1100 Aluminum is a commercial pure aluminum (Al content ≥99%) and a non-heat-treatable alloy (designated AA1100), characterized by high formability, electrical conductivity, and corrosion resistance.
Advantages
- Corrosion resistance (resistant to acids, alkalis, and humid environments)
- Electrical/thermal conductivity (59% IACS, 222 W/m·K)
- Excellent formability (elongation ≥35% in O temper)
- Low strength (tensile strength of H18 temper is only 24 ksi)
- Non-heat-treatable
- Poor high-temperature performance (long-term use ≤180°C)

FAQs
Q1: Can 1100 aluminum replace 3003 for chemical containers?
A: Yes in weak acid environments (pH>5), but 3003 with manganese offers better corrosion resistance; use 3003 + coating for strong acids.
Q2: Can H18 temper aluminum sheets bebent?
A: Shallow bending (R≥1.5× thickness) is possible with heavy equipment, but deep bending risks cracking; use H14 or O temper for deep bending.
Q3: Does ultra-wide plate (3800mm) affect flatness?
A: German SMS mill + CVCplus shape control ensures flatness ≤3 I-units (50% better than Chinese standards).
