3003 Aluminum Sheet Plate
3003 aluminum sheet plate belongs to the Al-Mn series anti-rust aluminum alloy, which is the most widely used anti-rust aluminum category in the industrial field. Its strength is only slightly higher than that of industrial pure aluminum, with an overall medium strength level. With balanced corrosion resistance, formability and weldability, it adapts to the material requirements of multiple general industrial scenarios, and has large-scale applications ranging from ordinary civil components to industrial storage and transportation equipment.
MESSAGE
Overview
3003 is 3xxx‑series Al‑Mn anti‑rust aluminum alloy. It delivers slightly higher strength than 1xxx‑series commercial pure aluminum and acts as a highly universal anti‑rust sheet material for industry. Featuring balanced formability, weldability and atmospheric corrosion resistance, it can be manufactured into mill sheet, tread plate, color‑coated sheet, corrugated sheet and other variants. It is widely applied in architectural decoration, heat‑exchange equipment, new‑energy batteries, transportation, signage, and chemical facilities.

Feature
Good anti‑rust & corrosion resistance: As a typical anti-rust aluminum, It can maintain good stability in conventional media such as atmosphere, fresh water, seawater, food, organic acid, gasoline and neutral inorganic salt solution, adapting to various usage scenarios with humid environment or slight corrosion risk.
Excellent forming performance: Soft O‑annealed temper features superior ductility for deep drawing, bending and spinning to produce complex stamped parts. Various H‑hardened tempers cover components ranging from flexible forming to moderate‑rigidity applications.
Dependable weldability: Compatible with MIG / TIG and spot welding with stable joint performance for leak‑free splicing of tanks, air ducts and carriage panels.
Medium strength plus lightweight benefit: Higher strength than pure aluminum with density only 1/3 of steel, reducing dead‑weight for low‑to‑medium load components.
Wide surface‑treatment compatibility: Readily accepts painting, color‑coating, and anodizing with uniform color finish for architectural and signage aesthetic requirements.
High comprehensive cost‑efficiency: Mature manufacturing technology and stable supply, lower cost compared with 5xxx‑series alloys, ideal for mass civil and industrial projects.
Rich customizable variants: Tread, corrugated and extra‑wide formats are available to meet diverse structural demands such as anti‑slip flooring, roofing and curtain‑wall cladding.
Application
3003 aluminum sheets are widely used for curtain‑wall liners, corrugated roofing sheets, ceilings and exterior decorative panels; radiator, condenser and heat‑exchange fins for air‑conditioning; power‑battery water‑cooling plates, battery housings and protective plates; rail‑transit carriage liners, wagon panels and container inner sheets; substrates for outdoor traffic signs and advertising billboards.
