Shear Strength – 4043 has lower shear strength than that of 5356 (see Fig 1). This may be of consideration when calculating the size of fillet welds.
What is the difference between ER5356 and ER4043 welding wire?
ER4043 can be used in working environments with operating temperatures exceeding 150°F (66°C). In contrast, ER5356 filler metal is not suitable for prolonged high temperature environments due to its 5% magnesium content.
What can I weld with 4043 wire?
For 6xxx series base metals, and 5xxx series base metals containing up to 2.5% (nominal) Magnesium use either 4043/4943 or 5356. For 5xxx series base metals containing more than 2.5% (nominal) Magnesium use 5356 filler metal and do not use 4043/4943 filler metal.

The Lowdown on 4043 and 5356
First things first, both 4043 and 5356 are aluminum-silicon alloys. That means they’re primarily aluminum, but they have a bit of silicon mixed in, which is like adding a secret ingredient to give them special powers.
4043
4043 is like the “all-rounder” of aluminum welding wire. It’s got a great balance of strength, corrosion resistance, and weldability. Think of it as the friendly neighbor you can always rely on. This wire is super versatile and used for a ton of different applications.
5356
5356 is known for being tougher and more resistant to cracking. This is because it has a higher silicon content than 4043. Imagine it as the strong, silent type – it might not be as flashy, but it’s got serious staying power. It’s often used in situations where you need welds to hold up under a lot of stress.
What’s the Difference?
The main difference between these two is their silicon content. 4043 is typically around 5% silicon, while 5356 can have as much as 10%. That higher silicon content in 5356 makes it better for welding thicker aluminum, especially in applications where there’s a lot of stress or vibration.
Picking the Right Wire for the Job
So, how do you know which one to use?
If you’re welding thin aluminum, 4043 is probably your best bet. It’s easier to control and gives you a smoother weld bead.
If you’re welding thick aluminum or working with something that needs to be really strong, 5356 is your go-to.
But remember, there’s more to it than just the thickness of the aluminum. You also need to think about:
The type of aluminum you’re welding (some types are more prone to cracking)
The environment the weld will be exposed to (corrosion, heat, etc.)
The desired weld strength
Important Points to Keep in Mind
Here are a few things to remember when using 4043 or 5356:
Cleanliness is key. Aluminum is a finicky metal. Make sure your workpiece and welding wire are clean and free of any oils, grease, or other contaminants. Otherwise, you’ll end up with a weak, porous weld.
Preheating is sometimes necessary. If you’re welding thick aluminum, preheating it can help prevent cracking and ensure a good weld.
Choose the right welding process. Both 4043 and 5356 can be used with a few different welding processes, like Gas Metal Arc Welding (GMAW), Gas Tungsten Arc Welding (GTAW), and Flux-Cored Arc Welding (FCAW). The best process will depend on the thickness of the aluminum, the type of application, and your personal preferences.
Proper shielding is essential. You need to shield your weld from the atmosphere to prevent oxidation. This is done with a shielding gas, like argon or helium.
Post-weld cleaning is important. Once you’re done welding, you’ll need to clean the weld area to remove any slag or spatter. This will give you a nice, finished look and help prevent corrosion.
Common Applications
4043 and 5356 are used in a wide range of applications, including:
Automotive – think car bodies, wheels, and engine parts
Aerospace – where lightweight and high strength are crucial
Marine – for boat hulls and other parts exposed to harsh environments
Construction – from aluminum siding to window frames
Manufacturing – a huge variety of products, like appliances and machinery
FAQs
Here are some frequently asked questions about 4043 and 5356 aluminum welding wire:
Q: Can I use 4043 wire on thick aluminum?
A: While you technically can, it’s not ideal. 4043 tends to crack when used on thick aluminum. 5356 is a better choice for thicker materials.
Q: Which wire is better for welding aluminum to steel?
A: You can’t directly weld aluminum to steel using 4043 or 5356. You’ll need to use a special filler metal specifically designed for this purpose.
Q: What is the difference between 4043 and 5356 in terms of strength?
A:5356 is generally stronger than 4043 because of its higher silicon content. This added strength makes it a better choice for applications where high-stress welds are required.
Q: What kind of shielding gas should I use with 4043 and 5356?
A:Argon is the most common shielding gas for welding aluminum with both 4043 and 5356. Helium can also be used, but it’s more expensive and less commonly used.
Q: Can I use 4043 or 5356 for brazing aluminum?
A: No, these wires are designed for welding, not brazing. Brazing uses a different type of filler metal with a lower melting point.
Q: What are the advantages and disadvantages of using 4043 and 5356?
A:
4043:
Advantages: Versatile, easy to use, good for thin aluminum, good corrosion resistance
Disadvantages: Can crack on thicker aluminum, lower strength than 5356
5356:
Advantages: High strength, good for thick aluminum, resistant to cracking
Disadvantages: More difficult to control, more expensive than 4043
Q: Is it possible to weld aluminum to stainless steel?
A: Yes, you can weld aluminum to stainless steel, but it requires special filler metal and a skilled welder to ensure a strong and reliable bond.
Q: What is the typical size of aluminum welding wire?
A: Aluminum welding wire comes in various diameters, but common sizes are .035″, .045″, and 1/16″. The size you need will depend on the thickness of the aluminum you are welding and the welding process you are using.
Q: Can I use 4043 or 5356 on galvanized steel?
A: It’s not recommended to directly weld to galvanized steel with 4043 or 5356. The zinc coating on galvanized steel can create harmful fumes and affect the weld’s quality. It’s best to remove the zinc coating before welding.
Q: How do I store aluminum welding wire properly?
A: Store your aluminum welding wire in a cool, dry place away from direct sunlight and moisture. You should also avoid storing it near corrosive substances.
Q: How do I know if I’m using the right welding wire?
A: Check the wire’s AWS classification or the ER number on the spool. This will tell you exactly what the wire is made of and what it’s intended for.
Conclusion
4043 and 5356 are both excellent choices for aluminum welding, each with its strengths and weaknesses. Knowing which one to use for a specific project is crucial to achieving strong, reliable welds. By understanding the differences between these two wires, you can confidently select the right one for your next welding project.
