Usage scenarios and applicability of ER5356 and ER5087 welding wires

ER5356 and ER5087 welding wires are commonly used in aluminum welding. Although they are both used for aluminum alloy welding, there are some significant differences in applicability and usage scenarios. The following is a comparative analysis of these two welding wires, including their chemical composition, performance characteristics and applicable scenarios.

1. Chemical composition
ER5356
Main ingredients: Aluminum-magnesium alloy, the magnesium content is usually between 3.5% and 5%.
Features: It has good corrosion resistance and weldability, suitable for high-strength welding.

ER5087
Main ingredients: Aluminum-magnesium-manganese alloy, the magnesium content is usually between 3.5% and 5%, and the manganese content is between 0.5% and 1.5%.
Features: Excellent corrosion resistance and mechanical properties, especially in marine environments.

2. Performance characteristics
ER5356
Strength: Welded joints have high strength and are suitable for withstanding high tensile and compressive forces.
Corrosion resistance: It has good corrosion resistance in general environments, but its performance may decrease in some special environments (such as marine environments with high chloride concentrations).
Weldability: Easy to control when welding, and the weld seam has good appearance.

ER5087
Strength: Better resistance to stress corrosion cracking, suitable for high temperature and corrosive environments.
Corrosion resistance: Excellent performance in marine environment, suitable for welding on ships and marine facilities.
Weldability: relatively easy to weld, but may have higher requirements on welding conditions.

3. Applicable scenarios
ER5356
Application fields: Mainly used in automobile, aerospace, construction, and general industrial welding.
Usage scenarios: Suitable for aluminum structures that require high-strength welding, such as the welding of high-load components and chassis components.

ER5087
Application fields: Especially suitable for marine engineering, shipbuilding and other highly corrosive environments.
Usage scenarios: Used for welding of marine structural parts, ship hulls, offshore platforms and other components that require corrosion resistance and strength.

ER5356 is more suitable for general aluminum welding, especially in structures requiring higher strength. ER5087 is more suitable for use in harsh environments, especially in marine engineering and highly corrosive situations. Depending on the specific application needs and environmental conditions, choosing the right welding wire will help improve the quality of the weld and the durability of the structure.
