Pure Copper 110 Plate — Heavy Thick Copper Plate Cut to Size

Pure copper 110 plate — also called thick copper plate, heavy copper plate, or solid copper plate stock — is flat-rolled 99.9% pure copper 110 in the rigid, heavy-gauge range that keeps its shape and carries heavy current or thermal load. Where thin sheet bends by hand, copper plate is engineered for structural, electrical, and industrial duty: busbar plates and collector plates, electrode and anode plates, heat spreaders and cold plates, machine components, heavy connectors, and thick washers and gaskets. It is supplied in millimeters and inches and cut to the exact length, width, or blank your drawing requires across the United States.

Heavy copper plate is the starting material for machined and milled copper parts, waterjet and laser-cut blanks, high-current busbars, and furnace, plating, and welding equipment. Standard plate sizes and custom-cut pieces are both available; thinner material is supplied as sheet, and very thin flat material as foil.

What Is Pure Copper 110 Plate?

Pure copper 110 is commercial-grade 99.9% pure copper valued for high electrical and thermal conductivity, natural corrosion resistance, and a solid, dense structure suitable for heavy machining and connection. In plate form it is a flat-rolled product in the heavy range, beginning around 6 mm (1/4 inch) and extending through the thickest standard gauges. Thick copper plate is stiff enough to drill, mill, tap, and bolt without distortion, and its mass gives it the current capacity and thermal storage needed by power and process equipment. US buyers search this material as “copper plate,” “thick copper plate,” “heavy copper plate,” “solid copper plate,” and “copper plate cut to size.”

Thickness Range and Sizes

Plate covers heavy gauges from 6 mm to 50 mm. Select thickness as the product variant, then specify the length and width or blank. All thicknesses are shown in millimeters and approximate inch equivalents.

Thinner, formable material is supplied as pure copper 110 sheet; very thin flat material is supplied as copper foil. Narrow rectangular sections are supplied as flat bar in the sheet and plate collection.

Key Properties of Pure Copper 110 Plate

Why Choose Heavy Copper Plate

• High-current busbars — thick plate is milled and drilled into collector, riser, and distribution plates in substations and equipment.
• Electrode and anode stock — heavy plate feeds welding, resistance, furnace, plating, and electrolytic equipment.
• Thermal and cold plates — the dense copper section spreads and transfers heat in power electronics and process machinery.
• Machined structural parts — plate is the blank for heavy connectors, brackets, holders, molds, and custom copper components.
• Ready-cut blanks — waterjet, laser, or sawn plate blanks arrive ready for final machining, saving shop time.
• Metric and inch projects — thicknesses and dimensions match both metric drawings and US fractional-inch builds.

How to Order Copper Plate

Common Applications

Industries That Use Thick Copper Plate

• Power & electrical engineering — substation busbars, switchgear plates, rectifiers, and heavy connections.
• Welding, furnace & metallurgy — electrode, resistance, smelting, and induction equipment plates and blocks.
• Electroplating & surface treatment — anode and cathode plates, process rails, and tank hardware.
• Power electronics & thermal management — heat spreaders, cold plates, and high-current thermal components.
• Heavy machinery & manufacturing — machined plates, brackets, holders, and custom conductive parts.
• Marine, chemical & offshore — corrosion-resistant plates and process hardware in demanding environments.

Working & Fabrication Notes

Pure copper 110 plate cuts with industrial saws, waterjet, or laser and is well suited to CNC milling, drilling, tapping, and facing. Heavy sections need sharp carbide tooling and appropriate speeds and feeds for clean cuts, and the solid plate bolts and clamps firmly for machining. Joints are made by bolting, brazing, or welding; the flat faces give large contact areas for bolted high-current connections. The natural mill surface can be left bare for industrial use, polished for visible components, or allowed to develop a stable patina in outdoor or chemical environments.

Plate vs Sheet, Flat Bar, and Foil

• Plate is the heavy, rigid range from about 6 mm upward for busbars, electrodes, thermal plates, and machined parts.
• Sheet is the thin, formable range for panels, flashing, shims, shielding, and craft work.
• Flat bar is a narrow solid rectangular section supplied in straight lengths rather than as wide plate.
• Foil is the thinnest flat-rolled material for wrapping, shielding, and fine electronics work.

Custom Cut Sizes, Blanks & Components

Pure copper 110 plate is supplied in standard plate sizes or cut to specified length, width, blank, or shape, in millimeters or inches. Repeated identical blanks, busbar plates, electrode pieces, washers, and near-net component shapes can be produced from the same thickness so parts arrive ready for final machining or installation. Thicknesses or dimensions outside the standard range, or parts requiring additional processing, are handled as custom orders, with handling time extended according to the difficulty and complexity of the work.
