C70400 is a specific type of copper alloy known as "Copper-Nickel-Silicon," also sometimes referred to as a "Copper Alloy UNS C70400." This alloy is primarily composed of copper (Cu), nickel (Ni), and silicon (Si), with additional elements that may vary slightly depending on specific compositions and manufacturer specifications. Here are the typical composition ranges for C70400 copper alloy:

Features and Characteristics of C70400 Copper Wire:

Corrosion Resistance: C70400 offers excellent resistance to corrosion, particularly in seawater and other harsh environments. This property is enhanced by the alloy's composition of copper, nickel, and silicon, which form a protective oxide layer.

High Strength: It has good mechanical strength, which makes it suitable for applications where structural integrity and durability are required.

Wear Resistance: C70400 exhibits good wear resistance, making it suitable for components subjected to abrasive wear conditions.

Machinability: The alloy has good machinability, allowing it to be easily shaped, drilled, and fabricated into various components and parts.

Thermal Conductivity: While not as conductive as pure copper, C70400 still retains reasonable thermal conductivity, making it suitable for applications where heat dissipation is important.

Antimicrobial Properties: Like other copper alloys, C70400 has natural antimicrobial properties that inhibit the growth of bacteria, fungi, and other microorganisms on its surface.

Applications of C70400 Copper Wire:

Marine Applications: Used for marine hardware, heat exchangers, and seawater condenser tubes due to its excellent corrosion resistance in seawater.

Electrical and Electronic Components: Suitable for electrical connectors, terminals, and switchgear components where corrosion resistance and moderate electrical conductivity are required.

Industrial Equipment: Used in industrial valves, pumps, and fittings where corrosion resistance, strength, and wear resistance are important.

Heat Exchangers: C70400 is used in heat exchanger tubes and plates where resistance to corrosion and fouling is necessary.

Oil and Gas Industry: Utilized in equipment such as offshore platforms and pipelines where resistance to seawater corrosion and durability are critical.

Manufacturing: Used in various manufacturing processes where its combination of mechanical properties and resistance to corrosion and wear are beneficial.
