How We Make Your Brass Parts
We use many different methods to make your brass parts perfect:
CNC Milling
With CNC milling brass, we cut away brass material to create your part. Our machines can move in multiple directions at once to make complex shapes.
CNC Turning
For round parts like rods, tubes, or anything that needs to be cylindrical, we use CNC turning.
Swiss Machining
For tiny, super-precise brass parts, we use Swiss machining which is perfect for:
Small medical parts
Watch components
Small electrical connectors
Delicate instrument parts
Types of Brass for CNC Machining
There are many kinds of brass. Each one is good for different jobs. Let’s look at the best ones:
Free-Cutting Brass (C360)
Cartridge Brass (C260)
Naval Brass (C464)
Eco Brass (C693)
Red Brass (C230)
Free-Cutting Brass (C360)
C360 is the best brass for most CNC jobs. It has:
- 60-63% copper
- 35% zinc
- 3% lead
This brass cuts the best of all. Tools last longer when cutting C360. It is the top pick for:
- Gears
- Valves
- Small parts
Cartridge Brass (C260)
C260 has:
- 70% copper
- 30% zinc
This brass bends well without breaking. It is good for:
- Bullet cases
- Pretty parts
- Parts that need to bend
Naval Brass (C464)
This brass works great near salt water:
- 60% copper
- 39% zinc
- 1% tin
The tin helps it not rust in water. Use it for:
- Boat parts
- Water pumps
- Parts that get wet
Eco Brass (C693)
This is a green brass with no lead:
- Made with copper, zinc, and silicon
- Safe for water and food
- Meets rules for health
It is good for:
- Water pipes
- Food machines
- Medical parts
Red Brass (C230)
This has the most copper:
- 85% copper
- 15% zinc
It looks more red than other brass. Use it for:
- Hot water pipes
- Heat parts
- Pretty red-gold parts
