Several factors affect the final cost. The specific brass alloy chosen impacts material price. Part complexity – including intricate features, tight tolerances, and required surface finishes – influences machining time. Order quantity also plays a significant role, with higher volumes typically allowing for lower per-part costs due to setup efficiencies. Finally, any required secondary operations like plating or polishing will add to the overall cost.
Brass's high machinability translates directly into several project benefits: faster production cycle times, potentially lower machining costs due to reduced time and tool wear, the ability to hold tighter tolerances more easily, and achieving exceptionally smooth surface finishes directly off the machine. This makes it highly efficient for both prototyping and high-volume production runs where speed and cost-effectiveness are important.
Brass readily accepts excellent, smooth surface finishes directly from the machining process due to its machinability. It can also be easily polished to a high, bright luster. Various plating options (like nickel, chrome, or tin) are also commonly applied to brass parts for enhanced durability, corrosion resistance, or specific aesthetic requirements.
Delivering high-quality, consistent brass components is a top priority at Spex. While brass is generally easier to machine than many other metals, precision is still crucial. Our quality system, built on our ISO 9001:2015 certification, ensures careful checks during production for dimensional accuracy and adherence to specifications. These same quality standards apply from prototype to high-volume production runs.
To provide the most accurate quote, please share detailed part drawings or CAD models, specify the exact brass alloy required (e.g., C360, C260), required tolerances, desired quantity, any critical features, and details on necessary finishing operations (like polishing, plating, or engraving). The more detail provided, the better we can tailor a precise and competitive quote.
