A Closer Look At 5083 Aluminum

One of the most interesting things about different options in aluminum alloys is that each offers unique properties and characteristics. This is why aluminum is so popular and can be found in everything from computer components to aerospace applications.

There are also specific applications where a particular type of alloy is a better choice than another. Over time, a full spectrum of both cast and wrought aluminum alloys has been developed, each with their own unique properties.

Generally, for precision types of applications and uses, cast aluminum is considered the best option. This allows for very precise heating, pouring and cooling that can be used to limit any internal stress while also creating a product that is dimensionally stable. 5083 aluminum is a very good option for this type of plate that offers excellent dimensional stability for a very consistent product.

The Perks

There are several different benefits, considerations or factors to use when selecting 5083 aluminum over other cast aluminum plate options. This is an alloy that is considered to have higher than average to exceptional thermal conductivity. This factor makes it a popular option for molds, and when this is combined with the excellent corrosion resistance of the alloy it becomes a very natural first choice.

While used in jigs, molds and parts, it is also a popular option for marine use as well. This is also an alloy that can be found in pressure tanks and vessels, storage tanks for chemicals as well as on drilling rigs and industrial equipment parts and components.

The most prominent alloying ingredients in 5083 are magnesium, silicon, iron and manganese followed by zinc. This combination provides 5083 aluminum with the very high corrosion resistance that makes it such an optimal alloy selection for marine applications and any times where it will need to be exposed to highly corrosive environments.

This is also an alloy that is a good option for hard anodizing processes, further enhancing the surface protection of the aluminum. With this added protection this alloy can last significantly longer in any type of environment.

Finally, when the part or component will need to be welded, the choice of 5083 alloy is a good option. This is one of the aluminum alloys that can be welded using WIG/MIG processes as well as resistance welding and it will not lose its natural strength or require additional working after welding.
