Mechanical Properties
The mechanical properties of 3003 Aluminum Sheet are closely related to its processing state (temper), and different tempers are designed to meet diverse strength and ductility requirements. The following are the key mechanical performance indicators of typical tempers:
O State
Full Annealed — Tensile strength (σb): 90–130 MPa | Yield strength (σ0.2): ≤ 40 MPa | Elongation (δ): ≥ 25%. Best ductility; suitable for complex forming processes such as deep drawing, bending, and stamping.
H14 State
Strain Hardened + Partial Annealed — Tensile strength (σb): 130–180 MPa | Yield strength (σ0.2): 110–150 MPa | Elongation (δ): ≥ 5%. Balances strength and formability; widely used in structural parts requiring moderate strength.
H18 State
Full Strain Hardened — Tensile strength (σb): ≥ 180 MPa | Yield strength (σ0.2): ≥ 160 MPa | Elongation (δ): ≥ 3%. Highest strength; suitable for load-bearing components that do not require secondary forming.

Frequently Asked Questions
QWhat is 3003 alloy aluminium sheet and what makes it different from other aluminium alloys?
A3003 aluminium sheet belongs to the Al-Mn series (3xxx series) and is one of the most widely used aluminium alloys. Its manganese content (approximately 1.0–1.5%) gives it approximately 20% higher strength than pure aluminium (1xxx series), while still maintaining excellent formability, corrosion resistance, and weldability — making it ideal for a broad range of industrial and commercial applications.
QWhat tempers are available for 3003 aluminium sheet, and how do I choose the right one?
A3003 aluminium sheet is available in a wide range of tempers including O, H12, H14, H16, H18, H22, H24, and H26. The O temper offers the best ductility for deep drawing and complex forming. H14 provides a balance of strength and formability for general structural parts. H18 delivers the highest strength for load-bearing applications that do not require further forming. Choosing the right temper depends on your required strength level, forming process, and end-use environment.
QWhat are the main application fields of 3003 aluminium sheet/plate?
A3003 aluminium sheet is used across a wide variety of industries, including the construction industry (roofing, cladding, facades), automotive and transportation (body panels, fuel tanks), kitchenware and daily necessities (cookware, containers), industrial equipment (heat exchangers, pressure vessels), and the packaging industry (cans, foil packaging). Its combination of corrosion resistance, workability, and moderate strength makes it highly versatile.
QWhat thickness and size range is available for 3003 aluminium sheet?
A3003 aluminium sheet is available in thicknesses ranging from 0.2 mm to 200 mm, with diameters from 50 mm to 1200 mm. Both CC (Continuous Casting) and DC (Direct Chill Casting) processes are supported, allowing the product to meet a wide range of thickness, surface quality, and mechanical property requirements for different applications.
QWhat are the tensile strength and yield strength values for 3003 aluminium sheet in H14 temper?
AIn the H14 temper (strain hardened + partial annealed), 3003 aluminium sheet has a tensile strength (σb) of 130–180 MPa and a yield strength (σ0.2) of 110–150 MPa, with an elongation (δ) of ≥ 5%. This temper is widely chosen for structural parts that require moderate strength along with reasonable formability.
QIs 3003 aluminium sheet suitable for welding and corrosion-resistant environments?
AYes. 3003 aluminium sheet offers excellent weldability and can be joined using common methods such as MIG, TIG, and resistance welding. It also demonstrates outstanding corrosion resistance, particularly in atmospheric, freshwater, and mild chemical environments, making it a reliable choice for outdoor construction, food-contact applications, and industrial equipment exposed to moisture or mild corrosives.
