Ketebalan lembaran aluminium

Aluminum sheet thicknesses range widely, from a few microns (μm) to several feet (ft), and can be customized. The specific choice depends on the application scenario. Ultra-thin aluminum sheet (0.001-0.1mm) is suitable for high-precision applications such as electronic components (e.g., flexible circuits), optical coatings, and thin-film solar cells. Its advantages lie in its conductivity (resistivity ≤ 2.8μΩ·cm) and corrosion resistance (salt spray test ≥ 500h). Common industrial thicknesses range from 1-50mm, and are used in automotive lightweighting (30% weight reduction), architectural curtain walls (wind pressure resistance ≥ 5kPa), and aerospace structural components (tensile strength ≥ 300MPa), balancing strength and processability. Ultra-thick aluminum sheet (>50mm) terutamanya digunakan dalam jentera berat (rintangan tekanan lebih besar daripada atau sama dengan 1000mpa) atau pembuatan acuan (kekerasan lebih besar daripada atau sama dengan 80HB), dan boleh dipertingkatkan lagi melalui rawatan haba.
