Aluminum Alloy grades at a glance with ASTM specification and equivalent chart

Aluminium alloy refers to a combination of materials with aluminium to create a corrosion-resistant and stronger alloy. These alloys come in two main forms: cast or wrought, and find application in various industrial uses. Depending on standards, grades, and alloy types, they may or may not undergo heat treatment. The properties of aluminium alloys encompass good tensile strength, optimal density, lightweight nature, ductility, formability, and weldability. The composition of aluminium alloys can significantly change based on different grades of the material, incorporating elements like copper, silicon, iron, manganese, magnesium, zinc, titanium, lithium, and even cadmium. These alloys are categorised into series denoted by numbers, such as the 1000 series (e.g., 1100, 1145, 1230, 1350, 1440), 2000 series, 3000, 4000, 5000, 6000, 7000, and 8000 series. The medium-range melting point at 655 degrees Celsius allows these alloys to be utilised in various high-temperature applications, with melting points differing from one alloy to another. The series number in Aluminum Alloy denotes the material composition, and each number corresponds to specific components. Comprehensive charts provide insight into the quantities of elements present in each alloy series. The Aluminum Alloy price per kg varies among suppliers due to market factors, stock size, grade, product form, transportation means, supplier location, and market demand.

Aluminium Alloy Temperature Range

Now you can calculate the thermal expansion of aluminium material online using below formula
  • (µm)/(m∙K) = Thermal expansion coefficient λ
  • 23.5 µm/(m * K) : Alu. alloy 6063 Value
  • For 2700 mm long material at -20̊ C, then it will be 23.5 µm/(m * K) * 2700 mm * 50 K (from-20 Degree C to + 30 Degree C) = 3172.5 µm = 3 mm at +30 Degree C.
