Casting Processes Suitable for Brass Components

Die Casting

Die casting enables the production of thin-wall and complex geometries under high pressure, delivering exceptional dimensional accuracy and consistency.
It is ideal for high-volume manufacturing of precision metal components with strict tolerance requirements.

Gravity Casting

Gravity casting uses reusable metal molds and gravity-fed pouring to achieve improved density and stable dimensions.
This process suits medium- to large-sized structural parts, offering reduced internal defects and lower tooling costs than high-pressure die casting.

Brass sand casting pouring molten metal into sand mold

Sand Casting

Sand casting forms parts by pouring molten metal into expendable sand molds, allowing greater freedom in shape and section thickness.
It is suitable for prototypes, low-volume production, and large structural components where cost efficiency and flexible design are priorities.

Brass Applications by Industry

Building Hardware

Brass castings are widely used in building hardware where corrosion resistance, machinability, and visual appearance all matter. Common applications include door handles, hinges, locks, railing fittings, decorative trims, and window or door hardware. For both decorative and functional components, brass offers a stable finish and good long-term performance in indoor and semi-exposed environments.

Electronics

Brass offers excellent electrical conductivity, dimensional stability, and anti-sparking performance, making it ideal for bus bars, grounding terminals, connectors, and switchgear parts.
It ensures reliable power transfer in consumer electronics, industrial control systems, and high-voltage equipment.

Fluid & Industrial Components

Brass is preferred for pump bodies, valve seats, precision fittings, and threaded connectors, due to its stable machinability and resistance to corrosion in water, oils, and non-aggressive chemicals.
Common applications include hydraulic valve assemblies, plumbing fittings, compressor components, and gas or water control systems.

Power & Energy Connectors

Brass is commonly used for electrical lugs, connector blocks, terminal components, and grounding hardware because it combines good conductivity, corrosion resistance, and reliable machinability. These properties make it suitable for power distribution equipment, switchgear accessories, and industrial connection systems.

Consumer & Premium Goods

Due to its premium finish, durability, and friction resistance, brass is commonly used in faucets, sanitary fittings, luxury hardware, musical instruments, zippers, and precision hand tools.
It combines aesthetics with reliable wear performance.

What Is Brass Casting?

Brass casting is a manufacturing method in which molten brass is poured into a mold to form parts with the required shape. It is suitable for producing a wide range of custom brass components and is commonly used for valves, fittings, housings, and other parts that require good corrosion resistance, machinability, and surface quality.

Quality Assurance for Brass Castings

Quality control covers multiple key stages, from material verification and drawing review to final inspection before shipment, helping improve dimensional consistency, surface quality, and production stability.

Material Verification

We verify incoming material grades and specifications to support stable casting quality from the start.

Drawing and Process Review

We review part drawings and process requirements before production to identify key control points early.

In-Process Control

Key production steps are monitored during casting to help reduce variation and improve consistency.

Dimensional Inspection

Critical dimensions and functional features are checked to support fit, assembly, and application needs.

Surface and Visual Inspection

Visible surfaces and finishing conditions are inspected before delivery to improve overall part consistency.

Final Inspection Before Shipment

A final inspection is carried out before shipment to confirm order requirements and delivery consistency.

FAQ – Frequently Asked Questions

Alloy selection depends on strength, corrosion resistance, machinability, and application environment. H59 / H62 are widely used for general structural parts, H65 / H68 offer higher strength and better corrosion resistance, while C36000 is preferred for high-machinability components. Share your drawings and we can recommend the most suitable grade.
Yes. We offer complete DFM evaluation for brass casting, including wall-thickness optimization, draft angle suggestions, gating design review, and shrinkage/porosity prevention analysis. This helps ensure stable casting quality and reduces machining costs.
For gravity casting, brass alloys typically support 2.5–4.0 mm minimum wall thickness. Sand casting usually requires 4–6 mm. The final value depends on geometry and alloy flow behavior.
As-cast brass parts generally meet ISO 8062-3 CT7–CT9. With in-house CNC machining, critical features can reach ±0.10–0.15 mm accuracy and Ra 1.6–3.2 µm surface finish.
To provide an accurate quote, please include:
  • 2D/3D drawings (STEP, IGES, PDF)
  • Alloy grade (H59 / H62 / H65 / H68)
  • Annual and batch quantity
  • Critical tolerances & machining requirements
  • Surface treatment (polishing, plating, passivation, etc.)
If anything is unclear, simply send the drawing—we will assist with feasibility.
Yes. We support prototype quantities (5–30 pcs), small-batch production, and mass manufacturing. Sand casting is suitable for prototypes and complex shapes, while gravity casting provides better dimensional stability and improved surface quality.
