Learn about stamped aluminum sheet

Aluminum alloy is a lightweight, high-strength and recyclable metal material. Aluminum alloy stamping technology is a processing method that uses aluminum alloy sheets as materials and processes them into parts and components to form finished products through processes such as horizontal stamping and heat treatment. 

Stamped aluminum sheets are aluminum sheets suitable for stamping. This article will explore the material characteristics of stamped aluminum sheets, the aluminum alloy grades and usage conditions suitable for stamping, and the application range of stamped aluminum sheets.

Characteristics of stamped aluminum sheet

• 1. Low density and light weight: The density of aluminum alloy is relatively small, which makes the stamped products lighter at the same volume.
• 2. Small thermal expansion coefficient: The thermal expansion coefficient of aluminum alloy is relatively small, which makes the stamped products have better dimensional stability under high temperature environment.
• 3. Good thermal conductivity: The thermal conductivity of aluminum alloy is good, which is conducive to heat dissipation, reduces heat accumulation, and improves the service life of stamped products.
• 4. Easy to process: Aluminum sheets suitable for stamping generally have good processing performance and can be made into parts of various shapes and sizes through various process means.
• 5. Recyclable: Aluminum alloy is a recyclable material, which is conducive to environmental protection and sustainable development.

Common states of stamped aluminum sheets

Aluminum sheets are usually used in the following states during the stamping process:

◆ O state (annealed state): has good ductility and is suitable for stamping of complex shapes.

◆ H14/H24 state: after partial hardening treatment, the strength and toughness are balanced, suitable for general stamping applications.

◆ H18/H28 state: after full hardening treatment, the strength is high, but the ductility is poor, suitable for stamping parts of simple shapes.

Common applications of stamped aluminum sheets

• 1. Automobile manufacturing: used to manufacture automotive parts, such as doors, windows, hoods, etc.
• 2. Aerospace: used to manufacture aircraft parts and spacecraft structural parts.
• 3. Construction field: used to manufacture building components and structural parts, such as doors, windows, beams and columns, etc.
