Product description

Welcome to our website, where we are excited to introduce the ER4047 Aluminum MIG Welding Wire – a superior welding solution designed to elevate your welding projects to new heights. In this comprehensive article, we will delve into the key features, benefits, and technical specifications of this remarkable welding wire.
Precise Melting Range
The ER4047 Aluminum MIG Welding Wire offers a precise melting range between 1070 and 1080°F (577 - 582°C). This narrow melting range ensures that the wire melts evenly, promoting uniform and reliable welds. Whether you are working on delicate or heavy-duty welding tasks, this welding wire's consistent melting range enables you to achieve the desired results with precision and accuracy.
High Conductivity
With an impressive electrical conductivity of 41% IACS (International Annealed Copper Standard) at the annealed condition, this welding wire is an excellent choice for electrical applications. Its high conductivity allows for efficient current flow during the welding process, contributing to improved welding speed and reduced heat buildup. The result is a smooth and efficient welding experience that saves both time and energy.
Optimal Density
The ER4047 welding wire boasts a density of 2.66g/mm3, making it lightweight and easy to handle during welding operations. Its optimal density ensures that the wire feeds smoothly through your MIG welding machine, minimizing the risk of jams or interruptions. Additionally, the lightweight design of this welding wire reduces operator fatigue, enabling you to work comfortably for extended periods.
Superior Corrosion Resistance
Engineered with a B (General) rating for corrosion resistance and an A (Stress Corrosion Cracking) rating, this welding wire offers exceptional protection against various corrosive environments. Whether you are welding structures exposed to outdoor elements or corrosive substances, the ER4047 welding wire helps maintain the integrity and longevity of your welds, ensuring they stand the test of time.
Consistent Thermal Expansion Coefficient
The coefficient of thermal expansion from 20℃ to 300℃ is 20×10-6/K. This consistent thermal expansion coefficient means that the welding wire and the base metal will expand and contract at a similar rate when exposed to temperature changes during welding. As a result, your welds will remain stable and less prone to cracking or distortion due to thermal stresses.
High Heat Conductivity
With a heat conductivity ranging from 150 to 170W/m·K at 20℃, this welding wire efficiently dissipates heat during the welding process. The high heat conductivity helps to prevent overheating of the weld area, reducing the likelihood of thermal damage and ensuring the structural integrity of your welding projects.

More Information About ER4047 Aluminum Mig Welding Wire

What is ER4047 Aluminum Mig Welding Wire

ER4047 is a type of aluminum welding wire that is commonly used in MIG (metal inert gas) welding processes. It is a filler metal that is specifically designed to join aluminum alloys, and is composed of 12% silicon which gives it a lower melting point than other aluminum alloys.
The ER4047 welding wire is often used for welding heat-treatable alloys such as the 6xxx series and the cast aluminum alloys. It is also suitable for welding dissimilar aluminum alloys, as it provides good fluidity and a stable arc during welding.
ER4047 welding wire is generally used for welding applications where a high-quality finish is required, such as automotive parts, bicycle frames, and aerospace components. It is also commonly used for welding aluminum pipe and tubing in the HVAC and refrigeration industries.
It is important to note that the selection of the appropriate welding wire will depend on the specific aluminum alloy being welded and the welding application. The welding parameters such as current, voltage, and gas flow rate also play an important role in the quality of the weld. It is recommended to consult with a welding expert to ensure the appropriate welding wire and parameters are used for each specific application.

Advantages of ER4047 Aluminum Mig Welding Wire

There are several advantages of using ER4047 aluminum MIG welding wire, including:
1.Low melting point: ER4047 has a lower melting point than other aluminum alloys, making it easier to work with and reducing the risk of warping or distortion during welding.
2.Good fluidity: ER4047 has good fluidity, which means that it can flow easily into joints and create strong, reliable welds.
3.High quality finish: ER4047 produces a high-quality finish with minimal porosity, making it ideal for welding applications where appearance is important.
4.Suitable for dissimilar alloys: ER4047 is suitable for welding dissimilar aluminum alloys, which can be difficult with other types of welding wire.
5.Low sensitivity to cracking: ER4047 has a low sensitivity to cracking, which reduces the risk of weld failures and increases the strength and reliability of the joint.
Overall, ER4047 aluminum MIG welding wire is a versatile and reliable filler metal that can be used in a wide range of welding applications. Its low melting point, good fluidity, and high-quality finish make it a popular choice for welding heat-treatable alloys, cast aluminum, and dissimilar alloys.
