This week's snapshot covers 5083 H116 marine-grade aluminum plate. The ingot anchor uses live SMM (Shanghai Metals Market) East-China A00 pricing; the finished-plate figure is an indicative SMM-benchmarked range - confirm the firm quote with GNEE sales. We benchmark to SMM (Shanghai Metals Market).
Market Pulse - Week of October 20, 2026
The SMM East-China A00 ingot print came in at RMB 23,530/ton on Oct 20, down RMB 120/ton from the prior session (RMB 23,650). On the surface that looks softer, but the underlying structure is tight:
Social inventory 607,000 tons, down 29,000 tons week-on-week - the fastest destocking pace in years, pushing spot toward historic lows.
Spot premium near +290 yuan/t over the front contract - high and holding, which keeps finished-plate offers firm even as the ingot ticks down.
Marine and offshore demand for 5083 H116 plate stays steady; class-society-certified material carries a persistent premium over commodity tempers.
Ingot anchor source: SMM / East-China A00, Oct 20 2026. Direction read for H116 plate: flat-to-firm.

Four-week read on 5083 H116 aluminum plate
Day-to-day the ingot slipped RMB 120/t, but spot stayed supported by record destocking, so H116 plate offers held their floor. We read the four-week path as: a soft ingot top, a disciplined plate floor, and premiums holding on certified marine material.
What to Lock, What to Wait, What to Re-grade
Lock
Cover firm H116 requirements for Q4 marine / offshore builds now. Spot premium and tight inventory mean waiting risks a higher floor, not a lower one.
Wait
If your spec allows a softer temper (O / H111) or non-certified stock, a dip in ingot could improve the entry - but confirm the temper swap clears your design code first.
Re-grade
Where 5083-H116 is over-specified for the load case, 5083-H32 or 5052-H32 can meet the same corrosion duty at a lower premium. Re-grade only with engineering sign-off.

Frequently Asked Questions on 5083 H116 Aluminum Plate
What does the 5083 H116 temper mean for aluminum plate?
5083 is a 5xxx-series Al-Mg alloy. H116 is a strain-hardened temper developed for marine plate: it stabilizes strength after rolling without heat treatment, giving good corrosion resistance in seawater. Standard references include ASTM B209 and EN 485 / EN 573.
Is 5083 H116 aluminum plate subject to China export controls?
No. 5083 is a 5xxx-series alloy and is not on the dual-use control list, so it is exported as a standard commercial product. Only certain 7xxx and 2xxx forms - thick tubes and solid round bars above defined strength thresholds - carry dual-use conditions; H116 plate is not affected.
How is GNEE's 5083 H116 plate price benchmarked?
We benchmark to SMM (Shanghai Metals Market) ingot levels plus the marine rolling premium. The indicative finished-plate range is shown in the price snapshot; firm quotes come from GNEE sales.
What are the MOQ and lead time for 5083 H116 plate?
MOQ is flexible - both small trial orders and large-volume orders (full containers, long-term contracts) are accepted. Typical lead time is 15–30 days.
