AKA-1 T1 Aluminium is a high-strength, heat-treatable aluminum alloy from the Al-Cu-Mg family, engineered for demanding structural and mechanical applications. Known for its excellent strength-to-weight ratio, good machinability, and stable performance at elevated temperatures, it is widely used in aerospace, automotive, and industrial engineering sectors. The T1 temper indicates that the alloy has been cooled from an elevated shaping temperature and naturally aged, providing balanced mechanical strength with good formability — ideal for precision components that require durability and reliability.

AKA-1 Aluminium (also referred to as AK1 or АК1) is a Russian-origin aluminum alloy, primarily composed of aluminum (Al) with controlled additions of copper (Cu), magnesium (Mg), and iron (Fe). When designated as T1 temper, it means the alloy has been cooled from an elevated temperature after shaping and naturally aged to a stable condition. This treatment gives it a balanced combination of strength, ductility, and machinability.
