1060 Aluminium Chemical Properties

Aluminum A91060 is composed primarily of aluminum, with trace amounts of other elements such as zinc and silicon. Unlike pure aluminum, this alloy has unique characteristics that can be attributed to its chemical composition, making it especially attractive for manufacturers. For one thing, Aluminium 1060 has a very high level of mechanical strength yet impressive malleability; this makes it particularly useful in projects where structural integrity and stability need to be maintained while allowing a certain degree of flexibility. This alloy also provides good corrosion resistance to oxidation and sulfidation due to its excellent passivation qualities; surface treatment can further increase its durability even when exposed to highly corrosive materials. Consequently, Aluminium Alloy 1060 is often used in industrial manufacturing processes that require reliable materials with precise chemical properties.

UNS A91060  Aluminium Physical Properties

The physical properties of  UNS A91060 make it an incredibly versatile material. It is highly durable and has exceptional corrosion resistance due to its alloying elements, including copper, manganese, and magnesium. With a relatively low density compared to steel and other metals, it is also lightweight and can bear large amounts of stress. Its tensile strength is high at 100-160 Nmm2, which makes it ideal for applications requiring strength and resilience, such as in reinforcing walls or rivets in aircraft. 1060 Alloy has excellent thermal conductivity thanks to its intrinsic metallic properties, so it’s great for use in most heat transfer operations, such as radiators and electrical components.

1060 Aluminium Uses

Due to its impressive UNS A91060 mechanical properties, Aluminium 1060 is used extensively in the automotive industry for components such as body panels, bumpers, and wheels. It’s also commonly used in aircraft construction due to its light weight and ability to withstand extreme temperatures. Additionally, it’s often used in electrical applications due to its high conductivity and low-resistance properties.

Aluminium 1060 Heat Treatment & Machining

1060 Aluminum can be heat-treated for increased hardness or machined for increased precision. When heat is treated properly, it can achieve Rockwell C values between 31-48 HRC (Rockwell C hardness scale). When machined properly, it can achieve tolerances as low as 0.001 inch with no loss in accuracy or precision over time due to wear or temperature changes.

AL 1060 Heat Resistance

UNS A91060 Aluminium is popular for many projects due to its excellent heat resistance properties. It can withstand extreme temperatures without succumbing to warping, cracking, or melting, making it ideal for applications involving intense heat. Furthermore, this metal has great strength and formability, allowing businesses and DIYers to craft their components without worrying about the effects of high temperatures on the finished product. With the right know-how and skilled craftsmanship, alloy 1060 aluminium can be used confidently in projects requiring prolonged exposure to high temperatures.

Aluminium 1060 Corrosion Resistance

AL 1060 is a metal alloy recognized for providing excellent corrosion resistance. It is non-heat treatable aluminum and is a popular material for many industrial applications due to its strength and corrosion resistance properties. Its low density and excellent thermal conductivity make it an ideal solution for lightweight construction and improved heat dissipation in high-temperature environments, such as foundry casting or automotive parts. Its excellent corrosion resistance is attributed to its relatively high content of aluminum which adds tough passive layers on the material’s surface, making it resistant to environmental elements such as water or saltwater. Aluminum 1060 is a highly cost-effective choice as it has significant life-cycle savings over products with lower corrosion resistance properties.


While many different aluminum alloys are available on the market today, few are as versatile as Aluminium 1060. From automotive parts to aircraft components and electrical applications, this remarkable alloy has proven itself time and time again with its impressive combination of strength, corrosion resistance, heat resistance, ductility, machinability, and conductivity. If you have an application that requires any variety of these features, then you should certainly consider using Aluminium 1060—it might just be the perfect fit!
