The “8011A” designation refers to the specific alloy composition of the aluminum. In this case, it indicates that the aluminum contains primarily aluminum as the main element, with small amounts of other elements such as iron, silicon, and manganese. The “A” suffix typically denotes a slight modification or variation in the alloy composition.
The “-H14” designation refers to the temper or hardness of the aluminum. In this case, “H14” represents a strain-hardened and partially annealed condition. It means that the aluminum has undergone a process of cold working (strain hardening) to increase its strength, followed by partial annealing to reduce internal stresses and improve formability.
Отпуск Н14 характеризуется умеренной прочностью и хорошей формуемостью. Он обычно используется в тех случаях, когда требуется умеренная прочность и отличная обрабатываемость, например, при изготовлении листового металла, автомобильных панелях и общих структурных компонентах.
