ASTM B209 Aluminum Plate

 

ASTM B209 is the ASTM specification covering aluminum and aluminum-alloy sheet and plate products in various alloys and tempers. Jude Steel supplies ASTM B209 aluminum plate and sheet in commonly requested grades including 5052, 5083, 5086, 6061 and 7075, with customized thickness, width, length, temper and processing options.
ASTM B209‑compliant aluminum plate finds wide application in aerospace, construction, transportation and general‑industry sectors. This standard defines chemical composition, mechanical properties and dimensional tolerances to guarantee consistent quality for various alloys and tempers.
 

 

ASTM B209/B209M covers aluminum and aluminum-alloy sheet and plate produced as wrought flat products.

Product	Typical Description
Aluminum Sheet	Relatively thin flat aluminum product
Aluminum Plate	Thicker flat aluminum product
Aluminum Alloy Sheet	Alloy-specific sheet
Aluminum Alloy Plate	Alloy-specific plate
Cut-to-Size Plate	Plate processed to customer dimensions

 

 

The distinction between aluminum sheet and plate depends on product thickness and the applicable specification. ASTM B209/B209M provides requirements for both forms, while the applicable dimensional and mechanical requirements vary according to alloy, temper and product size.
 

 

Alloy Series	Main Alloying Element	Typical Grades	Typical Characteristics
1xxx	Aluminum	1050, 1060, 1100	High purity, conductivity
2xxx	Copper	2024	High strength
3xxx	Manganese	3003	Formability, corrosion resistance
5xxx	Magnesium	5052, 5083, 5086	Corrosion resistance, weldability
6xxx	Mg + Si	6061, 6063	Strength, machinability
7xxx	Zinc	7075	Very high strength

 

The chemical composition of ASTM B209 aluminum plate and sheet is determined primarily by the specific aluminum alloy designation, rather than by ASTM B209 as a single universal composition. ASTM B209/B209M establishes requirements for aluminum and aluminum-alloy sheet and plate, while the applicable alloy designation determines the required limits for individual elements.
 

Chemical Composition Is Determined by Alloy

Different aluminum alloys have different chemical composition requirements. For example:

Alloy	Main Alloying Elements	Typical Characteristics
1050	Aluminum	High purity and electrical conductivity
3003	Manganese (Mn)	Good formability and corrosion resistance
5052	Magnesium (Mg), Chromium (Cr)	Excellent corrosion resistance and weldability
5083	Magnesium (Mg), Manganese (Mn), Chromium (Cr)	High strength and marine corrosion resistance
6061	Magnesium (Mg), Silicon (Si), Copper (Cu)	Good strength and machinability
7075	Zinc (Zn), Magnesium (Mg), Copper (Cu)	Very high strength

 

Chemical Composition of 5052 Aluminum

For example, when supplying ASTM B209 5052 aluminum plate, the chemical composition is checked against the requirements applicable to Alloy 5052. Typical limits include:

Element	5052 Requirement (%)
Silicon (Si)	≤ 0.25
Iron (Fe)	≤ 0.40
Copper (Cu)	≤ 0.10
Manganese (Mn)	≤ 0.10
Magnesium (Mg)	2.2–2.8
Chromium (Cr)	0.15–0.35
Zinc (Zn)	≤ 0.10
Aluminum (Al)	Remainder

 

 

The mechanical properties of ASTM B209 aluminum plate and sheet are determined by the specific alloy, temper, product thickness, and applicable ASTM requirements. ASTM B209/B209M does not assign one universal set of mechanical properties to all aluminum plates. Instead, minimum or required values are specified for particular alloy and temper combinations.
 

Alloy and Temper Have a Major Effect

The same aluminum alloy can have significantly different mechanical properties in different tempers.

For example:

Alloy / Temper	Condition	Typical Performance
5052-O	Annealed	High ductility and formability
5052-H32	Strain hardened and stabilized	Higher strength with good formability
5052-H34	More heavily strain hardened	Higher strength than H32
5083-H116	Marine-use temper	High strength and corrosion resistance
6061-T6	Heat treated and artificially aged	High strength
6061-T651	T6 + stress relieved	High strength and improved dimensional stability
7075-T651	Heat treated and stress relieved	Very high strength

 

 

ASTM B209/B209M covers aluminum and aluminum-alloy sheet and plate products in different alloys and tempers. Therefore, the complete specification of an ASTM B209 aluminum plate should include the alloy, temper, thickness, width, length, surface condition, and applicable dimensional requirements.

ASTM B209/B209M and ASTM B928/B928M are both ASTM standards for aluminum and aluminum-alloy flat products, but they serve different purposes. ASTM B209 is the general specification for aluminum and aluminum-alloy sheet and plate, while ASTM B928 contains additional requirements for high-magnesium marine-use aluminum sheet and plate.

Mechanical requirements	Alloy/temper/thickness dependent	Alloy/temper/thickness dependent
Product form	Sheet and plate	Sheet and plate
Marine service	May be applicable depending on alloy and requirements	Specifically intended for high-Mg marine-service products

ASTM B209 aluminum plate and sheet are used across a wide range of industrial applications because different aluminum alloys and tempers offer combinations of low weight, corrosion resistance, strength, weldability, formability, and machinability. The appropriate alloy and temper should be selected according to the required mechanical properties and service environment.
 

Marine Equipment

5052, 5083 and 5086 aluminum plates are commonly selected for marine-related applications because of their corrosion resistance and weldability.
 

Chemical Processing and Storage Tanks

5xxx and 6xxx series aluminum plates can be used for selected chemical processing and storage applications where their corrosion resistance and fabrication characteristics are suitable.
 

Transportation Equipment

The combination of low density and good strength-to-weight ratio makes aluminum plate useful in transportation equipment.
