What elements will effect on
aluminum alloy sheet?Have you thought about this question, if one of the elements in aluminium alloy is missing, the performance of the aluminum alloy will also have the original?The answer is not, for example,Iron is made of iron and carbon. However the volume of carbon is extremely low. It is normally lower than 0.0128%. If the volume of carbon contained is higher than that, iron will become steel.
Let us to see together.
1,copper is an important alloy metal, it has certain level of solid solution effect. In addition, it has remarkable aging effects. Aluminum plate normally contains 2.5% to 5% copper. When the volume of cooper reaches 4%-6.8%, its aging effect performs best. Therefore most hard aluminum alloy has that range of volume of cooper.
2,adding of Silicon can strengthen the aluminum alloy.
3,Zinc only gives limited contribution to the strength of aluminum alloy.
4,Fe and Si are regular impurity metallic elements. They remarkably affect the property of aluminum alloy. FeC13 is the state of their existence. When the volume of Si is more than Fe, they formβ-FeSiAl3. Otherwise, they formα-Fe2SiAl8.. if the volume of Fe is excessively high, the metal will become brittle.
5,Chrome exists in aluminum plates in the form of CrFe and CrMn. It hinder recrystallization process. It can enhance the alloy and improve the tenacity and reduce stress of erosion and crack.
6,Al-Ti alloy and AL-B alloy are regular
aluminum alloys. The critical volume of Ti is 0.15%. if B exists, it will lower by 001%.
