Aluminum Coil Price — How a Quotation Is Built

Search results for 'aluminum coil price' promise a number. Anyone who has bought coil knows the number on the screen is not the number on the invoice, and the gap is not a trick — it is the difference between a metal price and a product price. A coil is not ingot. It is ingot that has been cast, hot rolled, cold rolled to a gauge, annealed or strain hardened to a temper, slit or levelled, inspected, packed and shipped, and each of those steps has a cost that varies with the specification. A coil quotation from a supplier like this one is assembled from those process costs, line by line — which is what makes two quotations comparable line by line instead of headline by headline.

Part one: the metal benchmark

The base of every coil price is the primary aluminium price on the reference exchange for the region — the LME for most export business priced in dollars, the SHFE for domestic Chinese business priced in yuan. The benchmark moves daily, which is why coil quotations carry validity windows: the conversion part of the price is stable, the metal part is not. When you compare two suppliers' quotations issued on different days, part of any difference is simply the benchmark's movement between the two dates. Serious comparisons restate both quotes against the same day's benchmark — or ask both suppliers to quote their conversion premium over the benchmark, which is the part that is actually theirs.

Alloy moves the benchmark leg itself. A ton of 5052 or 6061 is not priced as a ton of 1050: alloying elements and the casting route add cost, and heat-treatable and marine alloys carry higher base values than commercially pure grades. In this catalogue's terms, the price ladder starts with the 1xxx coil stock family, steps up through 3003, and rises again for 5052 and 6061 — which is why the same thickness and temper in two alloys is never the same price, and why 'aluminum coil price per ton' without an alloy named is not a price at all.

Part two: the conversion premium

Gauge is the largest single conversion variable. Rolling from hot-rolled feed to 6 mm takes fewer passes than rolling to 0.2 mm; thin coil also runs slower, yields more edge trim, and demands tighter inspection. Within this supplier's published ranges — the grade coil listings run 0.2–6.0 mm for 1050, 1100 and 3003 — expect the thin end of that range to carry a materially higher conversion premium per ton than the thick end. Width works the same way in reverse: very wide coil (the listings run to 2300 mm) uses the full mill and is efficient per ton; narrow slit widths add a slitting operation, which is why slit coil is priced as coil plus slitting, not as coil.

Temper adds its share. An annealed O coil needs an annealing cycle; a full-hard H18 coil needs controlled reduction without one; a three-quarter-hard H26 takes the H2 route — strain hardened, then partially annealed back; a stabilised 5xxx temper needs its stabilisation step. None of these dominates the price, but each is a real process cost, and quotations that ignore temper are quietly assuming the cheapest route. The temper guide on this site explains the codes; the price consequence is simpler — the temper you specify is part of what you are paying for, so specify it deliberately.

Surface and coating are conversion items with their own price logic. Mill finish is the base. Bright and mirror finishes add polishing or bright-rolling discipline; stucco embossing adds the embossing pass; color coating adds the coating line, the paint system (PE or PVDF in this catalogue) and a second handling regime — which is why coated products in this catalogue are quoted with their own minimums (the powder coated sheet listing, for example, is 300 m² by area, not by weight). A coated coil quotation should always state the coating system, the color, and which face is the show face, because those three choices are the price.

Part three: quantity, packing and freight

Minimum order is a price variable disguised as a rule. The 1050, 1060, 1100 and 3003 grade coil listings each publish 5 tons per size; the 1350 electrical strip listing publishes 2 tons; the cap closure and foil listings carry their own. Below a listing's minimum, a supplier either declines, consolidates, or prices the setup across fewer tons — all three are legitimate, and the quotation will reflect one of them. Above the minimum, unit conversion cost falls as setup spreads, which is why a 25-ton programme and a 5-ton trial of the same coil are honestly different prices per ton.

Packing is small but not free, and for export coil it is specified, not assumed: the listings publish export standard packing on wooden pallets or in wooden cases, coiled eye to sky or eye to wall, with about 0.3–2.5 tons per pallet on the 3003 listing and about 2 tons per pallet on the 5052 listing. Seaworthy packing for a long route costs more than a domestic wrap, and the difference belongs in the comparison when one quote looks surprisingly cheap.

Freight closes the number. The published terms for this supplier are FOB, CFR and CIF with Qingdao as the nearest port, payment by L/C or T/T. An FOB price and a CIF price for the same coil differ by ocean freight and insurance to your port — a large, volatile, entirely external number. Compare FOB with FOB; treat CIF as a convenience price whose freight leg you can benchmark separately. And note the documents leg: the listings publish mill test certificates and Form E / Form A / CO availability — for buyers whose customs regime rewards a certificate of origin, that is part of the price equation too.

Reading two quotations side by side

A disciplined comparison restates each quote in the same five lines: benchmark date and basis; alloy and temper exactly as specified; gauge, width and form (mother coil or slit, sheet or coil); quantity against the published minimum; and terms (FOB or CIF, packing standard, documents). Quotations that match on all five lines can be compared on the remaining difference, which is then a genuine conversion-price difference. Quotations that cannot be restated into the same five lines are not yet comparable — and the missing line, not the headline number, is what to ask about. This site deliberately publishes no coil price table: the listings it consolidates publish specifications, minimums and terms, and the price itself is the quotation's job. Send the specification through the contact page and the answer will be built the way this note describes.

One more line belongs in every comparison: validity. Because the benchmark leg moves daily, a coil quotation is a price for a decision window, not a standing offer. If a project will be ordered in tranches, say so at enquiry stage — the conversation about how later tranches are benchmarked is far easier before the first order than after it.
