Blacksmiths aren't limited to iron anymore—modern metalworkers shape everything from copper to titanium depending on the project, budget, and intended use. Understanding which metals a blacksmith can handle, their working properties, and cost implications will help you commission the right piece or find the right maker for your vision. Here's what you need to know before reaching out.
Iron and Steel: The Traditional Workhorses
Iron and steel remain the backbone of blacksmithing. Mild steel (0.1–0.3% carbon) is the most forgiving to work with, heats evenly, and is ideal for decorative items, tools, and structural pieces. High-carbon steel (0.8–1.5% carbon) holds an edge better and suits blades, springs, and functional hardware.
Expect to pay $0.50–$1.50 per pound for raw material, though finished pieces carry significant premiums based on labor and complexity. A hand-forged steel gate or railing typically runs $15–$50 per square foot depending on detail level.
Copper and Brass: Color and Conductivity
Copper works beautifully for decorative elements, weathervanes, and functional pieces that benefit from its conductive properties. It's softer than steel, making it easier to shape but less suitable for load-bearing applications. Brass (a copper-zinc alloy) offers similar aesthetics with slightly better strength.
Copper costs $2–$4 per pound in raw form. Custom copper work like planters, light fixtures, or architectural details typically range from $200–$1,500 depending on size and intricacy.
Aluminum: Lightweight but Limited
Aluminum melts at a lower temperature than iron, which means not all blacksmiths can work it using traditional forge techniques. Those equipped with the right torch setup can create lightweight decorative pieces, but aluminum doesn't hold a hammer shape as cleanly as steel.
Raw aluminum runs $0.80–$1.50 per pound, making it cheaper than copper but offering fewer aesthetic rewards for commission work. If a blacksmith offers aluminum work, ask about their specific process—it's more niche than iron or copper.
Stainless Steel: Durability with a Catch
Stainless steel resists rust, making it ideal for outdoor installations and high-moisture environments. The downside: it's harder to heat, requires more fuel, and forges less cleanly than mild steel. Not every blacksmith has the setup for stainless, so confirm capability before commissioning.
Material costs run $1.50–$3 per pound. Labor charges may be 20–30% higher than mild steel due to difficulty. A stainless steel outdoor fixture might cost $1,000–$3,000.
Titanium and Exotic Metals: Specialist Territory
Titanium and specialty alloys like Damascus steel or meteorite iron appeal to high-end custom commissions. These metals require specialized knowledge, equipment, and materials handling. Most general blacksmiths don't work with them; you're looking at specialist makers.
Costs jump dramatically: $50–$150+ per pound for raw material, plus substantial labor premiums. A titanium art piece or Damascus knife can easily exceed $2,000–$10,000+.
What to Consider When Choosing a Metal
Match the metal to the purpose. Decorative indoor pieces suit copper or mild steel. Outdoor railings or gates need rust-resistant options. Tools and blades demand high-carbon steel or stainless.
Budget for material plus labor. The metal itself is often the smaller cost. A blacksmith's time, skill, and equipment far outweigh raw material—especially for detailed work.
Ask about heat-treating and finishing. The metal you see isn't always the raw metal. Blacksmiths often oil, wax, patina, or seal their work. These finishing steps affect durability and appearance, and they add to the final price.
Request sample pieces or past work. Before commissioning in an unfamiliar metal, see how your maker handles it. Mercoly lets you compare and find trusted metalwork providers in one place, making it easier to review portfolios and get quotes from multiple blacksmiths.
Frequently Asked Questions
Q: Can blacksmiths work with stainless steel the same way they work with mild steel? No—stainless steel requires higher temperatures and more specialized equipment, and it doesn't move under the hammer as predictably. Confirm your blacksmith has stainless capability before commissioning.
Q: What's the cheapest metal to commission custom work in? Mild steel is the most affordable both in raw cost and labor time, typically resulting in finished pieces 30–50% cheaper than copper or stainless alternatives.
Q: How long does a custom metal commission usually take? Simple pieces (small tools, basic decorative items) take 2–6 weeks; complex work (multi-part gates, detailed artistic pieces) can take 2–4 months or longer depending on the blacksmith's backlog.
