Chemical Composition (Weight %)

The "Mg3" in the name signifies a nominal 3% Magnesium content, which provides its strength and corrosion resistance.

• Magnesium (Mg): 2.6% 3.6%

• Manganese (Mn) + Chromium (Cr): 0.1% 0.6%

• Silicon (Si): max 0.4%

• Iron (Fe): max 0.4%

• Aluminum (Al): Remainder

Common Tempers for Sheets & Plates

• O: Annealed (softest, best for deep drawing).

• H111: Some work hardening from shaping (e.g., leveling) but essentially soft.

• H22: Work-hardened and partially annealed to "quarter-hard."

• H24: Work-hardened and partially annealed to "half-hard."

Applications

1. Marine: Ship hulls, decks, and fishing equipment due to salt-water resistance.

2. Automotive: Body panels and internal structures (excellent weldability).

3. Industrial: Welded pressure vessels, chemical tanks, and food processing equipment.

4. Flooring: Frequently used for "treadplate" (checker plate) because of its durability and slip resistance.
