1000 to 7000 series Density Of ALUMINUM bar

What is Aluminum?

Aluminum is a lightweight, corrosion-resistant structural material that can be strengthened through alloying and, dependent upon composition, further strengthened by heat treatment and/or cold working Among its advantages for specific applications are: low density, high strength-to-weight ratio, good corrosion resistance, ease of fabrication and diversity of form.
 

What is Aluminum Alloy Designation System?

A system of four-digit numerical designations is used to identify aluminum and aluminum alloys. The first digit indicates the alloy group as follows:

• Aluminum. 99.00 % and greater:1xxx

Wrought Aluminum alloys grouped by major alloying elements

• Copper: 2xxx
• Manganese: 3xxx
• Silicon: 4xxx
• Magnesium: 5xxx
• Magnesium and silicon: 6xxx
• Zinc: 7xxx
• Other element. 8xxx

The last two digits identify the aluminum alloy or indicate the aluminum purity. The second digit indicates modifications of the original alloy or impurity limits.

Cast Aluminum alloys grouped by major alloying elements

• Copper 2xx.x
• Silicon, with added copper and or magnesium. 3xx.x
• Silicon:4xx.x
• Magnesium:5xx.x
• Zinc:7xx.x
• Tin :8xx.x
• Other element:9xx.x

The second two digits identify the aluminum alloy or indicate the aluminum purity. The last digit, which is separated from the others by a decimal point, indicates the product form: that is, castings or ingot.
