5251 qotishma alyuminiy lasan umumiy ko'rinishi

5251 alyuminiy kangal nisbatan kuchli alyuminiy lasan seriyasidir 5 seriyali alyuminiy qotishmasi mahsulotlar. Alyuminiy qotishmasi 5251 nominal o'z ichiga oladi 2.0% magniy & 0.30% marganets. Yaxshi ishlash qobiliyatiga ega, o'rtacha statik quvvat, yuqori charchoq kuchi, yaxshi payvandlash qobiliyati, va juda yaxshi korroziyaga chidamlilik, ayniqsa dengiz atmosferasida. Bundan tashqari, barcha alyuminiy qotishmalariga xos bo'lgan past zichlik va mukammal issiqlik o'tkazuvchanligiga ega. It is commonly used in sheet, plate and tube form.

Typical Applications Architecture, general sheet metal work, kichik qayiqlar.

Korroziyaga qarshilik 5251 has the same high resistance to general corrosion as other non heat treatable aluminium alloys. It also has the higher resistance to slightly alkaline conditions common to the 5000 seriyali qotishmalar. The resistance of 5251 to corrosion in marine atmospheres is excellent, exceeding that of 5005, hence the frequent use of 5251 in marine applications such as small boats and dinghies.

The corrosion resistance of aluminium alloys relies on a protective surface oxide film, which when damaged is readily repaired by the rapid reaction between aluminium and oxygen. Biroq, the high reactivity of the base metal can give rapid corrosion if the film cannot be repaired, so aluminium alloys are not suitable for use with reducing media. 5251 can be anodised to improve the corrosion resistance by thickening the protective surface film.

Since aluminium is a reactive metal, it may corrode more quickly when in electrical contact with most other metals. The prediction of galvanic corrosion is complex; please consult Austral Wright Metals for specific advice.
