What is custom brass CNC machining?

We produce brass parts to your specific design—your dimensions, tolerances, material, and finish. Every job is unique and built to your requirements.

What brass grades can you machine for custom orders?

C36000 (Free-Cutting Brass), C37700, and C38000. C36000 is the most commonly used grade.

What is the machinability of brass?

C36000 has a machinability rating of 100%, the benchmark for all other metals. Its lead content improves chip breakage and reduces tool wear.

Is there a minimum order quantity?

No. We machine single prototypes and high-volume production runs with the same quality standards.

What is the typical lead time for custom brass parts?

Prototypes in 3-5 business days. Production orders in 10-20 business days.

Yes, brass can be nickel, chrome, gold, or tin plated. Plating provides corrosion protection, decorative finish, or improved electrical conductivity.

Custom Brass

Custom brass CNC machining is the precision processing of brass alloys manufactured to customer-defined specifications. Brass is a copper-zinc alloy that offers excellent machinability, good corrosion resistance, electrical conductivity, and attractive appearance. The most commonly machined brass grade is C36000, which has a machinability rating of 100%.

Brass's high machinability comes from its composition: lead addition creates chip-breaking characteristics that reduce tool wear and enable high cutting speeds. Tolerances are held to ±0.01-0.02mm standard. Every custom order is unique—your design, your tolerances, your material, your finish.
