What is Oxygen Free Copper?

Oxygen Free Copper (OFC) is a high-purity copper, boasting an impressively low oxygen content of less than 0.001%. Historically, the pursuit of purer copper dates back to the early 20th century when demand grew for better electrical conductivity. Fast forward to the modern day, and advances in refining techniques have since perfected its production.

Types of Oxygen Free Copper

C10100

C10100 is designated as OFE, or oxygen-free electronic, and achieves a minimum electrical conductivity rating of 101% IACS under annealed conditions. C10100 is recommended for applications requiring high ductility and electrical and thermal conductivity.

C10200

C10200 is 99.95% pure copper. It is an ideal choice when the material needs a strong resistance against stress corrosion cracking. It also has excellent conductivity, welding, and soldering characteristics, the same as C10100.

C11000

C11000 is also known as electrolytic tough pitch copper or ETP. Though it is 99.9% pure copper, ETP copper contains more oxygen than OFE copper, with OFE having less than 10 ppm of oxygen, whereas ETP contains a minimum of 150 ppm of oxygen. However, ETP is the most commonly used grade copper for its inherent fabrication qualities.

Benefits of Oxygen-Free Copper

High Conductivity

Oxygen-free copper's high conductivity makes it an excellent choice for applications requiring efficient electrical transmission. Its low resistance allows for better energy efficiency and reduced power loss.

Thermal Capacity

Oxygen-free copper also has excellent thermal capacity, so if you need it for projects with heat dissipation, it’s perfect. This property particularly benefits electronic devices and power systems that generate significant amounts of heat.

Excellent Fabrication Properties

Oxygen-free Copper is known for its excellent fabrication properties, including its ease of forming, welding, and machining. This makes it a versatile material used in various manufacturing processes and applications.
