About 1xxx Series Alloys
The 1xxx series alloys are comprised of aluminum 99% or higher purity. This series has excellent corrosion resistance, excellent workability, as well as high thermal and electrical conductivity. This is why the 1xxx series is commonly used for transmission, or power grid, lines that connect the national grids across countries such as the United States. Common alloy designations in this series are 1350, for electrical applications, and 1100, for food packaging trays.
Characteristics
1350 H14 is a commercially pure, very ductile in extruded condition. Excellent resistance to corrosion. Excellent electrical conductivity.
Applications
Mouldings, lightly stressed and decorative assemblies in architecture and transport, chemical, food and brewing equipment, heat exchangers.
