The aluminum code number 1100 identifies what type of aluminum?

• A. Alloyed aluminum
• B. Heat-treatable aluminum
• C. 99 percent commercially pure aluminum
• D. Aluminum with high strength

Answer: (C)

The aluminum code number 1100 is classified as 99 percent commercially pure aluminum. This designation indicates that the alloy is composed primarily of aluminum with a very minimal amount of alloying elements. Typically, the 1100 series is known for its excellent corrosion resistance, high thermal and electrical conductivity, and good workability, making it suitable for applications where high purity is essential. The classification allows for various applications such as food processing equipment, chemical handling, and architectural designs where non-corrosive properties are beneficial. The high purity level contributes significantly to its properties, distinguishing it from other aluminum alloys that contain other elements which modify characteristics like strength or heat treatment response. Understanding these properties can help in selecting the appropriate aluminum type for specific applications where purity and corrosion resistance are more critical than strength or enhanced mechanical properties.
