Aluminum sheet Alloy 1100 1050 O h14 h24
Aluminum alloys are celebrated for their outstanding properties, lightweight nature, and affordability. Among the myriad of options, Aluminum Alloy 1100 and 1050 sheets is know due to their corrosion resistance, formability, and improved mechanical strength.
Understanding Aluminum Alloy 1100 and 1050
What is Aluminum Alloy 1100?
Aluminum Alloy 1100 is a commercially pure aluminum with excellent corrosion resistance, high thermal and electrical conductivity, and good workability. This alloy is approximately 99 percent pure, resulting in properties that make it ideal for various applications where minimal mechanical stress is involved.
What is Aluminum Alloy 1050?
Aluminum Alloy 1050, while also a commercial-grade alloy, possesses slightly higher strength than Alloy 1100, making it another excellent option for sheet metals. Typically composed of 99.5 percent pure aluminum, Alloy 1050 offers remarkable corrosion resistance, workability, and excellent weldability.
Temper Designations: O, H14, and H24
Understanding temper designations is crucial for properly utilizing aluminum sheets. The temper indicates the material's heat treatment state and provides insight into its properties.
-
O Temper (Annealed): Temper O refers to aluminum that has been annealed to achieve maximum softness. Both alloys 1100 and 1050 in this temper are easily stretch-formed and fabricated with minimal risk of fracturing.
-
H14 Temper: H14 temper indicates that the alloy has been strain-hardened (processed to bolster its strength) and partially annealed. This temper offers enhanced strength characteristics while still maintaining reasonable ductility (approximately 50% to 99% yield strength).
-
H24 Temper: H24 indicates strain-hardened and partially annealed aluminum, resulting in a product that offers a good balance of strength and formability. This temper provides better mechanical properties than H14 while remaining ideal for roller forming applications.
