Specification of a 3003 or 5052 aluminum alloy? Understand the difference
Aluminum products have always been a popular choice in the construction industry and now even more so, as a solution to the current reloading crisis in all states of Australia. With solid aluminum panels currently taking the lead, the decision of which product to use isn’t just limited to the brand name. An additional decision needs to be made on the correct aluminum series to use – 3003 or 5052.
What’s the difference and why care?
Alloy 5052 contains magnesium as the main alloy and is also known as “marine grade” aluminum. Typically used for marine applications, it is also easy to manufacture. Its corrosion resistance even in saltwater environments makes it beneficial for the Australian construction industry where the majority of developments are on a coastline or located in a corrosive environment. 5052 also has higher tensile strength and is considered a premium alloy.
This aluminum contains manganese as the main alloying element and is a moderate strength alloy. It is a much softer alloy and has less tensile and impact resistance than the 5052.
Aluminum 3003 is typically used in soft drink cans, stamps, pressure vessels, builder’s hardware, garage doors, awning slats, refrigerator panels, gas lines, tanks gasoline, heat exchangers, drawn and extruded parts and storage tanks.
These are just a few of the reasons the Queensland government specifies the 5000 series alloy on all government projects. In addition to the above, Alloy 5052 outperformed 3003 in an independent NATA approved hail test, which is a particularly important consideration for Queensland and other northern states.
At Aodeli, we considered both alloys in terms of advantages and disadvantages when developing our SAP (Solid Aluminum Panel). Based on its superior advantages, our research and development team decided to use alloy 5052 for this important and premium facade cladding product.
When it comes to the coating and grinding market in Australia, Aodeli offers architects, builders, engineers and homeowners a choice of two main products: SAP (solid aluminum panel) and NCP (non-combustible panel). Both are fully compliant and tested to Australian standards and can be used seamlessly to replace non-compliant composite panels.
