Copper flat sheet used in industrial electrical roofing and fabrication applications

Copper Flat Sheet

Copper flat sheet is a versatile and widely used material across industries such as electrical, construction, roofing, automotive, marine, and industrial fabrication. Known for its excellent conductivity, corrosion resistance, and formability, copper flat sheet plays a critical role in both functional and decorative applications.

Manufactured through advanced rolling processes, copper flat sheet offers uniform thickness, smooth surface finish, and superior mechanical properties, making it ideal for precision engineering and industrial use.

What is Copper Flat Sheet?

Copper flat sheet refers to a flat-rolled copper product with a rectangular cross-section and uniform thickness. It is produced by hot rolling followed by cold rolling processes to achieve the desired dimensions and surface finish.

These sheets are available in various thicknesses, widths, and tempers, depending on the application requirements.

Key Properties of Copper Flat Sheet

  • Excellent electrical conductivity
  • High thermal conductivity
  • Superior corrosion resistance
  • Good formability and ductility
  • Antimicrobial properties
  • Attractive appearance for architectural use

Copper Grades Used

Copper flat sheet is typically manufactured using high-purity copper grades:

  • C11000 – Electrolytic tough pitch (ETP) copper
  • C12200 – Phosphorus-deoxidized copper (DHP)
  • C10100 – Oxygen-free copper (OFHC)

Each grade is selected based on conductivity, strength, and application requirements.

Applicable Standards

Copper flat sheet is produced in compliance with international standards:

  • ASTM B152 – Copper sheet, strip and plate
  • EN 1652 – Copper and copper alloys sheet and plate
  • IS standards for copper flat products

These standards ensure consistent quality and performance.
