We're all familiar with the two materials copper and titanium, but do you know how they compare?
In this article we'll take a look at both of these metals in detail, to see how they stack up against one another.
We'll explore their strength, corrosion resistance, thermal properties, electrical properties and cost comparison, plus consider which applications each is best suited for.
So join us as we dive into this detailed comparison of copper vs titanium!
Overview of Copper and Titanium Properties
Comparing the two metals, copper and titanium have some distinct properties that set them apart. Copper is a soft metal, making it malleable and easy to manipulate into different shapes, while titanium is much stronger and much more resilient.
Both metals are non-magnetic, but titanium has a higher melting point than copper – around 3,000°F compared to copper's 1,984°F. Furthermore, titanium is corrosion resistant whereas copper can corrode when exposed to certain elements or chemicals. This makes it an ideal choice for applications where long-term durability is needed.
Finally, titanium is also heavier than copper with a density of 4.51 g/cm³ compared to 8.92 g/cm³ for copper. All these qualities make both metals suitable for different uses in various industries such as construction, engineering, and aerospace technology.
Strength
When it comes to strength, copper and titanium are two titans in a battle of brawn. Both metals have impressive strength properties. Copper is known for its tough malleability, while titanium is known for its resistance to corrosion.
Here's a snapshot of how these two metals stack up:
- Copper features an ultimate tensile strength of 110 MPa (megapascals) and shear modulus of 45 GPa (gigapascals).
- Titanium has an ultimate tensile strength of 690 MPa and shear modulus of 44 GPa.
- Copper has a yield strength of 80 MPa, while titanium reaches 600 MPa.
We may think that titanium is the clear winner when it comes to strength, but both materials are far more similar than we might think. While titanium possesses higher tensile and yield strengths than copper, it lacks the malleability that makes copper so useful in many applications.
This means that although titanium can be used in certain projects where extreme pressure or heat will be present, its limited malleability can restrict its use in some cases where copper could provide better flexibility and performance.
Corrosion Resistance
You want to know which metal is better when it comes to corrosion resistance? Let's compare copper and titanium and see how they stack up.
When it comes to the elements, titanium has an advantage over copper because it naturally forms a protective oxide layer that prevents corrosion. Copper, on the other hand, isn't so lucky—it can corrode quickly in some environments due to its reactivity with oxygen and water.
In terms of longevity, then, titanium is definitely the winner here. That said, there are certain conditions in which copper can be extremely resistant to corrosion—especially if you take precautions like coating it with varnish or tinning it with zinc or nickel.
So both metals have their strengths and weaknesses when it comes to corrosion resistance; ultimately, you'll need to make sure your specific environment is taken into consideration before making a decision about which metal is right for you.
Thermal Properties
We're now going to focus on the thermal properties of copper and titanium. We'll examine their thermal conductivity and thermal expansion to better understand how these materials behave at different temperatures.
Both elements have unique characteristics when it comes to heat transfer. So, let's dive into a comparison of these two materials.
Thermal conductivity
Glinting in the light, copper and titanium race against each other to conduct heat, with titanium taking a clear lead. At 400 watts per meter Kelvin, titanium's thermal conductivity is nearly four times that of copper's rate of 102 watts per meter Kelvin. It is no surprise then that titanium has become the go-to for many applications requiring strong thermal conduction such as when used for cooling systems in computers or cell phones.
The difference between these two metals can also be seen when comparing their temperature resistance rates. While copper will withstand temperatures up to 1,984 degrees Fahrenheit (1,085 Celsius), titanium has an impressive melting point of 3,034 degrees Fahrenheit (1,668 Celsius). This makes it ideal for use in high temperature environments like aircraft engines and nuclear power plants.
Additionally, its low density makes it attractive as a structural material due to its light weight but still formidable strength compared with other metals. All together these qualities make titanium the superior choice for conducting heat over copper.
- Titanium conducts heat four times better than Copper
- Titanium resists higher temperatures than Copper
- Titanium is lighter but stronger than Copper
- Titanium is preferred in power plants & computer cooling systems
Thermal expansion
When heated, copper expands at a rate of 9.0 x 10^-6 K^-1 while titanium's rate is higher at 9.6 x 10^-6 K^-1, making it the more flexible metal when temperatures rise. This means that titanium is the better choice when constructing something that needs to endure extreme temperature changes without suffering any structural damage.
It also makes titanium suitable for use in aerospace and other industries that require components to be able to expand and contract with temperature swings without cracking or breaking apart. Titanium's lower thermal conductivity also means it will stay cooler than copper even after being exposed to high heat for extended periods of time, which makes it ideal for various applications such as hot water tanks and cookware where heat transfer is a major factor.
Copper may still have its advantages in some areas due to its greater malleability and ductility compared to titanium, but overall, the superiority of titanium lies in its ability to withstand temperature changes without compromising strength or structure.
Electrical Properties
You'll be intrigued to learn how these two materials differ in terms of their electrical properties. Copper and titanium offer a range of advantages that make them both desirable materials for different applications:
- Copper offers excellent conductivity, high malleability, and is relatively inexpensive when compared to other metals.
- Titanium is highly resistant to corrosion and has a superior strength-to-weight ratio when compared with copper. It also has excellent thermal properties, which make it suitable for many industrial applications.
- Both copper and titanium have high melting points, making them ideal for use in extreme temperatures or environments where durability is key.
When it comes to electrical properties, however, copper takes the crown as its electrical conductivity dwarfs that of titanium by nearly 50%. This makes copper an ideal material for wiring and other power transmission needs where reliability is essential due to its ability to quickly dissipate heat generated by electric current flowing through it.
On the other hand, titanium's low conductivity means that it is not suited for applications such as wiring or circuit boards that require fast energy transfer at a higher rate than what can be offered by this metal alloy.
Cost Comparison

In this section, we'll compare the costs of copper and titanium so you can make an informed decision. Copper is well known for being a relatively inexpensive option compared to other metals like gold or platinum. It's also widely available and easy to work with.
Titanium, on the other hand, is more expensive than copper but still generally affordable if you shop around a bit. The price difference between these two materials will depend on your location and the type of alloy you choose. However, when comparing apples-to-apples, titanium tends to be slightly more expensive than copper overall.
