Many brass parts can be made in more than one way. The best choice depends on volume, shape, strength requirements and tolerance. Understanding the trade-offs helps you ask the right question when you request a quote.
| Process | Best for | Strengths | Watch-outs |
|---|---|---|---|
| Turning (CNC / multi-spindle) | Round parts, threads, small precision components | Tight tolerances, excellent finish, no tooling cost | Material waste from bar; slower for large bodies |
| Hot forging | Valve bodies, fittings, flanges | Dense grain, pressure-tight, efficient material use | Die cost; needs machining for threads and faces |
| Casting (sand / gravity die) | Complex shapes, low to medium volumes | Lower tooling cost, intricate geometry | Possible porosity; rougher surface |
Rules of thumb
- If the part holds pressure — water, gas, hydraulic — forging is generally preferred over casting.
- If volumes are small or the shape is mostly cylindrical, turning from bar avoids tooling cost altogether.
- If volumes are high and the shape is closer to the final form, forging then machining usually gives the lowest piece price.
- If the geometry is intricate and pressure is not critical, casting may be the economical route.
Many parts use more than one process
A valve body is typically forged, then machined to cut threads and sealing faces, then plated. Describing the function of the part in your RFQ lets us recommend the most sensible route.
