The cost of cast iron depends on whether the purchase is raw metal, cookware, pipe, or a custom casting. Buyers typically pay about $0.75-$2.50 per pound for new casting metal, while finished products can cost much more because of machining, labor, shipping, and installation.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| New cast iron stock | $0.75/lb | $1.50/lb | $2.50/lb | Bulk material; grade and order size matter |
| Cast iron cookware | $15 | $45 | $250+ | Price varies by size, brand, and finish |
| Cast iron drain pipe | $10/linear ft | $25/linear ft | $60+/linear ft | Pipe size and fittings affect price |
| Scrap cast iron | $0.08/lb | $0.15/lb | $0.25/lb | Local scrap-yard rates fluctuate |
What buyers pay for cast iron by product type
For a small amount of new cast iron stock, expect roughly $1.25-$4 per pound when purchased as cut plate, bar, or other finished stock. Larger foundry orders may bring the metal-only rate closer to $0.75-$1.50 per pound, before pattern creation, pouring, finishing, and freight. Retail products are priced by their use and construction, not simply by their weight.
A basic 10-12-inch skillet commonly costs $20-$60, while enameled cookware often runs $50-$250. Cast iron pipe material generally costs $10-$60 or more per linear foot, excluding fittings and installation. Assumptions: standard-grade material, ordinary order sizes, and typical U.S. retail or supplier pricing; specialty alloys and remote delivery cost more. The quoted price is meaningful only when the product type, grade, dimensions, and included work are clear.
How foundry, finishing, and delivery shape the quote
For custom castings, raw metal is only one part of the estimate. A foundry may charge for pattern or mold preparation, melting and pouring, cleanup, machining, inspection, and packaging. Small or one-off pieces usually cost more per pound than repeated production because setup expense is spread over fewer parts.
| Quote component | Typical range | What changes the charge | Pricing basis |
|---|---|---|---|
| Cast iron stock | $0.75-$2.50/lb | Grade, quantity, and form | Per pound |
| Pattern or mold work | $150-$2,000+ | Part complexity and reusable tooling | Per job |
| Pouring and labor | $75-$150/hour | Setup, crew, and production run | Per hour |
| Machining and finishing | $25-$200+/part | Tolerances, surface, and features | Per part |
| Delivery or freight | $25-$500+ | Weight, distance, and packaging | Per shipment |
A simple casting with little machining can stay near the lower end; a precise component with custom tooling and multiple finishing steps may exceed $10 per finished pound. Ask whether the quote covers tooling, machining, inspection, and freight rather than comparing metal rates alone.
Why weight, grade, and production volume change prices
Weight sets a useful starting point, but geometry also matters. A thick, simple plate is easier to make than a thin-walled part with narrow channels, undercuts, or tight tolerances. Small castings can have a high unit price because setup and handling are divided across fewer pieces.
Material grade is another cost driver. Common gray iron is generally less expensive than ductile iron, which is specified when added strength or toughness is required. A custom part weighing 5-10 pounds may carry substantial tooling and machining charges; ordering 100 identical pieces can reduce the per-piece setup allocation. Confirm grade, finished dimensions, tolerance, and quantity before treating two estimates as comparable.
Cast iron skillet prices by diameter and finish
For cookware, size and surface treatment give a more useful comparison than price per pound. A 6-8-inch plain skillet often costs $15-$30, a 10-12-inch standard skillet about $25-$60, and larger 13-15-inch pans roughly $45-$100. Enameled Dutch ovens commonly fall between $60 and $250, with premium designs reaching higher prices.
Pre-seasoning is usually included in new bare cookware, but decorative finishes, lids, and branded designs can raise the tag. Used pans may cost $10-$50, depending on condition and restoration needs. Compare diameter, included lid, surface condition, and warranty when judging cookware value.
Cast iron pipe costs per foot before installation
Drain, waste, and vent pipe pricing depends on diameter, wall specification, fittings, and whether the pipe is new or reclaimed. Smaller residential pipe may run about $10-$25 per linear foot, while larger diameters or specialty configurations can reach $30-$60 or more. Couplings, bends, hangers, and access requirements add to the material bill.
Replacement work can cost far more than pipe alone. Plumbers commonly charge $75-$150 per hour, and opening walls, floors, or concrete can add repair and disposal expenses. A short accessible replacement may take several hours; buried or concealed lines can require a larger project estimate. Request separate material and labor figures, plus allowances for wall or floor restoration.
Regional labor and freight differences on heavy castings
Material rates are not uniform across the country. Supplier access and freight can make remote or rural deliveries 10%-25% more expensive than comparable local purchases. In major manufacturing areas, multiple foundries and metal suppliers may improve competition, although higher wages can offset some savings.
Labor-heavy installation or machining quotes in high-cost metro areas may be 15%-35% above rates in lower-cost markets. Heavy castings also need suitable packaging and equipment; a shipment requiring a liftgate or scheduled delivery can add $50-$250 or more. Compare delivered prices rather than material-only rates when suppliers are in different regions.
When scrap cast iron is cheaper than new stock
Scrap yards may pay roughly $0.08-$0.25 per pound for clean cast iron, but the rate depends on local demand, contamination, and minimum loads. That makes scrap a low-cost option only when the material can be inspected, identified, and used without expensive cutting or rework. Scrap is usually unsuitable for a part requiring certified composition or consistent mechanical properties.
For noncritical brackets or decorative projects, reclaimed pieces can reduce material expense. For load-bearing parts, plumbing, or precision components, the savings may be outweighed by testing, machining, or replacement risk. Use reclaimed iron only when its grade and condition meet the project requirements.
How to lower a cast iron estimate without losing needed quality
For custom parts, provide a finished drawing, tolerance requirements, target quantity, and delivery location before requesting quotes. Avoid specifying tight tolerances on surfaces that do not need them, and ask whether an existing pattern or standard stock size can eliminate setup work. Combining repeat parts in one production run may lower unit charges.
For cookware, a plain seasoned skillet usually costs less than an enameled or specialty-branded model. For pipe replacement, compare repair with full replacement only after the damaged length and condition of adjoining pipe are assessed. Keep the material grade and performance requirements fixed while comparing optional finishes, tooling, and delivery charges.
