What Is Sulfur Copper Plate？

Sulfur copper plates, specifically the C14700 alloy, offer a unique combination of properties, making them advantageous in specific applications, particularly those requiring ease of machining alongside good electrical and thermal conductivity.

Advantages of Sulfur Copper Plate

Fast processing, save cost: Easy cutting: The cutting speed of sulfur copper is 2 times faster than ordinary copper, and the tool life is extended by 50%, which directly helps you save processing time and consumable costs.

Strong conduction, stable signal: It is suitable for 5G equipment and automobile circuits, which need "high-speed data transmission", and the equipment is more stable.

Durable and resistant, long life: Not afraid of rust, good corrosion resistance, suitable for automotive sensors, industrial connectors and so on.

Smooth surface good plating: Sulfur copper has excellent cutting properties. The addition of sulfur element makes the cutting speed of sulfur copper reach more than 200m/min, the tool life is extended by 50%, and the processing efficiency is significantly improved. This efficient processing performance makes sulfur copper occupy an important position in the field of precision manufacturing.

FAQ

Q: How does copper react with sulfur?

A: The copper wire reacts readily with the hot sulfur gas (S8, S4 and S2), forming a dark grey, brittle crystalline solid of copper sulfide.

Q: What does sulphur do to copper?

A: Corrosive sulfur attack of copper or silver will form copper or silver sulfide on the surface of the metal. As the sulfur builds up and layers, metal sulfide flakes can start to fall off the surface and possibly into insulation in high stress areas where a dielectric failure can occur.

Q: What happens if you mix sulfur and copper?

A: In addition to forming copper sulfide, the interaction between sulfur and copper can also lead to the formation of other copper-sulfur compounds, such as CuSO4 and CuS2O3. These compounds are important in various industrial processes. However, the sulfur-copper interaction can have negative effects on the environment.

Q: What is copper-sulfur used for?

A: Copper sulfate, a chemical compound of copper, sulfur, and oxygen, is used in a wide variety of applications, including agriculture, industry, and even medicine. It's a versatile compound known for its fungicidal, pesticidal, and antimicrobial properties.

Q: What is the conductivity of copper sulfide?

A: Copper sulfides have exceptional electrical conductivities. In this regard, previous studies have disclosed that CuS has an electrical conductivity of ~103 S. cm-1. The conductivity of Cu2S has been reported in the range of 5 - 140 S.
