Alloying elements of Wrought Aluminum Alloys

No Major Alloying Element

In this group, minimum aluminum content is 99%.

The second digit indicates the modification in impurity limits. If the second digit is zero, there is no special control on individual impurities.

Copper

When ______ is mixed with aluminum, it becomes more malleable and ductile. Pure aluminum is malleable and ductile but addition of ______ improves these physical properties.

Manganese

_________ is a grey-white, brittle metal which melts at 1245 degree Celsius. When _________ is mixed with aluminum, it provides a surface of highly resistant to wear and corrosion.

Silicon

Although _______, which melts at 1392 degree Celsius, is not metallic, it has properties which in alloy makes aluminum harder but not brittle.

Magnesium

The alloys alloyed with _________ possess good welding and corrosion-resistance characteristics. However, if the metal is exposed to high temperatures or excessive cold working, its susceptibility to corrosion increases.

Silicon Magnesium

If _______ and _________ are added to aluminum, they make the alloy heat treatable. Their series has medium strength with good forming and corrosion resistance properties.

Zinc

When ____ is mixed with aluminum, the resulting alloy is stiffer and more brittle than pure aluminum.
