3つとも防錆用の5系アルミニウムマグネシウム合金に属します。 The differences in their core performance are determined by the magnesium content gradient, clearly distinguishing their positioning and applicable scenarios. 5052 はマグネシウム含有量が最も低く (2.2% ~ 2.8%)、最高の可塑性と深絞り成形性を提供しますが、強度も最低です。 Its tensile strength in the H32 state is approximately 230~280 MPa, making it suitable for complex-shaped, lightly stressed components such as fuel tanks and sheet metal enclosures.
5A06はマグネシウム含有量が5.8%~6.8%で、高マグネシウムの錆びにくいアルミニウムに属します。 It boasts the highest strength, with a tensile strength of 315~350 MPa in the H112 state, and offers the best weld joint performance, with a weld strength retention rate exceeding 90%.頑丈な溶接構造や高負荷の耐食用途に適しています。深絞り加工における軽度の腐食保護には 5052 を選択してください。一般的な船舶溶接用途の場合は、5083 を選択します。耐久性の高い溶接構造の場合は、5A06 を選択してください。
5083アルミニウムチューブの耐食性はどうですか? Can it be used long-term near the sea?
5083 アルミニウム チューブの耐食性は、防錆アルミニウムの中でもトップクラスにあり、これがその中心的な利点です。 Thanks to the solid solution effect of a suitable amount of magnesium, a dense and stable oxide film can spontaneously form on the alloy surface, resulting in extremely low risks of intergranular corrosion and pitting corrosion. Its resistance to seawater, salt spray, and atmospheric corrosion is far superior to 2-series and 7-series high-strength aluminum, and also significantly stronger than 6-series general-purpose structural aluminum. In marine environments near the sea, the bare material can be used stably for a long time without rapid rusting and cracking, making it suitable for coastal buildings, outdoor equipment pipelines, and other scenarios. If long-term immersion in seawater or exposure to high salt spray and severe corrosion conditions is required, the oxide film on the bare material will still slowly wear away. It is recommended to combine it with hard anodizing and anti-corrosion spraying treatments to further isolate corrosive media and extend its service life. 5083 は強酸、強アルカリ、その他の腐食性の高い媒体に対して耐性がないことに注意してください。このような場合、裸材をそのまま使用することは推奨されず、特別な防食処理が必要となります。
