One of the most important considerations in any type of manufacturing and fabrication is the selection of the specific materials. For the manufacturing, fabrication and even for prototype development of tools, jigs and specialized components, it can be tempting to try to cut corners and go with the cheapest possible option.
The problem with this decision is the appearance of cost-saving that can end up actually being quite cost ineffective. This is particularly evident when comparing the price and benefits of quality AA5083 Cast CT&J when compared to a lower priced, lower quality type of plate.
The Difference
Quality manufacturers of AA5083 Cast CT & J ensure that the plate is manufacturing to extremely tight tolerances and the highest levels of consistency. This means that the final product has the best possible level of dimensional stability.
For the fabricator or manufacturer, this plate will be highly resistant to deformation during machining. In turn, this provides a consistent part, component, tool or jig produced every time. With limited deformation of the plate, there is also very low waste and very limited concern about using specialized machining processes to limit the stresses on the plate as it is being processed.
The best quality of the aluminum CT&J plate will be checked on a perfectly level granite table for flatnesses. The testing for flatness will be done in a randomly selected one meter square area. The best products will adhere to very tight tolerances for perfect flatness that will fall within the range of plus or minus 0.0005 to plus or minus 0.015 inches depending on the specific type of plate and flatness requirements.
The Appearance
Another factor to keep in mind is the quality AA5083 Cast CT&J, as with any type of superior aluminum alloy, will be an excellent option for hard anodizing processes. While not suitable for decorative anodizing, the hard anodizing still produces a consistent and appealing look.
Additionally, the hard anodizing creates a very durable and hard surface on the component that can withstand even highly corrosive environments with a much longer lifecycle and top aesthetics.
While not specifically related to appearance, the durability to machining and the flatness of the plate also helps to reduce the cost of processing. Fabricators and manufacturers can often avoid secondary or finishing types of processing, including rough milling and having to finish edges and surfaces.
