Aluminium grades at a glance with ASTM standard specification and equivalent chart
Aluminium Alloy refers to a combination of material with aluminium to make an alloy that is corrosion resistant and is stronger. Aluminium alloys are either cast or wrought and they could be used in various industrial applications. They could be either heat treated or not, depending on the standards, grades and the types of the alloy. The Aluminum Alloy properties include good tensile strength, optimum density and lightweight, the ductility, formability and weldability of the element as well. Depending on the different grades of the material, the Aluminum Alloy composition can change dramatically. There are copper, silicon, iron, manganese, magnesium, zinc, titanium, lithium and even cadmium. The Aluminum Alloy grades are nominated with numbers. There are alloys called 1100, 1145, 1230, 1350, 1440 and so on in the 1000 series. There are also the 2000 series, 3000, 4000, 5000, 6000, 7000 and the 8000 series of this material. The medium range of the Aluminum Alloy melting point at 655 degrees Celsius makes the alloys be used in various high temperature applications. The melting point differs from alloy to alloy. There are alloys that have very high melting points which could be used in the aerospace industry in jet engine parts and in combustion components. The Aluminum Alloy series denotes the composition of the material. Each number corresponds to the components in the composition and the charts can give a comprehensive understanding of what elements are available in which quantities and in which alloy series. The Aluminum Alloy price per kg differs from supplier to supplier as there are market factors involved. The stock size, the grade and the form of the product, the transportation means, the location of the Aluminum Alloy suppliers and the demand in the market all define the prices of the alloys.

ALUMINIUM TEMP 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.
