Specification and Price for Electronics Aluminum Circle

January 3, 2020

Aluminum circle discs are divided into many types based on their uses. An electronics aluminum circle is one of them. This is a circle made into a capacitor holding maze-like electronic units. The adoption of aluminium circle sheets in certain electronic products helps to extend the service life and reduce failure rate of these products.

Of Al-Mn alloy, electronics aluminum circles contains Al, Mn, Cu, Mg, Si and Fe, which are known respectively as aluminium, manganese, magnesium, silicon and iron. Magnesium and iron function to strengthen hardness of the circles that go through a special technological hardening process before being finished. The high temperature strength of the circles is improved by iron, and silicon enhances heat treatment effects of the circles. Manganese boasts a natural corrosion resistance, and it serves to improve the same ability of the circles. The variation in content of these metals leads to different mechanical properties of the circles. Take 1070 aluminum circle for batteries for example. Increasing the content of Cu and Mg will help to improve the strength and hardness of the battery case, resist the bulging of the battery, and further affect the battery performance.

Generally common aluminum discs are mainly 1050-0 or 1050 semi-rigid, made into electrical appliances and pots with good heat dissipation properties and a long service life. Higher quality electronics aluminum circles are of 3000 series, like 3003, 3004 and 3005. These round aluminium sheets will not crack during stamping and spinning during the later production process. Nowadays, there is a large demand of them in markets of Africa, America and Europe.


The price for aluminum circle ral ranges between 2300 and 3000 dollars per metric ton. Anodized and mirror finish aluminium circles might be more expensive. Welcome to contact us for more information!
