CNC (Computer Numerical Control) machined brass parts are widely used in the automotive industry, mainly taking advantage of brass' good mechanical properties, electrical conductivity, corrosion resistance and easy processing. Here are some specific application examples:

Connectors:
CNC machined brass connectors are used in automotive electrical systems to ensure stable electrical connections, suitable for battery terminals, sensor connectors, etc.

Fuel system components:
Precision parts in fuel injectors, such as nozzles and filter elements, often use CNC brass parts because they require high-precision processing and good corrosion resistance.

Radiator parts:
CNC machined brass radiator parts can help dissipate heat and keep the engine at a suitable operating temperature.

Braking system components:
Certain parts of the braking system, such as adjusting nuts and gaskets in brakes, may be made of brass because they require corrosion resistance and good mechanical properties.

Air conditioning system components:
Joints, valve bodies and other connecting parts in air conditioning systems may be machined with CNC brass because they need to be resistant to refrigerants and leak-proof.

Sensor components:
Sensor housings and connecting parts often use brass materials because they require precise dimensions and good conductivity.

Lubrication system parts:
Certain valves and regulators in lubrication systems may use CNC brass parts because they require oil and wear resistance.

Fasteners:
CNC machined brass nuts, bolts, and washers are used in various automotive assemblies because they do not rust and are easily machined into specific shapes and sizes.

Emission control system parts:
Certain parts in catalytic converters and oxygen sensors used to reduce emissions may use brass materials because they need to withstand high temperatures and chemical corrosion.

Interior trim parts:
Interior trim parts such as emblems, buttons, and decorative strips in certain high-end cars may use CNC brass machining to provide unique visual effects and tactile effects.
CNC machining technology allows the production of precise, complex, and consistent brass parts, which is essential to meet the high standards and performance requirements of the automotive industry. As automotive technology develops, the application of CNC brass parts is likely to expand further.
