Our Brass Grades for CNC Machining
At Machiningtoday, we take pride in the quality of our work. That’s why we only use the best materials available, including brass. Brass is an excellent choice for CNC machining because it is strong and durable yet easy to work with. We offer a variety of brass grades to choose from, each with its unique set of properties.
Red Brass│Brass C230
Red brass, or Brass C230 as it is sometimes called, is an alloy of copper and zinc. It has a reddish color.
Red brass is usually easy to machine, making it a popular choice for various applications.
It is generally suitable for the plumbing and electrical applications because it is resistant to corrosion.
Cartridge Brass│Brass C260
Cartridge brass, also known as UNS C26000 or brass C260, is a type of phosphor bronze that contains approximately 60% copper and 40% zinc.
This slightly higher zinc content gives it better machinability than other types of brass.
Cartridge brass is often suitable for making cartridge cases, ammunition components, and other parts that require strength and durability.
It is also suitable for decorative purposes, such as jewelry or architectural accents.
Free Machining Brass│Brass C360
Free machining brass is a type of brass that contains small amounts of lead.
Lead lowers the resistance of the metal to cold work deformation and increases its machinability.
That means free machined brass can be cut and shaped more quickly than other types of brass.
C360 (also known as cartridge brass) is the most common grade of free machining brass. It contains 27% zinc and 3% lead.
Free machined brass also has good corrosion resistance, making it ideal for applications where the finished product will be exposed to the elements.
C360 is commonly used in plumbing fixtures, electric switches, gears, and hardware.
High Leaded Brass│Brass C353
High leaded brass C353 is a yellowish alloy of brass with high lead content. It is easy to machine and has good hot-working properties.
Plus, high lead brass has good solderability and can be combined using various methods, including brazing and soldering.
In addition, it has excellent wear resistance and galling resistance.
These properties make it ideal for use in applications where wear and galling are a concern, such as gears and bearings.
However, the high lead content also makes C353 less corrosion resistant than other types of brass.
As a result, it is not recommended for use in environments where corrosion is a concern.
How do we control the quality of CNC brass machining?
Methods used to ensure machined brass components’ quality include in-process and final inspection procedures. In-process inspection is conducted at each machining operation to ensure that dimensions are within tolerance and that the surface finish is acceptable.
After all machining operations are complete, the final inspection is conducted and includes dimensional, visual, and functional testing. Dimensional inspection verifies that all dimensions are within specified tolerances, while visual inspection checks for cosmetic defects such as scratches or dents.
Finally, functional testing is conducted to verify that the component meets all performance requirements. By implementing both in-process and final inspection procedures, manufacturers can ensure that machined brass components meet all quality requirements.
surface finishes for CNC brass
To protect brass parts from the elements,brass surface finishes Electroless Nickel Plating, polishing, passivation. Finally, choosing a suitable surface finish ensures that your brass parts stand up to the elements for years.
Electroless Nickel Plating
Electroless nickel plating is one option that can provide superior protection against corrosion.
This process involves depositing a nickel layer on the brass surface, which acts as a barrier to oxygen and moisture. It will protect the brass parts from corrosion.
Electropolishing is another option that can help extend copper parts’ life by reducing the amount of surface area exposed to the environment.
This process removes impurities from the brass surface, resulting in a smoother finish that is more resistant to corrosion.
Passivation is another way to protect brass parts from corrosion.
This process involves treating the brass surface with an acidic solution, which helps to remove impurities and create a protective oxide film.

Brass Machining FAQs
We’ve learned that there’s a lot of mixed information online about machining brass. So here are some of the most common questions we answer for our customers. It helps you quickly understand CNC machining brass.
Machining brass parts
The process of processing brass parts is as follows:
Choosing the proper grade of brass
When machining brass, choosing a suitable grade of material is essential.
For instance, free machining brass contains high levels of lead and sulfur, which makes it easier to machine but also reduces its strength and corrosion resistance.
So choosing the correct grade can improve the excellent corrosion resistance of copper.
Free Machined Brass C36000 is the most versatile and commonly used copper alloy. Brass C260 Brass C260, or cartridge brass, contains 70 percent copper and 30 percent zinc.
Free machining brass, copper zinc alloys has the highest machinability of all copper alloys and is the standard against which all the others are compared.
Conversely, high-strength brass has lower levels of lead and sulfur, making it more difficult to machine but providing greater strength and durability.
The brass alloy has high elasticity and is considered the most general purpose of all brass alloys.
Different brass alloys naturally show up in different colors. Numerous brass alloys are used in CNC machining, with a wide variety of properties, and they are helpful for distinct industries.
Choose the correct process.
When machining copper parts, it’s essential to choose the proper process to ensure accuracy and avoid damage to the material.
One standard machining process for brass is turning, which involves cutting the material to create the desired shape.
Turning is well suited for creating cylindrical shapes but can also be used to produce other simple shapes such as cones and spheres.
Another machining process that can for brass is milling.
It involves using a rotating cutter to remove material from the surface of the brass piece. Milling can be used to create complex shapes and patterns, making it ideal for creating intricate parts.
When choosing a machining process for copper parts, it’s essential to consider the required tolerance, finish, and complexity of the desired shape.
We can choose the most suitable process according to our needs.

Advantages of brass CNC machining
CNC machining brass has many advantages over other materials.For example, brass is solid and durable yet still easy to machine.
It also has excellent electrical and thermal conductivity, making it well suited for applications where those properties are essential.
In addition, brass machining and turning parts have a high heat and corrosion resistance!
Low friction coefficient— Brass is a mechanically more robust and lower-friction metal, offering better wear resistance.
What's the difference between brass, bronze, and copper?
All three of these metals have unique benefits and drawbacks that need to be considered.
Brass is a metal alloy in metals. Brass alloy is the most prevalent metal for machining due to its machinability, corrosion resistance, and strength.
However, it is also the most expensive of the three metals.
Bronze is less expensive than brass but is more difficult to machine.
Copper is the most accessible metal to machines but is also the most susceptible to corrosion.
Is brass easier to mill than aluminum?
Brass is also easier to mill than aluminum, making it a popular choice for machining.
Why does brass turn green over time?
This phenomenon, known as brass patina, results from a chemical reaction between the brass and oxygen in the air.
As the brass reacts with oxygen, it forms a thin layer of greenish-black copper oxide on the surface of the metal.
The copper oxide not only changes the color of the brass but also helps protect the metal from further corrosion.
