Aluminium extrusions or profiles refer to aluminium products produced via the extrusion process. Aluminium extrusions are formed by pushing aluminium billet sections through a steel die with specific cross-section profile. At Chip Aik we offer a wide range of aluminium extrusions – geometric shapes, architectural profiles and customised profiles. Visit our product page here to view our product range.
We keep stock of aluminium extrusions in alloy 6063-T5, and aluminium sheets in A1100-H14. However, if you require other aluminium alloys such as 6061-T6, 6082-T6, 3003, feel free to contact us here and our friendly sales team will follow up from there.
It depends on the final usage and application of the material. For example, alloy 6063-T5 is the most common alloy and it is mostly use for architectural and façades because its smooth surface allow for further processing to create an aesthetically pleasing look. However, if you require a high strength, 6061-T6 alloy will be a better choice compared to 6063-T5 (i.e. higher ultimate tensile strength and yield strength). 6061-T6 aluminium alloy is commonly used for structural applications.
Mill finish refers to the surface texture (or finish) of aluminium straight from the mill, without any additional treatment or finishes applied. It has a dull, slightly rough texture and can vary in appearance depending on the alloy and manufacturing process used.
Anodized aluminium, on the other hand, is a surface treatment that involves an electrolytic process to grow oxide layer on the aluminium surface for enhanced protection. This process creates a hard, durable, and corrosion-resistant finish that can be dyed a variety of colours. Anodized aluminium also has a smooth, shiny finish.
To summarize, the main differences between mill finish and anodized aluminium are the surface texture, appearance, and level of protection against corrosion. While mill finish is more affordable and can be used for a wide range of applications, anodized aluminium provides added durability, colour options, and corrosion resistance, making it suitable for use in harsh environments or where aesthetics are important.
Yes, Aluminium is highly recyclable. It can be recycled indefinitely without losing its properties, which makes it an environmentally sustainable material. Recycling Aluminium requires only a fraction of the energy and resources needed to produce new Aluminium from raw materials. This is because the recycling process involves melting down the Aluminium scrap to create new Aluminium products, which saves energy and reduces greenhouse gas emissions.
In fact, Aluminium is one of the most recycled materials in the world. It is estimated that over 75% of all Aluminium ever produced is still in use today, thanks to the recycling process. Aluminium cans, for example, are the most commonly recycled consumer product in the world. When Aluminium cans are recycled, they can be turned into new cans in as little as 60 days.
