1100-O Commercially Pure Aluminum: 99.0% Minimum Al
ASTM B209 · Published: 2026-06-02 · Updated: July 2026
1100 is commercially pure aluminum (99.0% minimum Al) in the soft annealed (O) temper. It offers the highest thermal conductivity (222 W/m·K), electrical conductivity (59% IACS at O temper for EC grade), and corrosion resistance of all aluminum...
1100 ist commercially pure aluminum (99.0% minimum Al) in der soft annealed (O) temper. Es offers der highest thermal conductivity (222 W/m·K), electrical conductivity (59% IACS bei O temper für EC grade), und corrosion widerstand von alle aluminum alloys—bei der kosten von sehr niedrig mechanical strength. Used für chemical processing ausrüstung, food processing, heat exchanger fins, electrical bus conductors, nameplates, und spun hollowware wo formability und corrosion widerstand matter mehr als strength. Arbeiten-hardens slowly, enabling deep drawing und complex spinning operations ohne intermediate annealing.

Frequently Asked Questions
Was ist der difference zwischen 1100 und 1350 aluminum?
1350 (formerly EC grade) ist specifically refined für electrical conductor applications mit 99.50% minimum Al und controlled impurities zu achieve minimum 61.0% IACS conductivity. 1100 ist ein allgemein-purpose grade mit 99.0% minimum Al und slightly unter conductivity (~59% IACS) but better formability und wider availability. Für bus bars, verwenden 6101-T6 (heat-treated für strength + conductivity).
