Copper Plate
Premium-grade copper plates with outstanding electrical and thermal conductivity, resistance to corrosion, and dimensional stability are available from Stellanox Steel. Our copper plates, which come in grades like C11000 (ETP Copper), C12200 (DHP Copper), and C17200 (Beryllium Copper), are utilised in architectural projects, industrial tools, electrical systems, fabrication, and maritime equipment.
In accordance with customer requirements, we offer copper plates in a variety of thicknesses, coatings, and tempers, along with custom cutting and international certifications.
What are Copper Plates?
Usually used for machined parts, busbars, high-performance electrical conductors, and ornamental constructions, copper plates are flat, rectangular sheets of copper that are thicker than regular copper sheets. These plates are perfect for technical and electrical applications needing reliable performance and durability because of copper’s exceptional thermal stability, formability, and resistance to corrosion.
