What is 3003 H14 Aluminum Sheet?

The alloy 3003 H14 aluminum sheet is a member of the 3000 class of alloys containing aluminum and manganese. Its primary constituents are 1.2% manganese and 98.6% aluminum. The 3003 H14 aluminum sheet has undergone strain hardening and partial annealing, yielding a material with moderate strength and acceptable formability, as indicated by the “H14” temper designation. It is frequently utilized in applications that need for a compromise between strength and formability, such as general sheet metal production, chemical equipment, and kitchen utensils.

3003 H14 Aluminum Sheet Applications

3003 H14 Perforated Aluminum Sheet

 H14 perforated aluminum sheet refers to a specific type of 3003 aluminum alloy sheet that has been processed to have perforations or holes in its surface. The “H14” temper designation indicates that the sheet has undergone strain hardening and partial annealing, providing moderate strength and good formability. Perforated aluminum sheets are commonly used in applications where airflow, visibility, or filtration is desired, such as in architectural, decorative, or industrial applications. The perforations can be in various shapes (round, square, slotted, etc.) and sizes, allowing for customization based on specific project requirements.
