How To Tell Grade Of Aluminum Sheet

In most cases it can be difficult to choose the correct aluminum grade for your intended application.

How to tell grade of aluminum sheet.

Cast aluminum alloys and wrought aluminum alloys. 6xxx magnesium silicon alloy. This is one of the most common kinds of aluminum especially 6061 and it anneals. Although the absolute minimum aluminum content in this group is 99 the minimum for certain grades is higher than 99 and the last two digits represent the hundredths of a per cent over 99.

7000 series 1 to 7 zinc 8000 series up to 2 5 lithium. Its major alloying elements are magnesium 1 0 and silicon 0 6. One might get a good start on structural aluminum if one could just make the major classifications in which case one might be able to use a fairly crude qualitative approach. A letter representing temper follows the first four digits to indicate if the material is supplied already work hardened h or heat treated t or annealed o at the mill.

Like with any grade it starts with the makeup of the metal. This makes it highly resistant to corrosion stress and cracking. This is common to see in sheet metal form and it s malleable stuff. Aluminum is a common metal used for both industrial and non industrial applications.

When choosing an aluminum grade consider if the following are important factors. Grade 1050 aluminium has the lowest strength of all the commercial grades of aluminium. It is most commonly available in h14 temper which in technical terms is classed as half hard. Annealing works fine for complicated and deep forming but to form simpler stuff it s unlikely that you ll need it.

Typical end use applications. In the case of unknown steel grade we can based on the physical and chemical properties of the steel with the help of simple tools to determine if it is stainless steel and what kind of stainless steel it is. Cast alloys of aluminum are those which contain 22 alloying elements by composition whereas wrought aluminum alloys contain 4. I probably won t see much of this unless somehow i get.

1050h14 is an extremely ductile grade of aluminium and therefore it is most commonly used by fabricators and sheet metal workers who will bend and form the sheet into a requested shape. If your project does not have any physical or structural demands and the aesthetics are not important then almost any aluminum grade will do the job. Use the quick reference chart at the end of this article to quickly and easily find the aluminum grade that is right for you. Observing the color of the item after picking process.

Aluminum alloys can be broadly separated into two categories. This also means the grade features good formability and weldability.
