What thickness ranges does 8011 foil cover for different applications?
Standard thickness spans 0.006mm (pharmaceutical) to 0.2mm (industrial containers). "Double zero" foil (<0.035mm) dominates food wrapping markets. Thickness tolerance maintains ±5% for <0.02mm foils and ±3% for thicker gauges. Roll widths typically range 100-1650mm with custom slitting available. Thinner foils (0.006-0.01mm) require precision rolling mills with 0.1μm control.
How does temper designation affect 8011's mechanical properties?
O-temper (annealed) achieves 40-80MPa tensile strength with 25% elongation. H18 temper reaches 180MPa UTS but only 3% elongation. H24 temper balances 120MPa strength and 8% elongation for forming applications. Temper selection impacts pinhole frequency (<3 pinholes/m² for H18). Thermal stability varies: H24 withstands 200°C vs. H18's 150°C limit.
What surface characteristics define 8011 foil quality?
Bright side reflectivity exceeds 80% (ASTM D523-14 standard). Dull side roughness (Ra) ranges 0.4-0.8μm for adhesion. Hydrophilic coatings reduce water contact angle to <30°. Surface oil content is controlled at 2-5mg/m² (food grade). Pinhole counts are audited per ASTM B479 with <10 defects/m² for 0.02mm foil.
Which international standards certify 8011 foil performance?
EN 546-2 governs mechanical properties and tolerances. FDA 21 CFR 175.300 certifies food contact safety. ASTM B479 validates pinhole standards. ISO 209 covers chemical composition limits. RoHS/REACH compliance ensures heavy metal restrictions (Pb<0.01%).
How does 8011's thermal conductivity compare to other alloys?
201-210 W/m·K conductivity outperforms 3003 alloy (190W/m·K). Thermal expansion coefficient is 23.1×10⁻⁶/K (20-100°C range). Reflectivity of 88-92% in infrared spectrum enhances insulation. Continuous service temperature reaches 200°C (H24 temper). Heat seal initiation requires 130-150°C depending on coating.
