2 seriyali alyuminiy qotishmalari belong to Al+Cu alloys, unda Cu ning metall tarkibiga etadi 3%-5%. 2××× alyuminiy sanoat ilovalarida nisbatan kam uchraydi. Yuqori qattiqligi tufayli 2 seriyali alyuminiy rulonli material, u asosan aerokosmik qurilish materiallarida qo'llaniladi, samolyot kabinasi panellari kabi.
2 × × × alyuminiy qotishma rulondagi umumiy qotishma modellari 2A12, 2017, 2024, 2A11, A16 (LY16) 2A06 (LY6) 2117 2A12, 2124 va hokazo.
2 series aluminum coils have higher requirements on the hardness of the material and better quality production countries include German aluminum alloys and Korean aluminum alloys. With the further development of China’s aerospace industry, the production technology of 2 series aluminum alloys has also made great progress and is widely exported. to all over the world.
