Copper has long been one of the most valuable metals in the world due to its excellent electrical and thermal conductivity, corrosion resistance, and durability. Among the various copper grades available today, Copper C10300 stands out for its superior purity and performance. Known as oxygen-free copper, this grade is widely used in industries that require high conductivity, vacuum applications, and precision engineering.
If you are looking for a reliable Copper C10300 Tubes supplier, this guide will help you understand everything about the material — from its composition and properties to its industrial uses and benefits.
Copper C10300 is a high-purity, oxygen-free copper alloy that contains at least 99.95% copper. It is produced through a controlled process that eliminates oxygen and other impurities. This results in a copper tube that offers exceptional conductivity and is resistant to hydrogen embrittlement — a common issue in oxygen-bearing coppers.
C10300 is sometimes referred to as oxygen-free electronic (OFE) copper, meaning it’s ideal for applications that require precise electrical performance and minimal contamination. The absence of oxygen enhances its mechanical strength and ensures superior formability during fabrication.
| Element | Content (%) |
|---|---|
| Copper (Cu) | 99.95 min |
| Phosphorus (P) | 0.0003 max |
| Oxygen (O) | 0.001 max |
| Silver (Ag) | 0.002 – 0.007 |
This precise chemical composition makes Copper C10300 one of the purest forms of copper available on the market.
When industries choose Copper C10300 Tubes, they do so for specific advantages that make this alloy stand apart from standard copper materials.
C10300 offers one of the highest electrical conductivities among copper grades — up to 101% IACS (International Annealed Copper Standard). This property makes it perfect for electrical and electronic applications that demand efficient current flow.
Due to its high purity, C10300 efficiently transfers heat, which is crucial in applications such as heat exchangers, radiators, and cooling systems.
Copper C10300 has excellent resistance to atmospheric and industrial corrosion. It performs well in both fresh and saltwater environments, extending the life of the component.
C10300 Tubes can be easily bent, flanged, or welded without cracking. Its ductility allows it to be used in complex designs and tight installations.
Copper is naturally antimicrobial and non-magnetic, making C10300 tubes safe for use in sensitive medical and electronic systems.
Unlike oxygen-bearing coppers, C10300 is resistant to hydrogen embrittlement. This makes it reliable in high-temperature and high-vacuum environments.
The production of C10300 Copper Tubes involves a highly controlled process to maintain purity and performance standards.
Melting: Pure copper cathodes are melted under a controlled atmosphere to prevent oxygen absorption.
Casting: The molten metal is cast into billets or rods.
Extrusion: The billets are extruded into tube shapes using specialized dies.
Cold Drawing: Tubes are cold-drawn to achieve precise dimensions and improved mechanical strength.
Annealing: To enhance ductility and relieve internal stresses, tubes undergo annealing in a vacuum or inert environment.
Surface Finishing: Finally, tubes are cleaned and polished to achieve a smooth, defect-free surface.
Each step is carefully monitored to ensure the highest quality and consistency in every tube produced.
