3000 Series Aluminum Sheets, Plates & Coils – Prime Performance Alloys

The 3000 series aluminum is alloyed primarily with manganese (1.0 – 1.5 %), which gives it higher strength than 1000 series, while maintaining excellent formability, weldability, and corrosion resistance.

Common alloys include 3004, 3105, used widely in HVAC, roofing, building cladding, signage, kitchenware, and automotive trim.

YUQI Metal offers 3000 series aluminum in coils, sheets, plates, with optional patterned / embossed surfaces and tailored dimensions to satisfy your project needs.

3000 series aluminum plate can also be called rust-proof aluminum plate, representing 3003, 3105, 3A21 mainly. 3000 series aluminum plate production process is more excellent. 3000 series aluminum plate is made of manganese element as the main component. The content is between 1.0-1.5, which is a series with good anti-rust function. It is commonly used in humid environments such as air conditioners, refrigerators, and cars, and the price is higher than the 1000 series, which is a more commonly used alloy series.

3003 Aluminum properties

Alloy Characteristics

3003 is a widely used manganese-alloyed aluminum (about 1.0–1.5 % Mn) that is non-heat-treatable and gains strength through cold working. It features:

• Excellent formability (can be bent, stamped, drawn, spun).

• Good weldability (compatible with MIG, TIG, resistance welding).

• Strong corrosion resistance, especially in atmospheric and mild chemical environments.

• Moderate strength: higher than pure aluminum, but softer than many alloyed series.

Temper	3003-O	3003-H14	3003-H22
Shear Strength	75MPa	96MPa	81MPa
Tensile Strength	40-110MPa	130-160MPa	94-140MPa
Elastic Modulus	70GPa	70GPa	70GPa
Hardness Brinell	28HB	42HB	37HB
Elongation	28%	8%	8%

Forms: Sheet / Coil / Plate

• 3003 Sheet & Coil: commonly used in thin-gauge applications; easy to decorate or coat.

• 3003 Plate: thicker sections for structural or semi-structural use; still retains good workability.

• 3003 Foil / thin roll: very thin gauge for specialty uses like lamination or packaging.

Typical Applications

YUQI METAL can supply 3003 aluminum sheet, thick plate, patterned (embossed) plate, foil roll, and supports custom dimensions and treatments.

3105 Aluminum properties

Alloy Characteristics

3105 is also a manganese alloy in the 3000 series. Key properties:

• Higher strength than 3003, while maintaining good formability and corrosion resistance.

• Not hardenable by heat treatment; strengthened by cold work only.

• Excellent surface finish and compatibility with coatings, making it favorable for decorative and architectural uses.

Temper	Mechanical properties
	Tensile strength (MPa)	Elongation (%)
H14	160-190	≥1
H24		≥4
H16	175-225	≥1
H26		≥3
H18	≥195	≥1

Forms: Sheet / Coil / Plate

• 3105 Sheet & Coil: widely used in coated or painted sheet metal markets.

• 3105 Plate: thicker plates for structural or semi-structural components where higher strength and surface quality are needed.

• 3105 Substrate / coil for caps: used as raw stock for making caps or closure materials.

Typical Applications

• Bottle caps / closures: beverage bottle caps, cosmetic bottle caps — 3105 is widely used due to its formability and coating compatibility.

• Coated / decorative panels: room partitions, wall cladding, color-coated aluminum substrates, lamp holders, blinds, shutter panels.

• Architectural & exterior use: roofing, facade panels, exterior wall coverings, downspouts, eaves.

YUQI METAL can supply 3105 aluminum coils, plates, coated substrates, caps material, with ability to customize alloy temper, thickness, and finish.

FAQ

Q1: What makes 3000 series better than 1000 series?

A: 3000 series adds manganese, which improves strength by ~20% over 1000 series, while maintaining good formability and corrosion resistance.

Q2: Which alloy grades are most commonly used?

A: 3003 (most common general use), 3105 (for painted architectural panels), 3005 (slightly stronger), and 3004 (higher hardness).

Q3: Can your 3000 series materials be embossed or patterned?

A: Yes — we support embossing (diamond pattern, 5-bar, stucco, etc.), and combine with anodizing or coating as needed.

Q4: Do you accept custom sizes and small orders?

A: Yes, we offer cut-to-size services and accept small quantity orders for many products.

Q5: What certifications do you provide?

A: We supply full material test reports, certifications per ASTM, EN, GB standards, and support third-party inspections.
