Comparing Aluminum Tooling Plate - ATP-5 & Mic6

Time to Read: 0 m 0s

ATP-5 and Mic 6 are both popular aluminum tooling plate materials used in various industries for their excellent dimensional stability characteristics and machining properties. While they share some similarities, they also have a few key differences. Let's compare ATP-5 and Mic6 tooling plates regarding their aluminum alloy composition, characteristics, weight differences, and typical applications.

Aluminum Tooling Plate ATP-5 & Mic6 Composition

ATP-5 Aluminum Tooling Plate

ATP-5 is produced in a Vertical DC Casting method, specifically in high-strength aluminum alloy AA 5083. The main alloying element in AA 5083 is magnesium, resulting in a product with higher mechanical properties and superior corrosion resistance characteristics.

Mic6 Aluminum Tooling Plate

Mic6 is produced in a Horizontal Casting method manufactured in a 7000 Series Aluminum Alloy, of which the primary alloying element is zinc. This casting process and alloy combination results in slightly lower mechanical properties and lower levels of corrosion resistance.  

ATP-5 & Mic6 Aluminum Tooling Plate Comparative Characteristics

Both aluminum tooling plate ATP-5 and Mic6 provide exceptional benefits for their respective applications. ATP-5 and Mic6 aluminum tooling plate advantages include:
  • Dimensional Stability: Both ATP-5 and Mic6 offer excellent dimensional stability, which means they are resistant to distortion and maintain their flatness during typical machining processes. This stability is crucial in applications where precise tolerances and flatness are required in finished machine parts.
  • Machinability: ATP-5 and Mic6 are known for their exceptional machinability. They are easy to work with and can be milled, drilled, and tapped with relative ease. Their uniform microstructure and fine grain size contribute to their machining properties.
  • Flatness & Thickness Tolerances: Both ATP-5 and Mic6 offer exceptional thickness and flatness tolerances well established in the tooling plate industry.
  • Weldability: Both ATP-5 and Mic6 are weldable, allowing for the fabrication of complex structures and assemblies. However, it's worth noting that certain precautions should be taken during the welding process to prevent distortion or damage to the material.

ATP-5 & Mic6 Aluminum Tooling Plate Applications

Both ATP-5 and Mic6 are used in a diverse range of applications, including all forms of tooling and fixtures for:
  • Manufacturing
  • Prototype parts
  • Machine components
  • Critical dimensional parts in scientific equipment
  • Molds
  • Aluminum parts requiring critical dimensional tolerances
  • Optical equipment
  • Vacuum chucks
  • Heat sinks
With higher mechanical properties and corrosion resistance, ATP-5 provides premium thread formation in applications where threaded fasteners are required and overall higher strength levels are needed. Standard weight comparisons, as a magnesium alloy, ATP-5 weight will be 5% less than the zinc alloy used with the Mic6.

Premium Aluminum Tooling Plate ATP-5 & Mic6

Both ATP-5 and Mic6 are valuable tooling plate materials with their own set of advantages. ATP-5 offers higher strength and weight savings. Mic6 has been recognized for its ability to maintain flatness, which is the most critical application component. The choice between the two depends on the specific requirements of the application, such as the need for superior mechanical properties or precise flatness.
