We all know that 5052 aluminum plate is a combination of various elements, which will also contain some impurity elements, you may not understand the role of some of the impurity elements in 5052 aluminum plate, then 5052 aluminum plate manufacturers will give you an introduction.

1. Chromium: Chromium and manganese have similar functions, which can improve the strength of welding seams, reduce the tendency of welding thermal cracking, and improve the stress corrosion resistance, but with a slightly lower plasticity.

2. Beryllium: adding trace amount of beryllium (W (Be) = 0.0001% 0.005%) into the high magnesium alloy can reduce the crack development tendency of the ingot and improve the surface quality of the rolled sheet.

3. Add a small amount of titanium alloy grains into the high titanium alloy.

4, iron: iron, manganese and chromium can form insoluble compounds, if there are more hard brittle compounds, easy to affect the processing of cracks.In addition, iron also reduces the corrosion resistance and performance of the alloy, so we should generally control W (Fe) < 0.4%, for the choice of welding wire for material development is best to limit W (Fe) < 0.2%.

5. Silicon: Silicon is a harmful impurity (except 5A03 alloy).Silicon and magnesium form the Mg2Si phase.Due to the high content of magnesium, the solubility of Mg2Si phase in the matrix will decrease, so that not only the strengthening is less, but also the plasticity of the alloy will be reduced.

6, copper: trace amounts of copper can make the corrosion resistant material quality of these alloys worse, so w (Cu) < 0.2% should be limited, some research alloys are more restricted.
