The 0.4–1.0 mm 1100 aluminum sheet (pre-painted or fingerprint-resistant coated) is the most widely adopted pure aluminum material for microwave oven cavity liners, interior walls, turntable bases, waveguide covers and reflective surfaces in residential & commercial microwaves.
With purity ≥99.00%, 1100 provides:
Highest microwave reflectivity among common alloys (~95–97% at 2.45 GHz)
Outstanding pre-paint adhesion & uniform coating quality
Excellent formability for deep-drawn cavity shapes & embossed patterns
Lowest material cost while meeting all food-contact & safety requirements
Coating system:Pre-painted polyester (PE) or epoxy coating (15–25 μm),Fingerprint-resistant nano topcoat (optional),Food-safe, heat-resistant up to 250 °C continuous,Compliance: FDA 21 CFR 175.300, EU 10/2011, GB 4806,Warranty: 10 years indoor color stability & no odor generation

| Application |
Microwave Oven Cavity |
Core Benefits:
| Advantage | Detailed description |
|
Exceptional Microwave Reflectivity |
~95–97% at 2.45 GHz → efficient energy containment & fast heating. |
|
Fingerprint-Resistant & Easy-Clean |
Nano topcoat → fingerprints & grease wipe off instantly. |
|
Superior Corrosion Resistance |
Excellent in humid kitchen environments (no rust/pitting). |
|
Outstanding Formability & Deep-Drawing |
High elongation → complex cavity shapes without cracking. |
|
Significant Weight Reduction |
0.8 mm ≈ 2.16 kg/m² vs 0.8 mm stainless ≈ 6.4 kg/m² → ~66% lighter. |
|
Zero Odor & Flavor Transfer |
No metallic taste or off-odors even after prolonged heating. |

Q1: Why choose 1100 over 3003 or 5052 for microwave cavity liners?
A: 1100 has the highest microwave reflectivity (~95–97% at 2.45 GHz) due to its ultra-high purity, which improves heating efficiency. It is also 20–40% lower cost than 3003/5052, with sufficient corrosion resistance for indoor kitchen use. 3003/5052 are used when higher strength or extreme corrosion resistance is needed (rare in microwaves).
Q2: Does the coating withstand repeated heating cycles without peeling or odor?
A: Yes — food-grade heat-resistant PE/epoxy coating passes 500–1000 cycles at 200–250 °C with no peeling, cracking or odor generation. Real thermal cycling & odor test reports available.
Q3: Is the fingerprint-resistant coating effective & durable in daily use?
A: Yes — nano oleophobic topcoat hardness 2H–3H; fingerprints & grease wipe off with dry cloth. Abrasion & touch-test reports (ASTM D4060) provided.
Q4: Minimum order quantity & lead time for custom colors or coatings?
A: MOQ 3-5 tons (depending on width/color); standard white/silver 15–25 days; custom RAL or special fingerprint-resistant coating 25–35 days. Sample coils/sheets free with freight collect.
Q5: How does 1100 perform in high-humidity kitchens (e.g., Asia/Middle East)?
A: Excellent — no pitting, white rust or coating degradation in 90%+ humidity. Humidity chamber & long-term exposure data available.
Q6: Is 1100 suitable for microwave combination ovens (microwave + convection/grill)?
A: Yes — stable up to 250 °C continuous. Pre-painted versions maintain integrity in convection mode. Thermal cycling & grill-mode test reports provided.
