Aluminum is a silvery-white metal and is the most abundant metallic element on earth. The metal is appropriate for forging as it is easy due to low flow strength at forging temperature. One of the methods used to forge the metal is closed die forging. This is the process where hot metal is forged into a distinct shape by pressing two shaped metal plates against a workpiece force. It is the best forging process for aluminum as it quickly fills the cavities.
Closed-Die Forging Benefits
Aluminum is an inexpensive and popular non-ferrous metal utilized in closed die aluminum forging. This is because of its flexibility, elevated strength-to-weight ratio, versatility with alloying components, and lower melting point. The metal heats and cools quickly and can be transformed in a singular die than steel.
Reasons for using closed die forging for aluminum components
• It’s an economical production method of creating and designing aluminum parts and components in mass production. Through it, you can avoid machining and achieve a high production rate. In addition, designs can be made that don’t need joints and welds.
• You can achieve a high strength to weight ratio. The closed die forging process produces a fully wrought structure that improves the shock and fatigue resistance.
• The process gives you a good surface finish, and there’s the elimination of porosity to ensure tightness.
Aluminum forgings are used in highly stressed parts due to their excellent mechanical properties, dimensional accuracy, and surface finish. Various industries use aluminum components, but the aerospace sector’s principal user. Other sectors where aluminum alloys are used include electronic module packaging, electronic technology, wind, and solar energy, and automotive body structure.
Aluminum is a metal that is widely used in various industries. It’s because it’s one of the most abundant non-ferrous metals and has a high strength-to-weight ratio.
