Product Introduction
A forged aluminum alloy bar, such as the 2618 aluminum alloy forged bar, is a type of metal produced through a process known as hot working. The process involves forging or compressing molten or near-molten metal into a specified shape using powerful presses. The end result is a bar or rod of a strong, highly corrosion resistant and heat-treatable material.
Product Chemical Composition
In the context of 2618 aluminum alloy, the composition of this material includes 93% aluminum,4.9%copper, and 1.1% magnesium. This combination of elements gives the material excellent physical characteristics. It is highly corrosion resistant and provides a combination of strength and ductility that can be increased through heat treatment. The material is also comparatively easy to work with and can be cold rolled, formed, machined, welded, and most other conventional methods of fabrication.
Product performance
Compared to other non-heat treatable aluminum alloys, such as 3003 and 6061 alloys, forged bars from 2618 aluminum possess greater yield and tensile strength. For example, annealed wrought bars from 2618 aluminum alloy have ultimate tensile strength of 59 ksi and yield strength of 43 ksi. In comparison, annealed wrought bars from 6061 aluminum alloy have ultimate tensile strength of 45 ksi and yield strength of 40 ksi.
Product advantages and applications
2618 aluminum alloy forging bars are primarily used in aerospace and automotive applications where greater strength and higher fatigue resistance are required than provided by other aluminum alloys. In these fields,2618aluminum offers the highest strength of any aluminum alloy with temperatures up to 150 degrees F. It also has exceptional weldability and machinability characteristics.
Forging 2618 aluminum alloy into bars also creates a material with greater corrosion resistance. In fact, this material can even resist corrosion in environments that are typically extremely corrosive, such as salt water, saline, and acidic alkaline solutions. The corrosion resistance makes it an ideal choice for components exposed to harsh environments.
To summarize,2618 aluminum alloy forged bars offer an excellent combination of strength, ductility, and corrosion resistance. The material is used in aerospace, automotive, and chemical industries, as well as in other applications where high strength and corrosion resistance is needed. Thanks to its great weldability and machinability characteristics, it can be easily processed and fabricated into a variety of shapes and sizes.
