CNC Machining With Brass
HRC Metal Products can manufacture parts from several different materials. Our experienced machinists can manufacture aluminum machined parts, brass machined parts, bronze machined parts, copper machined parts, machined plastic parts, and steel machined parts for multiple industries and applications.
brass motorcycle parts
Brass is an outstanding choice for manufacturing motorcycle parts in CNC applications, much like its prevalence in other industrial uses. Its composition of copper and zinc endows it with exceptional workability, being notably softer than most metals. This softness enables CNC equipment to cut through the material with great efficiency, precisely carving out the intricate shapes demanded by motorcycle part designs.
Brass CNC Machining Applications
Companies choose brass to manufacture a broad range of products and components across many industries, including plumbing, automotive, filtration and more. At HRC Metal Products, our engineers and machine operators leverage decades of experience designing, testing and manufacturing the most durable, highest-performing brass components. Some examples of the items we produce include:
- Pipe and flare fittings.
- Bearings.

Benefits of Custom Machined Brass CNC Parts
Besides its superior workability and resistance against temperature and corrosion, brass offers various advantages for many CNC-machined parts applications. It’s ideal for virtually any CNC machining operation, from multi-spindle machines to milling and turning centers to Swiss screw machinery. Additional advantages of using brass in CNC machine applications include:
- Cost savings over denser metals.
- Antibacterial properties.
- High workpiece-to-tool compatibility.
- Excellent recyclability.
- Great electrical conductivity.
Corrosion resistance
Unlike other alloys, brass does not contain iron protecting it from rusting. And when alloyed with some quantities of aluminum, it will even more resistant to corrosion. The durability of parts can be enhanced while maintenance costs get decreased.
Low friction coefficient
Brass is perfect for parts like bearings, seals, and gears with its low coefficient of friction. Brass parts enable high-speed operation and tighter seals for fittings.
Excellent machinability
When it comes to a softer material with lower hardness and strength than steel alloy, brass would be the premier option. It is widely applied in CNC machining given its dimensional stability, good malleability, and durability.
Attractive appearance
The delicate appearance of the material is always in all-time demand in rapid prototyping. With its natural golden color, it is commonly used in CNC machining for aesthetic purposes, with no need for extra coating. There is not much better visually appealing than the bright golden appearance of brass for applications focus on aesthetics.
Brass Material Grades Available with Us
Brass is mainly composed of copper and zinc, also alloyed with combinations of other metals such as lead, iron, tin, and aluminum to further enhance its properties. Different brass compositions have different characteristics, extremely determining the properties you may need for your project. Therefore, it’s necessary to have a profound understanding of brass alloys. Four main brass grade materials we offer are shown below to help you determine the right one as per your design specification.
Red Brass│Brass C230
Red brass is significantly stronger than yellow brass. Brass C230 can be suited for hot and cold work. Of its excellent resistance to corrosion, and cheaper price than other copper-zinc alloys, it has been widely used for decorative items.
Free Machining Brass│Brass C360
Brass C360 is a zinc-alloyed formulation with the highest amount of lead element, so it has the highest machinability of all copper alloys. It can be ideal for parts that need strength or a polished surface finish. A thin protective patina protects C360 from rusting. Also, it can be forged and annealed.
Cartridge Brass│Brass C260
Brass C260 is a metal alloy that consists of 70% copper and 30% zinc. It is known as cartridge brass because it has been used in ammunition cartridges for a long time. This grade of copper alloy is highly ductile and is used in general cases in which all copper alloys will suffice.
Finishing Choices in Brass CNC Machining
Given its inherent properties of electrical conductivity, low friction, and corrosion resistance, CNC machined brass parts generally don’t take extra coating anymore. However, if the part is exposed to some elements or the application is cosmetic, some available surface finishes are worthwhile to consider.
Brass can be found in most cases that focus on aesthetic purposes because of its natural colors, particularly in ornament applications. A smooth and shiny surface can be achieved by polishing the brass part.

To enhance the weather resistance of the products, especially the part used for outdoor brass light fixtures, it’s often viable to employ a method – powder coating to improve their durability or to add color.

CNC Machining Brass FAQs
Is brass easy to machine?
Brass is a copper-zinc alloy that is easier to machine than aluminum. Brass is far less likely to adhere to tools than aluminum, so it can be machined faster at a lower power. Brass C360 is an alloy with the easiest machinable properties, so this is exactly why it is also referred to as free machining brass.
How do I cut and shape brass?
There are different shapes and sizes of brass, for example, brass rods, brass sheets, and brass tubing. The premise to use brass is to cut and shape it correctly.
1. Cutting brass
For small brass rods or tubing, it’s suggested that use cutting pliers or a hacksaw to cut it; For larger rods, larger cutting machines are necessary.
A handy motorized rotary is most often used to cut brass tubing, rods, and sheets. You are likely to get any shape and size you want because it’s not as hard as some metals like steel.
2. Shaping brass
What you need to do is bend and shape the brass part to meet your application requirements after cutting it. Fortunately, it’s easy to shape and bend the brass as well. For example, you can bend and shape a brass wire with a plier.
It could be a bit difficult when it comes to shaping brass sheets. But you may be assured that there are several tools to help do the job easier.
Is brass the right choice for my project?
Brass is acknowledged for its low friction coefficient, impact and corrosion resistance, extreme durability, etc. That is why it is often found in a wide variety of applications and industries. Therefore, if you are searching for a reliable and stunning material for CNC machining, brass seems to be a nice choice.
There are lots of brass grades but choosing which one is ultimately depending on the specific requirement for your projects. Still have no ideas about how to choose the right material and the machining operations? Contact us now to check out our CNC brass machining services. Our experts are here to help you to achieve a more cost-saving, efficient, and accurate process in the manufacturing of your parts with a free quote within 24h.
What should I consider about CNC machining brass?
- Use cutters with carbide inserts or carbide cutting tools – the removal rate of material and tool life will be enhanced, also the run speed of mills will be increased.
- Apply the spindle liners in the machine shop – it’s a way to protect the workpiece, device, and operators, minimize the clearance to damp vibration and reduce the bar whip at a maximum extent, also allow the machine to run at a higher speed, and guarantee the quality of turned or milled brass parts.
- Make sure the correct programming – it has a significant impact on brass CNC cutting. The right codes ensure spindle speed and operations running at the desired state.
