Miaka ya karibuni, kama nyenzo mpya ya ubora wa juu, aloi ya alumini inapendelewa na watumiaji zaidi na polepole inachukua nafasi ya vifaa vya jadi katika nyanja nyingi. Miongoni mwa 1-8 mfululizo wa aloi za alumini, 5 mfululizo wa aloi za magnesiamu za alumini hutumiwa sana. Kati yao, 5454 sahani ya alumini na 5182 sahani ya alumini ni bidhaa za mwakilishi. Both of them have medium strength, upinzani mzuri wa kutu, processability and weldability. But there are many differences.
The main alloy elements of 5454 sahani ya alumini na 5182 aluminum plate are magnesium, and the essential difference between them lies in the composition and content of alloy elements. The content of magnesium and manganese in 5182 is more than that of 5454, and there are some differences in performance and application.
5454 aloi ya alumini:
Silicon Ndio: ≤ 0.25
Copper Cu: ≤ 0.10
Mg: 2.4 ~ 3.0
Zinc Zn: ≤ 0.25
Mhe: 0.50 ~ 1.0
Titanium Ti: ≤ 0.20
Cr: 0.05 ~ 0.20
Fe: 0.000 ~ 0.400
Al: posho
5182 aluminum plate alloy:
Zinc Zn: ≤ 0.25
Cr: ≤ 0.10
Silicon Ndio: ≤ 0.20
Fe: 0.000 ~ 0.350
Mhe: 0.20 ~ 0.50
Mg: 4.0 ~ 5.0
Titanium Ti: ≤ 0.10
Copper Cu: ≤ 0.15
Al: posho
Not only that, they are also used for different purposes. 5454 karatasi ya alumini ya chuma is used in welded structures, vyombo vya shinikizo, offshore facilities and pipelines. 5182 sahani ya alumini, thick plate and thin plate are widely used. The thin plate is used to process can covers, automobile body panels, control panels, stiffeners, brackets and other parts.
