Learn more about the properties, benefits, and applications of these materials below.
5083-H131 Armor Plate
5083-H131 armor plate is a high-strength aluminum alloy that is especially well-suited for military applications due to its excellent ballistic resistance. Other key benefits and properties include:
- Great Strength-to-Weight Ratio. Its unique combination of strength and light weight make it ideal for everything from military vehicle armor to protective barriers.
- Corrosion Resistance. This material offers great corrosion resistance, ensuring longevity in harsh environments.
- Weldability and Formability. 5083-H131 armor plate provides good weldability and formability, allowing it to be customized to the needs of various military and defense applications.
2219-T87 Plate
This high-strength aluminum alloy is well-known for its excellent performance at elevated temperatures, making it a popular choice for aerospace applications. Advantages of 2219-T87 plate include:
- Excellent Mechanical Properties. 2219-T87 aluminum plate offers superior mechanical properties and is resistant to stress corrosion cracking. For this reason, it is commonly chosen for structural components in aircraft and spacecraft.
- Strong and Stable. This material’s ability to maintain strength and stability in extreme conditions makes it ideal for rocket and fuel tank construction.
- Weldability. 2219-T87 plate is highly weldable, facilitating easy fabrication and assembly into complex aerospace designs.
2017-T4 (7/8″ Round Bar and Under)
2017-T4 aluminum alloy is a very strong, highly machinable material commonly used for aerospace and automotive applications. It offers the following advantages:
- Performance in Demanding Conditions. This material offers good mechanical properties and is especially effective in applications requiring a high degree of durability and stress resistance.
- Machinability. 2017-T4 round bars have excellent machinability and can be easily formed into the required shape.
- Strong and Ductile. The T4 temper of 2017 aluminum results in a balanced combination of strength and ductility. This makes it a versatile choice for various precision-engineered components.
It’s important to note that this material is less corrosion-resistant than other specialty aluminum materials; however, special coatings or treatments can offer extra protection. 2017-T4 aluminum is also more prone to cracks during welding, but it can be joined using more specialized techniques.
1100-O Sheet
1100-O sheet is a commercially pure aluminum product offering excellent corrosion resistance and high thermal conductivity. Other important benefits and properties include:
- Formability and Workability. 1100-O aluminum sheet is highly formable and workable, making it ideal for applications requiring complex shapes or intricate designs. Examples include the manufacture of kitchenware, heat exchangers, and chemical storage equipment.
- Ductility. Its ductility and softness make it easy to bend, draw, or stamp.
- Flexibility. The O temper of 1100 aluminum means that it has been fully annealed, enhancing its overall flexibility and workability.
5052-O Sheet
This durable alloy provides excellent corrosion resistance, particularly in marine environments. As such, it is frequently used for shipbuilding and other coastal applications. Key advantages and properties of 5052-O aluminum sheet include:
- Formability and Weldability. 5052-O aluminum sheet offers good formability and weldability, allowing for the creation of complex structures and shapes.
- Versatility. While not as strong as other aluminum alloys, 5052-O offers an ideal balance of durability and flexibility. This makes it suitable for a wide range of applications, from fuel tanks and automotive panels to ship decks and boat hulls.
- Performance at Low Temperatures. 5052-O aluminum sheet maintains its properties at low temperatures, further expanding its range of applications such as in aircraft and marine fuel and oil lines, appliances, lighting, and more.
