Anodized Aluminum-Magnesium Plate vs. Stainless Steel: Performance Comparison and Selection Recommendations
In the construction sector, the competition between aluminum-magnesium plated panels and 304 stainless steel is intensifying. From a cost perspective, the price of aluminum-magnesium plated panels is 40% lower than 304 stainless steel, and they offer significant lifetime cost advantages—30 years of maintenance for aluminum-magnesium plated panels in coastal environments is only 65% of that for stainless steel. In terms of performance, aluminum-magnesium plated panels are comparable to stainless steel in chloride corrosion resistance (3.5% NaCl solution) but outperform in acid corrosion resistance (5% H₂SO₄ solution) with a 30% lower corrosion rate. Therefore, in projects that do not require resistance to strong acids and where cost control is essential, aluminum-magnesium plated panels present a more cost-effective value.
