Let’s explore the most sought-after copper round bar types available to day and why they matter.

1. Copper C101 Round Bar

Known as oxygen-free electronic (OFE) copper, Copper C101 Round Bar boasts the highest electrical conductivity of all commercially available copper grades. This makes it the ideal choice for critical electrical and electronic applications such as busbars, electrical terminals, and vacuum systems.

Key Features:

• 99.99% pure copper
• Excellent electrical and thermal conductivity
• Exceptional ductility and malleability

Ideal for applications where high conductivity and cleanliness are crucial

Industries such as aerospace and electronics heavily rely on C101 for its purity and performance.

2. Copper C103 Round Bar

Copper C103 is another oxygen-free copper alloy with properties very similar to C101. However, C103 is refined further during the manufacturing process to enhance its corrosion resistance and formability. It is often used in sensitive electronic and thermal equipment where high conductivity and minimal impurities are essential.

Key Advantages:

• High thermal and electrical conductivity
• Suitable for high-temperature vacuum applications
• Superior corrosion resistance

C103 is preferred in precision instruments and high-purity piping systems.

3. Copper C111 Round Bar

The Copper C111 Round Bar is a free-machining copper that contains a small amount of tellurium. This addition improves machinability without significantly compromising conductivity. It's especially useful where components need to be machined into intricate shapes without losing electrical performance.

Features:

• Enhanced machinability due to tellurium content
• Good thermal and electrical conductivity
• Suitable for high-speed machining

This grade is ideal for applications like electrical connectors, switches, and fasteners.

4. Copper C109 Round Bar

Copper C109 is a high-performance copper alloy, also known as free-machining copper, typically containing sulfur to aid in its machinability. It is widely used in the fabrication of turned parts that require close tolerances and smooth finishes.

Highlights:

• Excellent machinability
• Moderate electrical conductivity
• Cost-effective for high-volume production

C109 is a great choice for components like plumbing fittings, valves, and general engineering parts.

5. Copper CC102 Round Bar

Copper CC102 Round Bars are tough pitch copper products with high electrical and thermal conductivity, commonly used in structural and conductive applications. This type is ideal for construction, architecture, and general engineering purposes.

Characteristics:

• Strong and ductile
• High corrosion resistance
• Excellent weldability and brazing ability

CC102 copper is a popular choice for industrial and infrastructure projects due to its workability and strength.

6. Cupro Nickel 70/30 Round Bar

Composed of 70% copper and 30% nickel, the Cupro Nickel 70/30 Round Bar is known for its high corrosion resistance, especially in saltwater environments. It also contains small amounts of iron and manganese to enhance its strength and resistance to erosion.

Key Benefits:

• Excellent resistance to seawater corrosion
• High strength and durability
• Good fabrication and welding properties

This grade is commonly used in marine applications, desalination plants, and offshore oil platforms.

7. Cupro Nickel 90/10 Round Bar

The Cupro Nickel 90/10 Round Bar contains 90% copper and 10% nickel, offering a perfect balance of strength, corrosion resistance, and cost-efficiency. It's often used in marine systems, condenser tubes, and heat exchangers.

Attributes:

• Outstanding corrosion resistance
• Excellent ductility and toughness
• Ideal for piping and tubing systems in harsh environments

90/10 Cupro Nickel is a preferred material in shipbuilding and heat transfer systems.
