The photograph above is the clearest single piece of grade evidence in this catalogue: the top sheet of the stack is marked 5083/H112. The listings behind it put 5083 in four places — the marine aluminium alloy plate programme (where 5083 sits in the 5xxx group with tempers F, O, H111 and H112, at plate thicknesses of 6–300 mm, widths 500–2700 mm and lengths 1000–10000 mm), the marine grade plate listing (5052/5083/5754), the English site's precision aluminum plate page (5052 and 5083), and the oil tanker plate listing, whose alloy group is 5083/5182/5454.
5083 specifications (supplier's listings)
| Alloy | 5083 |
|---|---|
| Tempers (marine programme) | F, O, H111, H112 |
| Thickness (marine plate programme) | 6–300 mm |
| Width (marine plate programme) | 500–2700 mm |
| Length (marine plate programme) | 1000–10000 mm |
| Listings naming 5083 | Marine alloy plate; marine grade plate (5052/5083/5754); precision plate; oil tanker plate (5083/5182/5454) |
| Minimum order | 3 MT was published on the supplier's 5083 product page (single-product listing; confirm the current figure when enquiring) |
The 3 MT figure needs its context, because it departs from the 5 tons per size published on the 1050, 1060, 1100 and 3003 grade listings: it was published on the company's English-site 5083 product page as that product's minimum order quantity. The site has since been restructured and the page is no longer in the current product list, so the figure is presented here as the published history of that listing — a figure to confirm in the quotation rather than assume.
For the wider marine programme — stretched plate, the full 5xxx alloy group, and the certification position — see the marine aluminum plate page. For the tanker application of the same alloy family, the 5454 page covers the grade the tanker listing groups with 5083.
Ordering 5083 plate
5083 plate is quoted as a cut list. Send the temper (H111 or H112 for most marine fabrication), the thickness, and the piece sizes with quantities; if the plate is for a classed vessel, say so in the same message — this site does not claim classification-society certification for the plate, and the answer on that point should be in writing before tonnage is committed. The photograph at the top of this page, with its 5083/H112 stencil on the top sheet, shows how plate in this programme is identified: grade and temper marked on the material itself.
Tanker buyers should read this page together with the 5454 page: the tanker listing groups 5083 with 5182 and 5454, and the two grades are frequently quoted for the same project — 5083 where the published marine dimensions govern, 5454 where the specification names it. One enquiry covering both grades keeps the temper and size decisions consistent.
Stretched plate is worth asking about for large flat fabrications: the marine programme publishes a stretched variant at 6–70 mm, and if flatness after cutting matters to your yard, name it in the cut list.
What is the minimum order for 5083 plate?
A 3 MT minimum was published on the supplier's 5083 product page. That page has been restructured since, so confirm the current minimum in your quotation.
Which tempers is 5083 listed in?
F, O, H111 and H112 in the marine plate programme; H112 is the temper visible on the plate photograph above, and H111 is published in the same programme's listings.
Is 5083 available below 6 mm?
The marine plate programme starts at 6 mm. Thinner 5xxx material is quoted from the sheet listings — 5052 covers the sheet-to-plate span on its grade page.
