Advantages
Excellent machinability, good surface finish, useful thermal/electrical conductivity and ready plating. C36000 is a common machinability reference material.
Discuss the machined feature and the alloy requirement together
For a brass thread, contact or turned component, tell Aria which fits and surfaces matter and whether a particular alloy or lead content is required. We help you review those requirements with the machining and inspection scope. Free-cutting and lead-free alloy choices should be identified explicitly rather than assumed from “brass.”
Material options
| Property | Details |
|---|---|
| Colors | Golden metallic |
| Special properties | Lead aids machining; specify a suitable lead-free alloy, such as C27450 or C69300, where required. |
Detailed values describe C36000 (CW603N) free-cutting brass, O60 / H02 / H04 range. Family ranges are broader selection references and may include different grades or reinforcement levels. Confirm the selected grade, condition and test method for your part. Melting temperature is not a working-temperature limit; use the mill certificate for the specified alloy and temper.
