Copper Plate

Pure Copper and Copper Alloy Plate Supplier

High quality copper plates available in various grades, thicknesses and finishes for electrical, mechanical, heat exchanger and industrial applications.

What is Copper Plate?

Copper plate is a flat rolled copper product manufactured through hot rolling, cold rolling and finishing processes. It combines excellent electrical conductivity, thermal conductivity, corrosion resistance and good machinability.

According to different application requirements, copper plates are available in pure copper grades such as C10100, C10200 and C11000, as well as copper alloy grades including brass and bronze.

Copper plates are widely used in electrical equipment, transformers, heat exchangers, mechanical components, marine equipment and industrial fabrication.

Common Grades of Copper Plate

Different copper grades provide different combinations of conductivity, strength, corrosion resistance and processing performance.

Grade Material Type Main Characteristics
C10100 Oxygen Free Copper Highest purity, excellent conductivity and reliability
C10200 Oxygen Free Copper Low oxygen content and high electrical performance
C11000 Electrolytic Copper Excellent conductivity and widely used industrial copper
C26000 Brass Good strength and excellent machinability
C51000 Tin Bronze Good wear resistance and corrosion resistance

Manufacturing Process of Copper Plate

Copper plates are manufactured through controlled production processes to ensure stable chemical composition, mechanical properties and dimensional accuracy.

  1. Copper melting and casting to produce copper billets
  2. Hot rolling to achieve required thickness reduction
  3. Cold rolling to improve surface quality and dimensional accuracy
  4. Heat treatment to control hardness and mechanical properties
  5. Cutting, finishing and final quality inspection
