Oxygen-Free Copper: Grades, Forms, Compositions, and Properties Due to these advantageous properties, the material finds use in a variety of industrial applications. The high purity levels of oxygen-free copper enhance the properties typical of standard copper material, such as thermal and electrical conductivity, ductility, impact strength, and machinability. The electrolytic copper refining process removes most of the oxygen contained within, resulting in a compound that consists of 99.95–99.99% copper with less than or equal to 0.0005% oxygen. Ultimately, understanding the differences between these two types of alloys will help you choose the right option for your project needs.Oxygen-free copper-also referred to as OFC, Cu-OF, Cu-OFE, and oxygen-free, high-conductivity copper (OFHC)-is formed by melting copper and combining it with carbon and carbonaceous gases. For those looking for an electrical conductor with excellent malleability, then copper alloy 101 may be the right choice, whereas those working on projects demanding precision engineering would benefit from using copper alloy 110 instead due to its superior shape retention under pressure. Conclusion:īoth copper alloys 101 and 110 offer superior strength and heat resistance, but each have unique features that make them better suited for certain projects than the other one might be. HardnessĬopper 101 is softer than Copper 110, with a hardness of 2 on the Mohs scale, while Copper 110 has a hardness of 3 on the Mohs scale. DensityĬopper 101 has a density of 8.96 g/cm3, while Copper 110 has a density of 8.85 g/cm3. Boiling pointĬopper 101 has a boiling point of 2567 degrees Celsius, while Copper 110 has a boiling point of 2835 degrees Celsius. Melting pointĬopper 101 has a melting point of 1083 degrees Celsius, while Copper 110 has a melting point of 1188 degrees Celsius. Copper 101 is made of 99.9% copper and 0.04% oxygen, while Copper 110 is made of 99.9% copper and 0.1% oxygen. Difference Between Copper 101 and Copper 110 CompositionĬopper 101 and Copper 110 both have different compositions. In addition to being used in various industrial projects, this type of copper alloy is also great for creating sculptures or jewelry due to its attractive shine when polished correctly. It also retains its shape under pressure, making it ideal for applications where precision engineering is needed. This type of alloy is particularly useful when conducting projects involving high temperatures since it is highly resistant to oxidation and corrosion caused by extreme changes in temperature or humidity levels. Copper 110Ĭopper alloy 110 comprises 99.9% pure copper combined with small amounts of manganese (0.15%) and phosphorus (0.04%). Copper alloy 101 is also very malleable, making it ideal for forming shapes and intricate designs. This type of copper is most popularly used in electrical wiring due to its excellent electrical conductivity and also because it can be easily soldered or welded into place. Copper 101Ĭopper alloy 101 is composed primarily of 99.90% pure copper with a trace amount of oxygen (.04%). Let’s break down what makes these two types of copper alloys unique. In particular, copper alloys 101 and 110 are widely used in industrial applications due to their superior strength and heat resistance. Adding other metals, such as zinc or tin, makes for a stronger and more durable alloy. Copper alloys are metal combinations that contain copper as the primary material.
