Ordered Thickness, inches Tolerance (inch)
Minus Plus 1/
0.500 to 0.625, incl 0.025
0.626 to 0.875, incl .030
0.876 to 1.125, incl .035
1.126 to 1.375, incl .040

1/ The values for the plus column are derived from the full range of tolerances specified (for sheet and plate not specified for aerospace applications) in table 3.1 of ANSI H35.2 less the value shown in the minus column. For example, the plus tolerance on a 2.0 inch thick by a 73 inches wide plate would be as


Thickness tolerance (from ANSI H35.2) ±0.060"

Tolerance value shown in minus column 0.060"

Full tolerance less minus tolerance 0.120" - 0.060" = 0.060"

Derived plus tolerance 0.000"

Characteristics of 7039 aluminum armor plate

High strength: 7039 aluminum alloy armor plate has excellent strength, which can provide excellent impact resistance and penetration resistance. It is widely used in military and protection fields, and can withstand high pressure and external impact.

Lightweight: despite its high strength, 7039 aluminum alloy armor plates are relatively lightweight, having a higher density to strength ratio than other materials such as steel. This makes it advantageous in applications where weight reduction is required, such as in aerospace.

Good corrosion resistance: aluminum alloy has good corrosion resistance and can resist common corrosion factors such as water, moisture, acid and alkali. This allows the 7039 aluminum alloy armor plate to maintain its performance and appearance during long-term use in harsh environments.

Easy to process and form: 7039 aluminum alloy armor plate can be processed and formed by hot rolling, cold rolling, forging, welding and other processes. This makes it suitable for application needs in different shapes and sizes, and to meet specific design requirements.

Stable performance: 7039 aluminum alloy armor plate has good stability at different temperatures and can maintain its strength and performance. This allows it to function reliably in a wide range of environmental conditions.

Note that specific features may vary by manufacturer and product specification. If you have specific needs, it is recommended that you contact the supplier or manufacturer directly for accurate and detailed information.

Key points for choosing 7039 aluminum alloy armor plate

Specifications and dimensions: determine the desired thickness, length and width of the armor plate to ensure that it meets your specific application needs. Different applications may require armor plates of different sizes and thicknesses.

Strength requirements: determine the strength level of armor plate you need to meet specific protective performance requirements. Different armor plate strengths can vary according to application requirements.

Surface treatment: find out if an armor plate requires a specific surface treatment such as blasting, coating, etc. to enhance its corrosion resistance or increase adhesion.

Certification and quality standards: make sure the selected armor plate complies with relevant certification and quality standards, such as military standards or international standards, to ensure its quality and reliable performance.

Supplier reputation and experience: choose a supplier with reputation and experience, they can provide high-quality 7039 aluminum alloy armor plate, and can provide technical support and after-sales service.

Prices and lead times: compare prices and lead times between different suppliers to ensure you are getting quality products with reasonable prices and proper lead times.

Testimonials and case studies: view vendor testimonials and case studies to learn about their experience and performance on similar projects.

When choosing 7039 aluminum alloy armor plate, it is also very important to communicate with suppliers and get their professional advice to ensure that you choose the product that best suits your needs.
