    CNC Brass Prototyping

    Brass is one of the most popular metal alloys for rapid prototyping, especially used for CNC machining and sheet metal fabrication. Brass is a metal alloy for which copper and zinc are primarily accounted. The proportion of the two significant elements may be correspondently changed to achieve different mechanical and electrical properties. Rapid prototyping can fully use the good properties offered by brass, such as tighter seals for fittings, and can be easily machined and joined. More importantly, it can save production costs and keep strength under high stress.

    5-Axis CNC Machining Brass

    Brass is usually considered one of the easiest materials to be machined in CNC turning or milling. Its high strength can be maintained even under some cases of extremely harsh conditions. Our 5-axis CNC machine shops have the capability of creating machined brass parts and components that are durable and cost-efficient, particularly creating tighter seals for fittings commonly applied in precision engineering for manufacturing cylinder parts or electronic hardware. The tight tolerance and complex geometry of brass parts would be easily achieved with our precision 5-axis equipment.

    One single setup helps to save setup time, fasten the lead time, and increase productivity.

    5-axis CNC machine with a versatile configuration allows for the complex geometry of brass parts.

     Workpiece can be machined in a single run, thus quality is improved while error is reduced.

    The load on the cutting tool can be reduced by the use of more rigid and shorter tools.

    Three Tips for Brass CNC Machining

    The brass high-speed CNC machining can be realized under comprehensive consideration of tools, parameters, equipment, and conditions.

    Three Tips for Brass CNC Machining

    1. 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.

    2. 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.

    3. 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.

    Our Brass Grades for CNC Machining

    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 BrassBrass C230

    Red brass is significantly stronger than yellow brass. Brass C230 can be suited for hot and cold work. It's a versatile alloy, known for its remarkable natural golden appearance and good machinability. Of its excellent resistance to corrosion, and cheaper price than other copper-zinc alloys, it has been widely used for decorative items.

    Free Machining BrassBrass 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. With its incredible machinability, the tool wear will be minimized. 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 BrassBrass 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.

    Benefits of CNC Machining in Brass

    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.

    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.

    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.

    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.

    Finishes & Post-Processing Options for Brass Machined Parts

    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.

    As Machined

    As Machined for Brass Machined PartsBrass 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.

    Hand polishing, honing, or buffing

    Hand polishing, honing, or buffing for Brass Machined Parts

    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.

    Powder coat

    Powder coat for Brass Machined Parts

    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.


    Electroplating for Brass Machined Parts

    The trick to electroplate brass is to apply the electrical current to coat an object with a thin layer of a metal material such as nickel and chrome. The deposited layer of metal material creates better properties like wear resistance or an appealing appearance that initial brass parts may lack.

    CNC Machining Brass FAQs

    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.

    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.

    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.
