The 1100-H14 and 1100-H18 aluminum plates are commercially pure aluminum products designed specifically for commercial and passenger automotive manufacturing. Containing a minimum of 99.00% aluminum, these plates deliver high thermal conductivity and excellent corrosion resistance under harsh environmental conditions. The H14 temper indicates the metal is strain-hardened to a half-hard condition, providing a precise balance of formability and mechanical strength.
The H18 temper represents a full-hard condition, offering maximum tensile strength without additional thermal treatment. Manufactured according to the active ASTM B209 standard, these aluminum plates function effectively as automotive heat shields, bus body exterior panels, and heavy-duty trailer floors. At GNEE, we supply these materials globally to meet the exact dimensional and performance specifications required by major automotive OEMs.

1. Uses and Applications
The 1100-H14 and 1100-H18 aluminum plates integrate into various commercial and passenger vehicle components, providing necessary material properties for everyday automotive manufacturing demands.
- Exhaust Heat Shields: The H14 temper plates operate effectively at continuous temperatures up to 150°C, reflecting radiant heat away from the vehicle cabin. Major OEM automakers utilize the 0.5mm to 1.5mm thickness range to stamp complex shield geometries without experiencing material fracture during the pressing process.
- Bus and RV Body Panels: Manufacturers apply 1100-H18 aluminum plates for exterior side panels requiring superior surface hardness. The 1.2mm to 2.0mm thick plates maintain structural integrity against wind loads while allowing surface treatments like fluorocarbon spraying or anodizing to withstand daily environmental exposure.
- Commercial Trailer Floors: Heavy-duty transport trailers incorporate patterned 1100-H14 plates to provide critical anti-slip properties and cargo support. Using 3.0mm to 5.0mm thicknesses, these floors deliver a yield strength of 103 MPa (15 ksi), resisting permanent deformation under standard pallet weights during daily logistical operations.
- Battery Thermal Management: Modern electric vehicles integrate 1100 aluminum alloy sheet specifications for cooling channels due to a thermal conductivity of 222 W/m·K. The H14 temper allows precise folding and laser welding, preventing coolant leaks while transferring heat away from battery cells operating above 45°C.
2. Key Benefits and Advantages
Utilizing 1100-H14 and 1100-H18 aluminum plates yields measurable technical advantages, ensuring compliance with strict automotive industry standards regarding weight, thermal dynamics, and structural longevity.
- High Thermal Conductivity: Containing over 99.00% pure aluminum, both tempers achieve rapid heat dissipation rates necessary for under-hood applications. This physical property reduces localized temperature spikes in automotive exhaust systems by up to 30%, actively protecting adjacent plastic components and wiring harnesses from long-term thermal degradation.
- Superior Corrosion Resistance: The absence of complex alloying elements prevents galvanic corrosion when exposed to road salt and moisture. This inherent resistance eliminates the need for heavy protective coatings, extending the operational lifespan of exterior bus body panels and underbody heat shields by approximately 15% to 20%.
- Optimal Formability: The H14 half-hard state offers excellent cold-working capabilities, permitting bend radii as tight as one times the material thickness. Automotive stamping plants utilize this flexibility to produce complex 3D shapes for custom heat shields with manufacturing scrap rates consistently maintained below a 2% threshold.
- Weight Reduction: With a precise density of 2.71 g/cm³, 1100 aluminum plates are 65% lighter than standard automotive steel panels of identical dimensions. Replacing traditional steel heat shields with 1100-H14 aluminum directly reduces the overall vehicle curb weight, lowering fuel consumption and greenhouse gas emissions significantly.

3. Delivery, Inspection Standards, and Packaging
GNEE executes stringent logistical and inspection protocols to guarantee that all 1100-H18 aluminum plates arrive at assembly facilities intact and fully compliant with technical specifications.
Standard Compliance Verification: All shipments comply strictly with the active ASTM B209 / ASME SB209 standards for dimensional tolerances and material properties. The documentation package includes a Mill Test Certificate verifying the chemical composition of ≥99.00% aluminum alongside the mandated 103 MPa (15 ksi) yield strength metrics.
Production and Lead Time: Our manufacturing lines support an average delivery lead time of 15 to 25 days following order confirmation. Standardized dimensions like 1000mm width in the H14 state are available from inventory, ensuring rapid logistical dispatch for urgent OEM commercial vehicle assembly line requirements.
Moisture-Proof Packaging: Aluminum sheets receive an initial layer of neutral plastic film, followed by heavy kraft paper wrapping to block moisture ingress. Desiccant packets are placed inside the packaging to maintain internal humidity levels below 30% during ocean transit, preventing surface oxidation or water stains entirely.
Secure Palletization: The packaged plates are secured onto fumigated wooden pallets using high-strength steel strapping. Edge protectors are installed on all four corners to distribute strap tension evenly, ensuring the 0.2-300mm thick plates sustain zero physical deformation or structural edge damage during forklift handling operations.
4. Product Quality Testing
Rigorous laboratory testing procedures validate the mechanical and chemical integrity of the 1100-H14 1100-H18 aluminum plates, ensuring complete reliability for demanding automotive manufacturing environments.
Chemical Spectrometry Analysis: Technicians utilize optical emission spectroscopy to measure the exact elemental composition of each production batch. This testing guarantees the aluminum content exceeds 99.00% and confirms that combined silicon and iron impurities remain strictly below the 0.95% maximum threshold permitted by current technical specifications.
Mechanical Tensile Testing: Samples undergo destructive testing using a universal testing machine to verify the 103 MPa (15 ksi) yield strength for H14 and 152 MPa (22 ksi) for H18. Automated systems record the stress-strain curves, verifying that elongation percentages meet the 9% minimum requirement.
Dimensional Tolerance Measurement: Automated laser micrometers scan the plates to confirm thickness tolerances remain within ±0.05mm for thin gauges. Width and length measurements are verified to ensure maximum deviations do not exceed +2.0mm, allowing seamless physical integration into automated robotic welding cells on assembly lines.
Surface Defect Inspection: High-resolution optical scanners evaluate both sides of the cold-rolled plates for micro-cracks, inclusions, or rolling marks. Products intended for exterior bus panels undergo specific gloss and roughness evaluations, ensuring flawless surface adhesion for subsequent fluorocarbon spraying or paint spraying chemical treatments.
