Title

In modern industry, material performance directly determines product quality and durability. As one of the most popular members of the aluminum alloy family, 6061 aluminum discs are widely regarded as a preferred material across automotive, aerospace, marine, construction, and sporting goods industries. Their popularity stems from an excellent balance of mechanical strength, corrosion resistance, and machinability.

Understanding 6061 Aluminum Circle / Discs

6061 aluminum alloy belongs to the Al-Mg-Si (aluminum-magnesium-silicon) series and is a heat-treatable, precipitation-hardened alloy. Compared with commonly used 1060 or 3003 aluminum discs, 6061 contains magnesium and silicon that form the strengthening phase Mg₂Si, significantly improving mechanical strength.

Key Advantages of 6061 Aluminum Wafers

1. High Strength
   Tensile strength up to 310 MPa and yield strength up to 276 MPa, suitable for most structural applications.

2. Excellent Machinability
   Outstanding cutting performance and cold workability, ideal for turning, milling, drilling, stamping, and other precision machining processes.

3. Good Corrosion Resistance
   Particularly after anodizing, a hard and corrosion-resistant oxide layer forms on the surface, offering both protection and an attractive appearance.

4. Moderate Density with Good Conductivity
   Lightweight yet with favorable electrical and thermal conductivity, supporting efficient heat dissipation and structural optimization.

Definition of 6061 Aluminum Discs

A 6061 aluminum circle is a circular blank manufactured from 6061 aluminum plate or coil through precision stamping, CNC turning, or laser cutting. Its core value lies in providing a standardized, pre-processed base material for downstream manufacturing.

HAOMEI Aluminum supplies aluminum discs with thicknesses from 0.5-6.0 mm and diameters from 10-2000 mm, and offers multiple surface finishes such as mirror polish, brushed finish, anodizing (natural, black, etc.), and coating to fully meet customized requirements.

Manufacturing Process of 6061 Aluminum Discs

1. Casting
   The alloy is melted and poured into molds to form ingots.

2. Heat Treatment
   Solution heat treatment at approximately 540°C for 30 minutes, followed by rapid cooling and artificial aging at 100-180°C for several hours to achieve the T6 temper.

3. CNC Machining
   CNC lathes, laser cutting, or sawing are used to produce discs with precise dimensions.

4. Surface Treatment

• Anodizing: Enhances wear resistance and appearance

• Electrophoretic Coating: Provides additional corrosion protection

• Sandblasting: Improves surface uniformity and texture
