There are many types of aluminum alloys. These categories are classified by numbers and are divided into 1-8 siri aloi aluminium. These numbers are defined according to the amount of aluminum contained. Sebagai contoh, the most aluminum content is the 1 siri.
1 series stands for 1050, 1060, 1070, 1000 series aluminum plates, juga dikenali sebagai plat aluminium tulen. Antara semua siri, 1000 siri tergolong dalam siri dengan kandungan aluminium paling banyak. Kesucian boleh mencapai lebih daripada 99.00%. Oleh kerana ia tidak mengandungi elemen teknikal lain, proses pengeluarannya agak mudah dan harganya agak murah. Ia adalah siri yang paling biasa digunakan dalam industri konvensional. Kebanyakannya 1050 dan 1060 siri yang sedang dalam edaran. The 1000 plat aluminium siri menentukan kandungan aluminium minimum siri ini mengikut dua angka Arab terakhir. Sebagai contoh, dua angka Arab terakhir bagi 1050 series are 50. According to the international brand naming principle, the aluminum content must reach more than 99.5% to be qualified products. my country’s aluminum alloy technical standard (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 should reach 99.5%. For the same reason, the aluminum content of 1060 series aluminum plate must reach more than 99.6%.

2 series aluminum plate represents 2A16 (LY16) 2A06 (LY6) 2000 series aluminum plate is characterized by high hardness, of which the original content of copper is the highest, kira-kira 3-5%. 2000 series aluminum sheets belong to aviation aluminum materials, which are not often used in conventional industries. Pada masa ini, there are few manufacturers producing 2000 series aluminum sheets in my country. The quality can not be compared with foreign countries. Pada masa ini, imported aluminum sheets are mainly provided by South Korean and German manufacturers. With the development of my country’s aerospace industry, the production technology of 2000 series aluminum sheets will be further improved.
