Introduction
Aluminum 7075 is an aluminum alloy that provides excellent strength and durability. It is composed of zinc as the primary alloying element and can also contain traces of magnesium, copper, and chromium. Aluminum 7075 is known for its corrosion resistance, lightweight, and high strength-to-weight ratio. It is often used in the aerospace, automotive, and marine industries due to these properties.
Properties and Uses of Aluminum 7075
Aluminum 7075 is one of the strongest aluminum alloys available, with a yield strength of 73,000 psi and a tensile strength of 83,000 psi. It is also highly resistant to corrosion, making it a popular choice for many applications. Additionally, aluminum 7075 is lightweight and has a good strength-to-weight ratio, which makes it suitable for use in aircraft and other transportation vehicles.
Aluminum 7075 is widely used in the aerospace industry, particularly for aircraft structural components, especially landing gear and fuselage frames. It is also commonly used in the automotive industry for car and truck frames and suspension components. In the marine industry, aluminum 7075 is often used for boat hulls and outboard motor parts.
How Aluminum 7075 Is Manufactured
Aluminum 7075 is manufactured through a process called extrusion. During this process, raw materials are melted and then forced through a die to create a specific shape. The raw materials used in the manufacture of aluminum 7075 include aluminum, zinc, magnesium, copper, and chromium. These materials are blended together in specific proportions to achieve the desired properties.
Once the raw materials are blended, they are heated to a certain temperature and then forced through a die. This process creates a solid aluminum bar or rod with a specific shape and size. The bar or rod can then be cut into smaller pieces for use in various applications.
Applications for Aluminum 7075 in Aerospace, Automotive and Marine Industries
Aluminum 7075 is commonly used in the aerospace, automotive, and marine industries due to its strength, durability, and corrosion resistance. In the aerospace industry, aluminum 7075 is often used for aircraft structural components such as landing gear and fuselage frames. In the automotive industry, aluminum 7075 is often used for car and truck frames and suspension components. In the marine industry, aluminum 7075 is often used for boat hulls and outboard motor parts.
Benefits of Using Aluminum 7075
Aluminum 7075 has several benefits over other metals, including cost effectiveness, low maintenance, and versatility. Aluminum 7075 is relatively inexpensive when compared to other metals, making it a cost effective solution for many applications.
