3105 h14 aluminum sheet plate
3105-H14 aluminum is 3105 aluminum in the H14 temper, with strength approximately between annealed (O) and full-hard (H18) states.
3105-H14 is primarily strengthened by manganese (Mn) and magnesium (Mg), and is widely used in applications requiring moderate strength, excellent formability, and corrosion resistance.
3105 H14 aluminum is an aluminum-manganese alloy. Its temper (H14) is achieved through work hardening and partial annealing processes, combining a certain level of strength and hardness while maintaining good workability.
3105 H14 is a strain-hardened, non-heat-treatable aluminum alloy in the 3000 series. It has been optimized to offer moderate strength, excellent formability, and corrosion resistance. Its chemical composition is mainly aluminum, with manganese and magnesium as strengthening elements, along with small amounts of silicon, iron, copper, zinc, titanium, and chromium. These characteristics make 3105-H14 particularly suitable for use in building facades, roofing, signage, and other applications requiring painted or coated sheets.
What does H14 mean in aluminum?
The H14 temper refers to aluminum alloy that has undergone a certain degree of cold working (strain hardening). In this state, the hardness and strength of the aluminum alloy are improved compared to the fully annealed state (O), but still lower than the full-hard state (H18). Aluminum alloys in the H14 temper typically have good strength and moderate ductility, making them suitable for applications that require certain strength but not extreme hardness.
What is 3105-H14?
3105-H14 aluminum is a heat-treated state of 3105 aluminum alloy, where "H14" indicates that the metal has undergone strain hardening. In this state, the aluminum alloy's hardness is increased through cold working, thereby enhancing its strength and rigidity.
