Aluminum Products

Aluminum is a popular metal due to a variety of attractive features that make it suitable for a range of applications. In addition to an unbeatable strength-to-weight ratio when compared to other metals (Aluminum weighs approximately 1/3 the weight of iron, steel, copper or brass), aluminum is also corrosion resistant and non-combustible. The reflective nature make aluminum a good choice for lighting fixtures. In addition, aluminum is non-toxic so it is often used in making food processing equipment. It is virtually maintenance-free and it's ability to conduct electricity is similar to copper.

Applications where aluminum is often used include transportation, equipment manufacturing, electrical, construction, and machinery manufacturing.

Alloy Designation System

A system for designating wrought aluminum and wrought aluminum alloys established by the Aluminum Association. Specific limits for chemical compositions to which conformance is required are provided by applicable product standards.

Wrought Aluminum and Aluminum Alloy

Designation System

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

Aluminum, 99.00% minimum and greater ......1XXX

Aluminum alloys grouped by major alloying elements:

Copper (Cu) .............................................................2XXX

Manganese (Mn) ...................................................3XXX

Silicon (Si) ................................................................4XXX

Magnesium (Mg) ...................................................5XXX

Magnesium and Silicon (Mg and Si) .................6XXX

Zinc (Zn) ..................................................................7XXX
