China 3003 aluminum sheet
When it comes to selecting aluminum sheets for industrial and manufacturing applications, China 3003 aluminum sheet stands out as a reliable and versatile material. Its unique blend of mechanical strength, corrosion resistance, and formability makes it the choice of modern industries spanning construction, transportation, and consumer goods.
China 3003 Aluminum Sheet: More Than Just a Metal Sheet
Unlike pure aluminum alloys, China 3003 aluminum sheet belongs to the 3xxx series, which incorporates manganese as the primary alloying element (usually about 1.0–1.5%). This element not only boosts tensile strength but also provides improved corrosion resistance and excellent workability. From an industrial functional standpoint, 3003 aluminum sheet can perform effectively under moderate stress conditions and can endure harsh external environments, making it widely adaptable.
Core Functional Attributes
Mechanical Strength & Tensile PerformanceChina 3003 aluminum sheet shows a typical tensile strength ranging from 130 MPa in fully annealed conditions to as high as 190 MPa when cold worked (e.g., H14 temper). This flexibility allows engineers to select specific tempers to optimize both machinability and durability wherever the metal is used.
Corrosion ResistanceBenefiting from naturally forming antibacterial protective oxide coatings on the aluminum surface, the 3003 aluminum sheet excels against corrosion caused by atmospheric moisture and many chemicals. This makes it ideal for applications in humid or mildly corrosive environments.
Thermal & Electrical ConductivityThough often overlooked, the moderate thermal conductivity (about 160 W/m-K) of 3003 aluminum sheet makes it useful for dissipating heat efficiently without the high cost of aluminum alloys with higher copper contents.
Formability & WeldabilityOwing to good ductility and no heat treatability, 3003 aluminum sheet offers excellent formability, achieved through tempering such as O (annealed) or H14 (work hardened). Additionally, ease of welding by gas or arc welding keeps manufacturing flexible.
