Brass Manufacturing and Custom Parts
A machinable copper alloy used for connectors, inserts, fittings, and decorative components.
- Good machinability
- Conductive
- Corrosion resistant
Material overview
A highly machinable copper alloy family for connectors and fittings.
Brass is often selected for turned connectors, threaded inserts, fittings, terminals, bushings and decorative components because it machines cleanly and can offer useful conductivity, corrosion resistance and appearance.
The correct brass grade depends on machinability, regulatory requirements, mechanical load, plating needs and contact function. Kewei reviews threads, sealing faces, knurls, electrical contact areas and cosmetic expectations before confirming the manufacturing route.
Key properties
Performance characteristics translated into manufacturing decisions.
Conductive behavior
Useful for selected electrical terminals and contact components when alloy and plating are specified.
Decorative appearance
Can be left as a brass appearance or paired with nickel, chrome, polishing or brushing after review.
Insert compatibility
Commonly used for threaded inserts and overmolded hardware when knurl and retention geometry are designed correctly.
Suitable processes

Threaded inserts
Fluid fittings
Electrical terminals
Connector bodies
Decorative knobs
Bushings and spacers
Design considerations
Control the features that affect function and process stability.
G 01
Specify thread standard, thread depth and gauge requirements.
G 02
Define knurl geometry and pull-out requirements for inserts.
G 03
Call out plating thickness, masking and post-plate inspection for fitted features.
G 04
Identify contact surfaces where conductivity or cleanliness matters.
Limitations
Requirements that need engineering review.
- Brass is heavier and softer than many steels, so loaded wear surfaces need review.
- Lead content or compliance restrictions may limit alloy choices.
- Plating adds thickness and can affect threads, bores and sealing faces.
- Bare brass can tarnish unless finish and packaging expectations are defined.

FAQ
Brass questions from engineering and sourcing teams.
Why is brass common for threaded inserts?
Brass machines well, supports accurate threads, and can be knurled or shaped for retention in molded plastic parts.
Can brass parts be nickel or chrome plated?
Yes, brass is commonly reviewed for nickel or chrome plating. Plating thickness and masking must be considered for threads and fitted features.
Does brass stay bright without finishing?
Bare brass can tarnish over time. Polishing, plating, coating, packaging and handling requirements should be defined when appearance matters.
