What Types of Brass and Aluminum are Suitable for CNC Turning and Milling?

When selecting brass and aluminum for CNC turning and milling, it’s important to consider the specific properties of each alloy and how they align with your project requirements, such as machinability, strength, 耐食性, and intended application. Here are some commonly used brass and aluminum alloys for CNC machining:

Brass Alloys

C360 (Free-Cutting Brass):

Properties: High machinability, good strength, 耐食性, and excellent wear resistance.
アプリケーション: Precision components, fittings, バルブ, and various decorative parts.

C385 (Architectural Bronze):

Properties: Good machinability, excellent corrosion resistance, and good mechanical properties.
アプリケーション: Hardware, architectural applications, and decorative components.

C464 (Naval Brass):

Properties: Good strength, excellent corrosion resistance (especially in marine environments), and good wear resistance.
アプリケーション: Marine hardware, propeller shafts, and other maritime components.

Aluminum Alloys

6061 Aluminum:

Properties: Excellent machinability, good strength, good corrosion resistance, and good weldability.
アプリケーション: Structural components, automotive parts, and aerospace applications.

7075 Aluminum:

Properties: High strength, good fatigue resistance, and good machinability, but lower corrosion resistance compared to 6061.
アプリケーション: Aerospace and military applications, high-stress components.

2024 Aluminum:

Properties: High strength, good fatigue resistance, and good machinability, but poor corrosion resistance.
アプリケーション: Aerospace structures, military applications, and high-performance components.

5083 Aluminum:

Properties: Excellent corrosion resistance, good weldability, and moderate strength.
アプリケーション: Marine applications, pressure vessels, and transportation equipment.

5052 Aluminum:

Properties: Good formability, good corrosion resistance, and moderate strength.
アプリケーション: Sheet metal work, marine applications, and transportation industry.

Selection Criteria
When choosing the right alloy, consider the following factors:

Machinability: Ease of cutting, shaping, and drilling.
Strength: Required mechanical strength for the application.
Corrosion Resistance: Need for resistance to environmental factors such as moisture, chemicals, or saltwater.
Finish Quality: Desired surface finish and whether post-machining treatments are necessary.
Cost: Budget constraints and material cost.
These alloys are commonly used in CNC turning and milling due to their favorable properties for machining and the wide range of applications they can serve.
