Do you need to use a lot of aluminum circle wafers? Do you buy Aluminium circles from different aluminum manufacturer or do you choose to produce them by yourself? Here are some details that need attention.
The aluminium circles are often drawn with presses into various sizes. Capacitors use small cans, whereas an aluminum circle kitchen pot would be much lager. The size and thickness of the circle are matched for the desired size and thickness of the finished product. Because aluminum is quite malleable, it makes it easier to draw to the final shape than other metals. Aluminum does not rust like steel, but it does oxidize and is often coated to prevent this.
Large users of aluminum circles may choose to purchase aluminum sheet and perform the blanking process themselves. This has a cost advantage of purchasing sheets, but requires additional material handling to deal with the scrap, since the scrap needs to be shipped back to an aluminum processing company. Additionally, the machine maintenance and space adds cost to the process, which needs to be considered when deciding to purchase discs or perform the process in-house.
