Note:
- The values provided are approximate and may vary depending on specific manufacturing processes and conditions.
- Tensile strength is the maximum stress a material can withstand while being stretched or pulled before necking or fracture occurs.
- Yield strength is the stress at which a material begins to deform plastically without undergoing significant permanent deformation.
- Elongation is the percentage increase in length of a material when subjected to tensile loading before fracture occurs.
- Hardness (Brinell) is a measure of a material’s resistance to indentation or abrasion.
These mechanical properties give an overview of how 1100 aluminum strip behaves under different temper conditions, ranging from the soft and ductile annealed state (O temper) to the stronger but less formable strain-hardened conditions (H12, H14, H16, H18). These properties are crucial considerations in determining the suitability of 1100 aluminum strip for various applications in industries such as electrical, automotive, construction, and packaging.
