5454 Aluminum Plate & Coil

The supplier's 5454 coil strip page publishes the grade's designation and chemical composition — EN AW-5454, Al Mg3Mn, with magnesium at 2.4–3.0% and manganese at 0.5–1.0% (silicon max 0.25%, iron max 0.4%, chromium 0.05–0.2%) — and a properties overview describing the alloy family's corrosion resistance and its behaviour at low and elevated temperatures. The grade page itself does not publish a thickness, width or minimum order table. The tanker listing does publish dimensions for the grade — a 5454T specification row tabled below — so tanker-form 5454 has published sizes; dimensions for other forms are confirmed per enquiry.

5454 — what the published sources state

Alloy / designation	5454 — EN AW-5454, Al Mg3Mn
Magnesium	2.4–3.0%
Manganese	0.5–1.0%
Silicon / iron	Max 0.25% / max 0.4%
Chromium	0.05–0.2%
Documented listings	5454 coil strip grade page; oil tanker plate (alloy group 5083/5182/5454); English-site 5xxx plate lists
Thickness / width / length (tanker listing, 5454T row)	4–8 mm / 1000–2400 mm / 2000–12600 mm
Tempers (tanker listing)	O, H111, H112, H32
Minimum order (tanker listing)	3 tons
Grade page size table	Not published on the 5454 grade page itself — dimensions for non-tanker forms are confirmed per enquiry

The tanker connection is the documented application: the storefront's aluminium plate for oil tanker listing is built on the 5083/5182/5454 alloy group, publishes its own specification row for 5454T (4–8 mm thick, 1000–2400 mm wide, 2000–12600 mm long, in tempers O, H111, H112 and H32) and states a 3-ton minimum order for the listing; 5454's published profile — a magnesium-manganese alloy with strong corrosion resistance — is why it sits in that group. The company's English site also includes 5454 in its 5xxx plate alloy lists. Buyers working on tanker, vessel and welded structure projects typically enquire on 5454 alongside 5083; the 5083 page carries the fuller dimensional data of the marine plate programme; 5454 is not part of that marine programme — its documented place in this catalogue is the tanker listing's alloy group and its own composition page.

If your specification already fixes the 5454 dimensions, send them: for sizes inside the tanker listing's 5454T row the quotation prices against that row; for other forms it will confirm availability, temper and minimum for your exact size.

Ordering 5454

A 5454 enquiry has to do the work the grade listing leaves open: state the form (coil strip or plate), the thickness and width or the cut sizes, the temper if your specification fixes one, and the tonnage. With those four figures, the quotation confirms the size availability and the minimum for that exact requirement — against the tanker listing's published 5454T row where your form and sizes fall inside it. If the requirement comes from a tanker or vessel specification, attach the alloy clause: 5454 is often specified alongside 5083 and 5182 in the same document, and the tanker listing in this catalogue covers exactly that alloy group.

What can be settled from the published data alone is the alloy identity: EN AW-5454, an Al-Mg3Mn alloy with 2.4–3.0% magnesium and 0.5–1.0% manganese, documented by the supplier's grade page with its full chemical composition table. If your incoming inspection checks composition, that table is the reference the material will be quoted against — request the mill test certificate with the order so the delivered figure is documented per lot.

If the project documents allow either 5083 or 5454, quote both: the published data supports a firm dimensional quotation for 5083 today, and the comparison costs nothing at enquiry stage.
