Online Metals C110 Copper Sheet 6×12 18 Gauge 2 Pack

Description

Product Overview

Online Metals presents a pair of premium C110 copper sheets, each measuring 6 inches by 12 inches with an 18‑gauge (1.02 mm) thickness. Crafted from high‑purity C110 copper, these plates deliver exceptional electrical conductivity, typically exceeding 97 % of the International Annealed Copper Standard (IACS), and provide outstanding resistance to corrosion, making them ideal for both artistic and technical applications. The sheets are supplied as a convenient two‑pack, allowing hobbyists and professionals alike to experiment with larger projects or keep a spare on hand for future work. Their flat, uniform surface finishes smoothly after the annealing process, ensuring reliable performance when used for grounding, shielding, or as a substrate for electroforming. The dimensions and gauge are carefully selected to balance flexibility with strength; the copper can be bent, cut, or shaped without cracking, yet retains enough rigidity to serve as a stable base for intricate designs. Whether you are creating custom jewelry components, fabricating prototype circuitry, or producing decorative metal art, these copper sheets provide a versatile foundation that meets the demanding standards of modern makers. The copper’s natural reddish hue adds an aesthetic appeal that can be enhanced through patination or polishing, giving creators the flexibility to achieve a range of visual effects from bright, mirror‑like finishes to aged, verdigris tones. Additionally, the material’s thermal conductivity helps dissipate heat in electronic assemblies, reducing the risk of component overheating during prolonged operation. With a price point of $29.99 for the pair, these sheets represent a cost‑effective solution for small‑scale production runs and prototyping, delivering professional‑grade performance without the expense of bulk orders.

Usage

Artists and jewelry designers appreciate the fine balance of thickness and pliability offered by the 18‑gauge C110 copper sheets, which allow intricate hand‑crafted pieces to be formed with minimal effort. The 6 × 12 inch size provides ample workspace for stamping, engraving, and laser cutting, while the pure copper composition ensures that the final product retains a bright, conductive surface that can be polished to a high shine or treated with chemical patinas for a vintage look. When used as a substrate for electroforming, the sheets act as an excellent cathode, accepting metal deposits evenly across their surface and producing smooth, durable layers of nickel, silver, or additional copper. This makes them a favorite among hobbyists who create custom rings, bracelets, pendants, and ornamental components that require both aesthetic appeal and reliable electrical properties. The sheets can also be cut into smaller shapes using standard metal shears or a CNC router, enabling designers to produce repeatable components for small‑batch production or personalized gifts.
Beyond personal crafting, the copper sheets serve as a versatile medium for interior design and architectural applications. Their natural metallic sheen adds a contemporary touch when incorporated into wall panels, ceiling accents, or decorative inlays, and the material can be easily adhered to wood, drywall, or glass using conductive adhesives for functional art installations. In model making and hobbyist engineering, the sheets provide a lightweight yet sturdy substrate for constructing scale prototypes of automotive parts, aerospace components, or mechanical assemblies, where accurate dimensions and reliable conductivity are essential for testing. The 18‑gauge thickness offers enough rigidity to maintain shape under load while remaining thin enough to be folded into complex curves for aerodynamic surfaces or artistic sculptures. Additionally, the copper’s excellent thermal conductivity makes it an effective heat‑spreading layer in DIY LED lighting fixtures, helping to dissipate heat and extend the lifespan of electronic components. By combining aesthetic appeal with practical performance, these sheets enable creators to bridge the gap between form and function across a wide range of projects.

FAQ

Can the copper sheets be used for electroforming projects?

Yes, the C110 copper sheets are an excellent choice for electroforming because their high purity and uniform grain structure provide a consistent cathodic surface that promotes even metal deposition. Before starting an electroforming run, the sheets should be thoroughly cleaned with a mild alkaline solution to remove any oils or oxides, followed by a brief acid dip to activate the surface. Once prepared, the copper acts as a reliable cathode, allowing nickel, silver, or additional copper layers to build up uniformly across the entire sheet. The 18‑gauge thickness is sufficient to withstand the mechanical stresses that can occur during plating without warping, and the sheets can be cut to the exact dimensions required for the final part. After plating, the copper can be easily stripped or retained as part of the finished component, depending on the design intent. This flexibility makes the sheets suitable for creating jewelry pieces, decorative panels, and functional prototypes that benefit from the strength and conductivity of copper.

What tools are recommended for cutting and shaping the 18‑gauge copper?

Cutting and shaping 18‑gauge C110 copper can be performed with a variety of common metalworking tools, allowing both hobbyists and professionals to work efficiently. For straight cuts, a fine‑toothed hacksaw or a dedicated metal shear provides clean edges with minimal burr formation. When a more precise or intricate shape is required, a CNC router equipped with a carbide‑tipped end mill or a laser cutter can produce accurate contours and holes. Bending the sheets is straightforward using a bench vise with smooth jaws or a dedicated copper bender; the material’s low spring‑back means the bend angle can be set and held without excessive force. Soldering is best done with a rosin‑core solder and a temperature‑controlled iron set to around 350 °C, ensuring a strong joint without overheating the copper. For finishing, a deburring tool or fine sandpaper can smooth any rough edges, and a polishing cloth will restore the sheet’s natural shine if a mirror finish is desired.

How does the conductivity of C110 copper compare to other copper grades?

C110 copper is classified as a high‑purity grade that typically achieves 95‑97 % of the International Annealed Copper Standard (IACS), making it one of the most conductive commercially available copper alloys. In comparison, standard electrolytic tough pitch (ETP) copper, often labeled as C102, usually reaches around 92‑94 % IACS, while the lower‑grade C101 may fall below 90 % IACS. The higher conductivity of C110 results from its reduced impurity content, particularly lower levels of oxygen and phosphorus, which can impede electron flow. For applications that demand minimal voltage drop, such as grounding planes, high‑frequency RF components, or precision instrumentation, the extra conductivity of C110 can translate into measurable performance gains. Although the cost of C110 is modestly higher than that of standard grades, the improvement in electrical efficiency and the material’s superior corrosion resistance often justify the investment for demanding projects.

Is there a return policy if the sheets arrive damaged or do not meet specifications?

Online Metals offers a straightforward return policy that covers any shipment arriving with visible damage, dimensional inaccuracies, or conductivity values outside the guaranteed range. Customers should inspect the packaging upon receipt and document any issues with photographs, then contact the support team within 14 days to initiate a claim. The company will arrange for a prepaid return label, and once the returned items are received and verified, a full refund or replacement will be issued according to the buyer’s preference. For cases where the copper sheets meet the advertised specifications but the buyer decides they are not suitable for the intended project, a standard return is also accepted within 30 days, provided the product is in its original packaging and has not been altered. This policy ensures that purchasers can buy with confidence, knowing that quality concerns are addressed promptly and fairly.
