Razumevanje 5052 Aluminijeva zlitina

Sestava:
5052 aluminum is an aluminum-magnesium alloy, with the following typical composition:

• Aluminij (Al): 95.7 – 97.7%
• magnezij (Mg): 2.2 – 2.8%
• Chromium (Kr): 0.15 – 0.35%
• Mangan (Mn): ≤ 0.10%
• Železo (Fe): ≤ 0.40%
• Silicij (in): ≤ 0.25%
• Baker (Cu): ≤ 0.10%
• Cink (Zn): ≤ 0.10%
• Drugi elementi: ≤ 0.05% vsak, ≤ 0.15% skupaj

General Properties:

• Moč: Moderate to high strength, especially in the H32 and H34 tempers.
• Odpornost proti koroziji: Odlično, zlasti v morskih okoljih.
• Sposobnost oblikovanja: Dobra sposobnost oblikovanja, especially when annealed.
• Varljivost: Weldable using all common welding techniques.

Temper Designations:

• H32: This temper is achieved by strain hardening and then stabilizing the material at a low temperature. The “H3” indicates strain hardening, and “2” indicates the degree of strain hardening.
• H34: Similar to H32, but with a higher degree of strain hardening. The “4” signifies a higher level of work hardening than the “2” in H32.
