Selection of Alloy Decides the Quality of Extruded Aluminum Profile

When it comes to extruded aluminium profiles, the choice of the alloy significantly impacts the final product’s quality. Aluminium extrusion is a versatile manufacturing process used in a variety of industries, and the choice of alloy has a substantial influence on the properties and applications of extruded profiles. In this article, we will examine how different types of alloys affect the quality of extruded aluminium profiles, as well as a specific alloy, alloy 1070, offered by Alumac for aluminium extrusion using an aluminium extruder.

Understanding the Significance of Aluminium Extrusion Alloys

Aluminium extrusion is a process that uses heat, pressure, and a precisely designed die to convert unprocessed aluminium billets into complex shapes and profiles. The alloy selection is crucial because it determines the mechanical properties, appearance, and even performance of the extruded aluminium profiles.

Advantage of Alumac: Alloy 1070

Alumac, a respected name in the aluminium extrusion industry, provides a variety of alloys designed for particular applications. One such alloy is 1070, which is known for its high purity and inability to be heat treated. This alloy contains a remarkable 99.70% aluminium, making it an excellent option for a variety of applications.

Aluminium Alloy 1070 Composition

For its particular composition, Alloy 1070 is highly regarded. This alloy is predominantly composed of aluminium (Al) with few impurities. Its constituent elements are as follows:

• Aluminium (Al): 99.70 percent
• Other Elements: 0.30 percent (typically consisting of iron and silicon).

The material’s high aluminium content confers superior corrosion resistance, and electrical and thermal conductivity, making it ideal for applications requiring these characteristics.

Applications of Alloy 1070 and Other Aluminium Alloys

Different alloys are designed to satisfy specific requirements and can be selected based on the properties required for a given application. Here is an overview of which alloys can yield which aluminium profile characteristics and their suitability for various industries:

• Alloy 1070 is suitable for electrical enclosures, heat sinks, and other electrical components due to its high purity and exceptional electrical conductivity.
• Alloy 6061 is widely utilised in the construction and automotive industries due to its renowned strength and weldability.
• Alloy 6063 is popular for architectural applications such as window frames and extruded shapes due to its formability and finish.
• Alloy 3003 is corrosion-resistant and suitable for marine and corrosive applications where durability is important.

The exceptional strength and corrosion resistance of alloy 5083 make it the material of choice for marine and structural applications.

In conclusion, when it comes to extruded aluminium profiles, choosing the appropriate aluminium alloy is an important choice. With its high purity and inability to be heat treated, alloy 1070 from Alumac exemplifies the significance of alloy selection. Understanding the specific composition and properties of various alloys can assist industries in selecting the most appropriate alloy for their particular applications. Whether for electrical components, architectural designs, or marine structures, the alloy you choose determines the quality of extruded aluminium profiles.

Incorporating the proper alloy composition is not merely a choice; it is a strategic decision to ensure that your extruded aluminium profiles have the intended characteristics and performance. Remember this the next time you consider an aluminium extrusion project: the alloy you select can make all the difference.
