Brass C36000

Introduction to Brass C36000

Brass C36000, also known as Free-Cutting Brass, is one of the most widely used copper alloys due to its excellent machinability and cost-effectiveness. It primarily comprises copper, zinc, and a small amount of lead, which enhances its cutting properties and allows for high-speed machining. Brass C36000 offers superior machinability compared to other brass alloys and is ideal for precision CNC machining. It is a top choice for industries requiring excellent machinability, reasonable strength, and good corrosion resistance. For precision machining, Brass C36000 is a preferred material due to its ability to easily be shaped and cut.

Brass C36000 is commonly used in CNC machined parts such as fittings, connectors, valves, and bushings. Its exceptional machinability makes it a go-to material in the automotive, electrical, and plumbing industries, where performance and cost-effectiveness are essential.

Key Characteristics of Brass C36000

Exceptional Machinability

Brass C36000 is known as one of the most machinable metals. Its lead content significantly reduces friction during cutting, allowing for high-speed machining with minimal tool wear. This makes it ideal for mass production of small and complex parts.

Good Strength and Durability

While Brass C36000 has excellent machinability, it also offers moderate strength, making it ideal for applications that need both durability and ease of machining. It is commonly used in components that need to withstand moderate mechanical stress.

Corrosion Resistance

Brass C36000 provides decent corrosion resistance, especially in atmospheric and freshwater environments. However, it is not as resistant to harsh chemical environments or seawater as other alloys, such as C715 or C655.

Good Electrical Conductivity

With a high copper content, Brass C36000 offers good electrical conductivity, making it suitable for components like electrical connectors and terminals, where efficient electrical performance is critical.

Aesthetic Appeal

Brass C36000 has a bright, gold-like appearance, making it ideal for decorative applications. It is often used in hardware, fittings, and fixtures requiring functional and aesthetic properties.

CNC Machining Challenges and Solutions for Brass C36000

Machining Challenges

• Chip Formation Brass C36000 produces short chips during machining, which can be helpful for machining efficiency but may cause issues if not handled correctly.

  Solution: Use chip breakers and ensure proper coolant application to clear chips efficiently and avoid buildup.

• Tool Wear Although Brass C36000 has excellent machinability, high-speed operations can still lead to tool wear, particularly in continuous cutting applications.

  Solution: Use high-quality carbide or ceramic tools to extend tool life and reduce wear during machining.

• Surface Finish Quality Achieving a smooth surface finish can sometimes be difficult due to the alloy's tendency to form burrs during machining.

  Solution: Use sharp tools, high-speed cutting, and ensure sufficient lubrication for smooth finishes.

• Work Hardening Brass C36000 can experience work hardening, especially when cutting too fast or with dull tools.

  Solution: Maintain moderate cutting speeds, use sharp tools, and apply coolant to prevent work hardening and preserve the material's integrity.
