3003 aluminum rounds introduction
3003 aluminum disc series is the most commonly used aluminum sheet and strip product of aluminum-manganese alloy series. Usually because 3003 aluminum discs have aluminum and manganese elements, so this 3003 aluminum disc product is also usually called rust-proof aluminum plate, rust-proof aluminum skin. However, the ratio of 3003 aluminum round sheet is larger than the conventional 1060 aluminum sheet.
Due to the infusion of aluminum and manganese elements, the strength of 3003 aluminum rounds is higher than that of conventional 1060 aluminum sheet. Therefore, the hardness and strength of 3003 aluminum discs are about 10% higher than 1100 aluminum plate and 1060 aluminum plate. In addition, the solubility, formability, and excellent corrosion resistance of 1060 aluminum sheet. For these reasons, 3003 aluminum rounds for insulation are gradually becoming popular in the market, and more and more people are introducing 3003 aluminum rounds.

Characteristics of 3003 aluminum discs
3003 is an AL-Mn alloy, which is a kind of rust-proof aluminum with wide application. The strength of this alloy is not high (slightly higher than industrial pure aluminum) and cannot be strengthened by heat treatment, so cold working method is used to improve its mechanical properties: high plasticity in annealed state, still good plasticity in semi-cold hardening, low plasticity in cold hardening, good corrosion resistance, good weldability, poor machinability. Uses are mainly used for the requirement of high plasticity and good weldability, low load parts working in liquid or gas medium, such as oil tanks, gasoline or lubricating oil conduits, various liquid containers and other small load parts made by deep drawing: wire is used to make rivets.

Density of 3003 aluminum rounds.
Elongation of 3003 aluminum discs.
Since 3003 aluminum rounds have aluminum and manganese elements, 3003 aluminum rounds are much harder than 1060 aluminum sheet and 1100 aluminum sheet in terms of hardness. Therefore, the elongation of 3003 aluminum rounds is generally not as good as 1060 aluminum plate. In general, 3003 aluminum rounds are about 10% harder than 1060.
