Aluminum Coil 3003 H14 H16 H18 to ASTM B209
Aluminum coils are a crucial component in various industries, and one of the most popular grades is Aluminum Coil 3003. Known for its excellent corrosion resistance, workability, and formability, Aluminum 3003 is commonly available in several tempers — namely H14, H16, and H18. In this article, we delve into the specifics of Aluminum Coil 3003 and how it complies with ASTM B209 standards.
What is ASTM B209?
ASTM B209 is the Standard Specification for Aluminum and Aluminum-Alloy Sheet and Plate for General Applications. This standard ensures that aluminum products meet specific mechanical and chemical properties, making them reliable for use in a variety of applications. Compliance with ASTM B209 signifies that the material has undergone rigorous testing to guarantee its quality and performance.
Grades of Aluminum Coil 3003
Aluminum Coil 3003 is part of the 3000 series and contains manganese as its primary alloying element. This alloy is renowned for its excellent workability and is often used in its H-tempers, including H14, H16, and H18. Understanding these tempers is essential for selecting the right coil for your applications.
Aluminum Coil 3003 H14
The H14 temper indicates that the aluminum coil has been strain-hardened and partially annealed. This results in a material that provides good strength and excellent corrosion resistance, making it suitable for applications such as:
- Fuel tanks: The ability of Aluminum 3003 H14 to resist corrosion enhances the longevity of fuel storage.
- Chemical equipment: Its resistance to various chemicals makes it ideal for tanks and other chemical storage solutions.
The tensile strength of Aluminum 3003 H14 generally ranges from 110 to 125 MPa, making it a reliable choice for general-purpose applications.
Aluminum Coil 3003 H16
With a slightly higher strength than its H14 counterpart, Aluminum 3003 H16 temper is ideal for applications requiring a balanced combination of strength and ductility. The tensile strength of this temper typically ranges from 125 to 135 MPa.
Common applications include:
- Cooking utensils: Its excellent thermal conductivity and formability make it perfect for pots and pans.
- Heat exchangers: The alloy's thermodynamic properties ensure efficient heat transfer.
Aluminum Coil 3003 H18
The H18 temper provides the highest strength within the Aluminum 3003 series, with a tensile strength of approximately 140 to 150 MPa. While it is less ductile compared to H14 and H16, it is ideal for applications where stronger materials are necessary.
Key applications include:
- Structural components: The durability of the H18 temper allows it to thrive in structural applications requiring high strength.
- Automotive and aerospace applications: Thanks to its lightweight and high strength, it is increasingly used in the manufacturing of automotive parts and various aerospace components.
