What material are soldering iron tips made of? (2023)
The tip of the soldering iron is responsible for soldering or joining metal components. The tip transfer heat to the joint melts the solder and creates a strong and reliable soldering connection. Different materials are used in making soldering iron tip.
Copper, iron, and nickel-plated copper are the most common material used in soldering iron tips. Each material has its advantages and disadvantages. The copper tip heats up fast, but it is not recommended with lead-free solder. The iron tip is compatible with lead-free solder, but it takes time in heating up. Lastly, the tip made with nickel-plated copper tip gives the benefit of both materials, but it is expensive which make it inaccessible to hobbyist and DIYers.
In this article, we’ll explain different soldering iron tips material, and their advantages and disadvantages. Choose the tip material that is easy to handle for you.
Which material soldering iron tips are best?
Different materials are used in soldering iron tips and each one has a different application.
Soldering iron tips material
It is necessary to know about the different material that is used in a soldering iron tip, to make a good choice for yourself. Let’s discuss the materials used in the tip of the iron.
1. Copper
Copper is the most popular material used in the tip of soldering because of its thermal conductivity and affordability. Copper offers a lot of advantages, but it also has some disadvantages.
You can identify copper iron from its color as you see in the above picture.
Advantages
- Copper is known for its excellent thermal conductivity. It allows the soldering iron tip to heat up quickly and transfer heat efficiently.
- Copper tips heat up quickly and recover heat quickly after coming in contact with joints. This enhances work efficiency.
- Copper is budget-friendly, so tips made with copper make the soldering iron affordable.
- It is compatible with a wide range of soldering applications, from electronics to hobbyists.
- Copper tips are corrosion-resistant.
Disadvantages
- Copper is a soft metal, meaning copper tips can wear out more quickly than tips made from more rigid materials.
- Copper tips are also suspected of oxidation which can affect the soldering iron performance.
- It is also not compatible with acidic flux, which causes it to corrode.
- Copper tips are suitable for lead-free solder as it need a high temperature for melting.
The balance combination of thermal conductivity and cost efficiency makes the copper tips a popular choice for general-purpose soldering.
Example of some soldering iron that uses copper tips are,
2. Iron
Iron is a commonly used material for soldering iron tips due to its unique combination of properties that make it suitable for various soldering applications.
Advantages
- Iron is a robust material, so it can bare high temperatures without deforming or wearing out quickly.
- It is compatible with acidic flux and lead-free solder. Lead-free solder requires high temperature, so these iron tips provide that temperature.
- Iron tips are more corrosion-resistant than copper tips.
- Iron tips can retain heat effectively, which can be advantageous when soldering larger joints or components.
Disadvantages
- The first disadvantage is iron tips do not heat up quickly like copper. This means that these types of tips take time to reach the desired temperature.
- Iron has reasonable thermal conductivity, but it might not match the efficiency of other materials like copper.
Iron tips are a good option if you want to use lead-free solder or if you want to on high-temperature projects.
In most cases, you will see copper tips coated with iron. Copper gives fast heating while iron increases its durability.
An example of a soldering iron station that uses iron is the Hakko station (Amazon link). This station is best for beginners as it comes with a low price tag.
3. Nickel-plated copper
Nickel-plated copper soldering iron tips have gained popularity as a viable option for various soldering applications. It is a hybrid version of both copper and iron tips means it combines the benefits of both.
Advantages
- It offers a protective barrier from corrosion and erosion, which make it more durable.
- The life span of nickel-plated copper tip is more prolonged than copper and iron tip as it has excellent corrosion resistance.
- It is compatible with both lead-free solder and acidic flux.
- Nickel-plated copper offers high thermal conductivity, so it heats up quickly.
Disadvantages
- Nickel-plated copper tips are comparatively more expensive than copper and iron. This makes it inaccessible to hobbyists and DIYers.
- Nickel-plated copper offers a blend of advantages that make it the best option for many soldering applications, but it has a very high price.
Considered your budget before selecting any tip.
Copper Vs Iron soldering tip
As you see n the above both copper and iron tips has its advantage and disadvantage.
- Copper is best for fast heating while iron tips can’t heat up that fast
- Copper is easy to wear and tear while iron tips are solid and reliable for a long run
Choosing the right material
The selection of the right material tip depends upon the type of project you are working on. Copper iron tips are generally recommended because of their high thermal conductivity and budget-friendly features. It is accessible to every person who wants to do soldering.
If you want to work with high temperatures and want to use lead-free solder then iron and nickel-plated copper are the best option. But nickel-plated copper is very expensive and iron tips take time to heat up.
These all materials have their advantages and disadvantages so select the tip that best suits your situation and project requirements.
Maintenance of tips
Regardless of the tip material, tips always need proper maintenance to extend the soldering iron tip lifespan.
1. Clean the tip
With time and with different soldering application make the tip of iron become dirty, oxidized, and contaminated. This not only damages the tip with time but also makes the heat transfer to the joint difficult.
Try to clean the tip after every use with the help of a damp sponge and brass sponge to remove solder residue and oxidation.
2. Tinning the tip
Tinning the tip means applying a little solder to the tip it protects the tip from oxidation and keeps it clean. This also makes soldering easier, as a thin layer of solder a heat connection between the tip and the components of your soldering.
Tin the tip when not in use cover the tip with a thin layer of solder.
3. Use flux
Make sure you use flux while doing solder, it improves solder flow and prevents the tip from oxidation. By preventing tips, flux is extending the lifespan of the soldering iron tip.
Use the flux that is suitable for your soldering iron and also apply the right amount of flux to the tip.
4. Proper storage
It is important to store the soldering iron in a humidity-free place, as it will cause the tip to wear out and make the soldering iron of no use.
Try to store your soldering iron in a dry and clean place. The wet place may cause rust to the tip of an iron.
Conclusion
Various materials are used in making the tip of the soldering iron.
Copper, iron, and nickel-plated copper are the material that is used in the tips of iron. Copper is offer high thermal conductivity, iron can bare high temperatures and nickel-plated copper offers both thermal conductivity and can also bare working with high temperatures.
Nickel-plated copper is very expensive, so tips made from copper are generally recommended as it is inexpensive and has high thermal conductivity making it the best option for hobbyists, university students, and DIYers.
The selection of tips depends upon your project requirement means if you want iron to work with high temperatures or use lead-free solder and many others.
