4047aluminum

 

4047 aluminum is a high-purity aluminum alloy containing silicon, with a silicon content ranging from 4.8% to 5.3%. It is an aluminum alloy that can provide high-quality aluminum materials for numerous applications. This article will introduce the standards, chemical composition ranges, mechanical properties, applications, temper, advantages, disadvantages, forms, and comparisons of various national grades of 4047 aluminum in detail.

 

Standards

4047 aluminum alloy follows ASTM B209, JIS H4000, and EN 573-3 standards, which specify the chemical, mechanical, physical, and heat treatment properties of aluminum alloy sheets and coils to meet the requirements of specific applications.

 

Chemical Composition Ranges

The chemical composition range of 4047 aluminum alloy is as follows: silicon (Si) content between 4.8% and 5.3%, copper (Cu) content not exceeding 0.30%, manganese (Mn) content not exceeding 0.30%, iron (Fe) content not exceeding 0.80%, chromium (Cr) content not exceeding 0.10%, titanium (Ti) content not exceeding 0.05%, zinc (Zn) content not exceeding 0.10%, magnesium (Mg) content not exceeding 0.05%, lead (Pb) content not exceeding 0.05%, silver (Ag) content not exceeding 0.05%, and the remaining is aluminum (Al).

 

Mechanical Properties

The mechanical properties of 4047 aluminum alloy are as follows: yield strength ranging from 60 to 70 MPa, tensile strength ranging from 150 to 170 MPa, and elongation of 20-25%.

 

Applications

Due to its excellent performance in both micro and macro structure, 4047 aluminum alloy is suitable for the following applications:

1. Electronics: 4047 aluminum alloy is widely used in electronic circuit boards, connectors, coils, and connectors, as well as packaging materials for electronic devices.

 

2. Heat conduction: 4047 aluminum alloy can also be used to make heat-conducting devices such as automotive engine sleeves and heat exchangers, with better thermal conductivity than other alloys.

 

3. Welding: 4047 aluminum alloy performs exceptionally well in welding and brazing applications and is suitable for high-temperature environments.

 

4. Automotive: 4047 aluminum alloy can also be used to manufacture automotive heat exchanger pipelines and other components.

 

Temper

The common temper for 4047 aluminum alloy includes O, H14, H24, H18, H16, and H12.

 

Advantages

4047 aluminum alloy has excellent fluidity, corrosion resistance, and ideal electrical performance, making it widely used in many electronic components and circuits. Its silicon content increases its performance in high-temperature environments and improves its flowability, especially in high-temperature (about 800 ℃) welding applications. Additionally, 4047 aluminum alloy is easy to process and cast and has robust oxidation and corrosion resistance.

 

Disadvantages

The strength of 4047 aluminum alloy is slightly lower than that of other standard aluminum alloys, so it may not be suitable for some specific applications. Moreover, its surface quality is poorer than that of some other aluminum alloys.

 

Most Common Forms

The most common forms of 4047 aluminum alloy are sheets and coils. It can also be sold as bulk materials and welding materials.

 

National Grade Comparisons

The international grades of 4047 aluminum alloy are ASTM B209 and JIS H4000, while its national grade in the US is UNS A94047. In the European aluminum alloy unlisted series, this alloy belongs to the unnamed aluminum-silicon alloy.

 

Conclusion

In summary, 4047 aluminum alloy is an aluminum alloy widely used in electronic, heat conduction, welding, and automotive applications. Its silicon content increases its high-temperature resistance performance and flowability, is easy to process and cast, and has excellent oxidation and corrosion resistance. However, it should be noted that the strength of 4047 aluminum alloy is slightly lower than that of similar aluminum alloys, so the correct standard and temper should be selected to adapt to different application scenarios.
