grains
Corrosion Resistance Excellent (Marine & Chemical) Excellent
Typical Application 7xxx series, Cryogenic tanks, WAAM General 5xxx series structural welding
