Product Details
Brass is a metal alloy known for its low friction properties,
exceptional electrical conductivity,
and distinctive golden appearance.
This material offers good machinability, making it suitable for a
wide range of applications that
demand low friction and high electrical conductivity.
| Common Brass Materials |
| No. | Properties |
| Brass Cz121 | Brass Cz121/C360 (CNC) is a highly machinable alloy with good
tensile strength and natural corrosion resistance. Ideal for parts
that require low friction. |
| Brass C360 | Brass C360 (CNC) is highly machinable alloy with good tensile

Brass Finishing and Post-Processing
360 Brass has a shiny yellow finish that varies depending on
surface roughness.
It can be hand-polished to increase its sheen, or media blasted for
more of a matte texture.

Applications of CNC Brass Parts
1. Woodworking Industries:
CNC machining is extensively employed in the woodworking sector,
particularly for the production
of wooden furniture. This application offers significant time and
cost savings compared to manual
carving, enabling the creation of furniture with intricate
geometries that might otherwise require
the expertise of a master woodworker.
2. Lettering and Engraving Systems:
CNC machining is utilized in applications where heavy-duty material
removal is not necessary.
Instead, engraving tools are employed to mark patterns or text onto
the surface of a part.
This versatile application is used for artistic purposes or for
serializing parts.
3. Electrical Industry:
The electrical industry relies on CNC machining for a diverse range
of applications.
This includes machining component mounting holes into printed
circuit boards and creating
aluminum or copper heat sinks for heat-generating electrical
components.
CNC machining ensures precision and efficiency in the production of
crucial electrical parts.
4. Pharmaceutical Industry:
CNC machines play a crucial role in the pharmaceutical industry,
manufacturing precise equipment
used in the production of pharmaceutical products. Applications
range from extremely precise
metering pumps to ingredient-dispensing nozzles and packaging
components.
5. Food and Beverage Industry:
CNC machining is integral to the fast-moving consumer goods
industry, contributing to the
production of custom material-handling machinery. CNC-machined
parts play a crucial role in
enhancing the efficiency and precision of these machines.
Additionally, CNC machining is involved in the creation of
injection molds for food packaging,
ensuring high-quality and precisely molded packaging for food and
beverage products.

FAQ's
1. Factors Affecting CNC Machining Costs:
The cost of CNC machining a part is contingent on several factors,
including:
1. Material: Different materials come with varying costs. Machining
materials like Inconel are
pricier due to increased tool wear and slower cutting speeds
compared to more economical
options like aluminum.
2. Complexity: Parts with intricate features incur higher machining
costs. Complex surface
shapes, for example, contribute to increased expenses compared to
simpler, flat surfaces.
3. Tolerances: Tight dimensional tolerance requirements contribute
to elevated costs.
Needlessly specifying tight tolerances on non-critical features can
increase CNC machining
expenses without added value.
4. Surface Finish: Achieving mirror finishes requires specialized
tooling and strategies,
extending machining time and, subsequently, increasing costs.
5. Quantity: Low-volume production is inherently costlier per part
due to the spreading of
initial setup and programming costs over a smaller quantity.
Large-volume production offers
cost advantages as these setup costs are distributed over more
parts.
2. Tolerance Specifications for Machined Parts:
Our tolerances for machined parts are outlined below:
Local tolerances of +.005”/- .005” are applied across most
geometries in metals, while plastics
have a tolerance variation of +/- 0.010". Tolerance specifications
may vary for large parts,
especially concerning flatness after heat treatment.
For CNC parts with an "As Milled" finish, a minimum surface finish
of 125 is required.
Fabricated parts adhere to a dimensional tolerance of 0.010” and an
angular tolerance of 1°.
Tapped holes not explicitly identified as features on the quoted
CAD model may be machined to
the diameters specified in that model.
Surface treatments (e.g., anodize, bead blast, iridite, powder
coat, etc.) will not be applied unless
specifically paid for and acknowledged.
3. Dedication to Quality Assurance:
Our commitment to customer trust is reflected in our rigorous
adherence to proven quality
management principles. This commitment extends to enhancing
customer satisfaction and
continuously improving our performance and capabilities.
With decades of experience, we meet stringent regulations and
maintain PPAP compliance,
particularly in the automotive, aerospace, and medical device
industries.
These industries serve as benchmarks for the quality of all
products we manufacture.
