C360 Free-Cutting Brass (UNS C36000) is a excellent-to-machine material that we run regularly for export customers. It has a density of 8.49 g/cm3, a tensile strength of 338 MPa and a typical hardness of HB 80. Those numbers make it the right choice for fittings and valve bodies, and a poor choice when cost or corrosion resistance matters more than mechanical performance.
On our machines we hold +/-0.01 mm on turned and milled features and reach Ra 0.4 um where the drawing calls for it. Standard lead time for C360 Free-Cutting Brass parts is 3-7 working days, including material procurement, machining and any finishing operation you specify.
C360 Free-Cutting Brass: key properties
| Property | Value |
|---|---|
| UNS / designation | C36000 |
| Density | 8.49 g/cm3 |
| Tensile strength | 338 MPa |
| Hardness | HB 80 |
| Machinability | Excellent |
| Suggested cutting speed (carbide) | 300-500 m/min |
| Relative material cost | 3 of 5 |
Machining C360 Free-Cutting Brass: what to plan for
- Dezincification in seawater
- Ammonia stress cracking
- Lead content vs RoHS
Cutting speed for C360 Free-Cutting Brass with carbide tooling sits around 300-500 m/min. Going faster burns the edge; going much slower causes rubbing and a poor surface. Air blast or flood coolant both work, but chip evacuation must be positive. If your part has thin walls or a lot of stock to remove, say so in the RFQ — we plan roughing, stress relief and finishing as separate operations when the geometry demands it.
Parts we machine in C360 Free-Cutting Brass
- Fittings
- Valve bodies
- Electrical pins
- Gears and bushings
Most C360 Free-Cutting Brass work arrives as 2D drawings with a mix of critical and non-critical features. Loosening tolerance on the non-critical ones is the fastest way to cut cost, and we will tell you which features those are before we quote.

Frequently asked questions
What is the lead time for C360 Free-Cutting Brass parts?
Standard is 3-7 working days from drawing release, assuming the material is in stock. Exotic grades and cast forms can add 5 to 10 days. Finishing such as anodizing or plating adds 3 to 5 days.
What tolerance can you hold in C360 Free-Cutting Brass?
+/-0.01 mm is routine on turned and milled features. Tighter than that is possible on specific features by grinding or lapping, but it is quoted separately because it changes the process.
Do you keep C360 Free-Cutting Brass in stock?
We hold common sizes of C360 Free-Cutting Brass and buy mill-certified stock for everything else. Material certificates are supplied with the parts on request.
Can you supply C360 Free-Cutting Brass parts with a certificate of conformity?
Yes. We issue a dimensional report, a material certificate and a certificate of conformity as standard for production orders, and full PPAP or AS9102 paperwork when the programme requires it.
