Copper Plate
Stellanox Steel supplies premium-quality Copper Plates that offer exceptional thermal and electrical conductivity, corrosion resistance, and dimensional stability. Available in grades like C11000 (ETP Copper), C12200 (DHP Copper), and C17200 (Beryllium Copper), our copper plates are used in electrical systems, fabrication, industrial tooling, marine equipment, and architectural projects.
We provide copper plates in a range of thicknesses, finishes, and tempers, with custom cutting and international certifications as per client specifications.
What are Copper Plates?
Copper Plates are flat, rectangular sheets of copper that are thicker than standard copper sheets, typically used for machined components, busbars, high-performance electrical conductors, and decorative structures. Due to copper’s excellent thermal stability, formability, and corrosion resistance, these plates are ideal for engineering and electrical applications requiring consistent performance and longevity.

Frequently Asked Questions
Explore our FAQs for insights on materials, customization, and delivery.
What’s the difference between copper plate and copper sheet?
Copper plates are thicker (typically >6 mm) and used for load-bearing and high-conductivity applications, while sheets are thinner and used for forming or decorative purposes.
Which grade of copper plate is best for electrical systems?
C11000 (ETP Copper) is ideal for electrical applications due to its 100% IACS conductivity.
Can copper plates be machined or welded?
Yes. Copper plates can be machined using carbide tools and welded using gas or TIG welding methods.
Are copper plates suitable for marine use?
Yes. Copper’s natural resistance to seawater and biofouling makes it an excellent material for marine systems.
