Tynulox Copper Sheet, 2 Pcs (3.9″ Square)
The Tynulox set comprises two 3.9″ copper plates made from 99.9% pure copper. Each piece measures 0.6 mm (22 gauge) thick with a metallic luster and excellent electrical and thermal conductivity. These small sheets are suitable for jewelry accents, repairs, and craft projects requiring high conductivity and good corrosion resistance.
Tynulox Copper Sheet, 1 Pcs (7.9″ x 7.9″)
This single copper sheet from Tynulox measures 7.9″ x 7.9″ with a thickness of 0.6 mm (22 gauge) and 99.9% pure copper. It combines strong heat transfer with reliable electrical conductivity. The sheet is well-suited for larger craft pieces, jewelry backings, and DIY electrical or thermal prototype work, offering both durability and good formability.
Feelers Copper Sheet Roll, 4″ x 40″ (32 Gauge)
Feelers offers a thick 32-gauge brass-copper blend sheet roll, sized 4″ by 40″. The roll is designed for robust projects requiring good electrical and thermal conductivity, along with corrosion resistance. It’s well-suited for handicrafts, jewelry backing, or as a base material for enamel and copper restoration work.
uxcell Copper Flashing Sheet Roll, 0.02 mm
uxcell’s copper flashing sheet is a long roll designed for flexible, lightweight copper work. While the listed thickness is 0.02 mm, it provides good machinability, ease of bending, and suitability for hot and cold forming, brazing, and small-scale electrical or craft projects.
Feelers Copper Sheet Roll, 1.2″ x 40″ (32 Gauge)
This Feelers sheet roll comes in a narrow width of 1.2 inches and 40 inches long, with a 32-gauge thickness. It is described as a high-hardness, free-cutting brass sheet suitable for crafts, jewelry finishing, and electrical project applications where tight tolerances and strong material are needed.
Buying Guide — Key Purchase Considerations
- Purity and alloy: Higher purity copper (around 99.9% or more) provides better electrical and thermal conductivity, as well as a brighter finish. Confirm the copper grade when selecting sheets for electronics, jewelry, or plating work.
- Thickness and gauge: Thicker sheets offer greater durability and formability for bending, hammering, or stamping. Gauge selection affects flexibility, weight, and machining difficulty. Match thickness to project requirements to avoid warping or tearing.
- Size and format: Sheets come in various sizes, from small squares to large rolls. Consider the tool compatibility, storage, and cutting methods your project requires. Rolls can be cut to custom widths, while pre-cut sheets save time for small builds.
- Ease of fabrication: Some copper sheets are easier to cut, drill, or bend. Look for smooth surfaces, minimal edge burrs, and protective films when working with delicate projects to minimize scratches during handling.
- Durability and corrosion resistance: Copper resists corrosion under typical crafting conditions, but prolonged exposure to moisture and certain chemicals can affect finishes. For outdoor or high-humidity uses, consider protective coatings or sealants.
- Electrical and thermal performance: If the goal is conductive applications, prioritize high-purity copper and keep thickness appropriate to meet desired conduction and heat transfer rates.
- Price-to-performance balance: Thicker sheets and higher purity command higher prices. Evaluate the necessity of mass, thickness, and finish against your project’s performance needs and budget.
- Compatibility with tools and processes: Ensure your equipment supports the sheet thickness (drills, saws, grinding wheels, brazing tools, soldering irons) and that the chosen sheet is suitable for enamel or coating if applicable.
- Surface finishing: Some sheets come with protective films. Remove films carefully to avoid residue, and plan for surface treatments (polishing, patina, or coating) to achieve the final look.
These options provide a range of thicknesses and widths to fit common crafts, electronics prototyping, jewelry backing, and small-scale metalworking. When choosing, align the sheet’s thickness, size, and purity with the specific demands of your project, toolset, and storage considerations to ensure successful results.
