Hard Drawn vs Annealed Copper – What’s the Difference

Hard Drawn vs Annealed Copper

Copper is an excellent material for many applications, from plumbing pipes to electrical wiring. But two main types of copper are used in these applications – hard-drawn copper and annealed copper. What’s the difference between these two? Let’s explore the differences between these two copper varieties and how they can be used effectively.



Hard Drawn Copper

Hard-drawn copper is created through a special process called cold drawing, which involves stretching out the copper at room temperature to create wire or tubing of a desired size. This process creates a much more robust product that’s less likely to break or wear over time due to its increased tensile strength. Hard-drawn copper also has better electrical conductivity than annealed copper, making it perfect for electrical wiring applications. Hard-drawn copper is a type of copper drawn through a die to achieve a specific shape and size. This type of copper is typically used in applications where high levels of strength and durability are required, such as in electrical wiring.

Annealed Copper

Annealed copper is created by heating the raw material until it becomes malleable, then slowly cooling it down to retain its softness and flexibility. This type of copper is much more ductile than hard-drawn copper, which can be bent or molded into almost any shape without breaking or damaging the material itself. It’s also less likely to rust over time because of its increased resistance to wear and tear. Annealed copper is often used for plumbing pipes because of its ability to bend easily around corners without breaking or kinking up the pipe. Annealed copper is a type of copper that has been heated and then cooled to relieve stress and improve ductility. This type of copper is typically used in applications where flexibility and malleability are required, such as plumbing applications.

Difference Between Hard Drawn and Annealed Copper


The main difference between hard-drawn and annealed copper is their respective properties. Hard-drawn copper is stronger and more durable than annealed copper, while annealed copper is more flexible and malleable.


The different properties of hard-drawn and annealed copper also make them suitable for different applications. Hard-drawn copper is typically used in electrical wiring, while annealed copper is often used in plumbing applications.


Another difference between hard-drawn and annealed copper is their cost. Hard-drawn copper is typically more expensive than annealed copper due to the additional processing required to achieve its desired properties.




Hard-drawn and annealed coppers have unique advantages and disadvantages that make them better suited for certain applications than others. For example, hard-drawn copper is ideal for electrical wiring because of its increased strength. In contrast, annealed coppers are great for plumbing projects due to their increased ductility and corrosion resistance. To get the most benefit from either type of copper, it’s essential to understand your project requirements before selecting which type to use!
