Alumiinilevypaksuus

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 (>50 mm) käytetään ensisijaisesti raskailla koneissa (paineenkestävyys, joka on suurempi tai yhtä suuri kuin 1000mPa) tai muotinvalmistus (kovuus, joka on suurempi tai yhtä suuri kuin 80 hb), ja sitä voidaan edelleen parantaa lämmönkäsittelyn avulla.
