When it comes to selecting the right copper alloy for your project, it's important to consider the specific requirements of your application. Copper C11000 and C12200 bars are both popular choices due to their excellent electrical and thermal conductivity, corrosion resistance, and ease of fabrication. Here's a comparison of Copper C11000 bars vs. Copper C12200 bars to help you determine which is the best option for your project:
Composition
Copper C11000 bars are a high-purity copper alloy with a minimum copper content of 99.90%, while Copper C12200 bars are a brass alloy containing copper and zinc with a copper content of approximately 99.9%.
Strength
Copper C12200 bars have higher tensile strength and yield strength compared to Copper C11000 bars. This makes them more suitable for applications requiring higher mechanical strength, such as fasteners and connectors.
Corrosion Resistance
Both Copper C11000 and C12200 bars are highly resistant to corrosion. However, Copper C11000 bars offer better resistance to corrosion in seawater and marine environments due to their high copper content.
Electrical Conductivity
Copper C11000 bars have the highest electrical conductivity of all copper alloys, making them an excellent choice for electrical applications that require high conductivity.
Thermal Conductivity
Both Copper C11000 and C12200 bars have excellent thermal conductivity. However, Copper C11000 bars have slightly higher thermal conductivity than C12200 bars.
Fabrication
Both Copper C11000 and C12200 bars are easy to machine and fabricate. However, Copper C12200 bars are more easily formed due to their higher zinc content.
When comparing Copper C11000 bars vs. Copper C12200 bars, it's important to consider factors such as the required strength, corrosion resistance, electrical and thermal conductivity, and ease of fabrication for your specific application. Copper C11000 bars are an excellent choice for electrical applications that require high conductivity and resistance to marine environments, while Copper C12200 bars are better suited for applications requiring higher mechanical strength.
