Brass Stamping Parts — precision metal stamping Components for Connectors & Hardware
Brass stamping produces dimensionally precise, corrosion-resistant metal components for electrical connectors, plumbing fittings, decorative hardware, and precision instruments. As an experienced brass metal stamping manufacturer, we stamp a full range of copper-zinc alloys to produce parts that balance conductivity, formability, strength, and cost — for customers in automotive, electronics stamping components, plumbing, telecommunications, and consumer goods industries.
Brass is one of the most versatile stamping materials: its moderate electrical conductivity (27–44% IACS), excellent machinability, natural corrosion resistance, and attractive gold-like appearance make it the material of choice for connector housings, terminals, valve bodies, decorative parts, and precision mechanical components.
Brass Alloys We Stamp
We stock and stamp a wide range of brass alloys to match your specific mechanical, electrical, and environmental requirements:
- C26000 (Cartridge Brass, 70/30) — the most commonly stamped brass alloy; excellent formability for deep drawing and complex progressive die work. Tensile strength 525 MPa, 37% IACS conductivity. Widely used for terminals, cartridge cases, and precision components.
- C27000 (Yellow Brass, 65/35) — slightly higher zinc content than C26000 for improved machinability; used for screw machine products, nuts, and fittings with secondary machining operations.
- C22000 (Commercial Bronze, 90/10) — higher copper content for better conductivity (44% IACS) and deeper red-gold color; used for decorative hardware, costume jewelry components, and electrical contacts.
- C36000 (Free-Cutting Brass) — best machinability of all copper alloys; chosen when stamped parts require significant secondary turning, milling, or threading operations.
- C28000 (Muntz Metal, 60/40) — most cost-effective brass for large, simple stampings and hot forgings; used for architectural hardware and valve bodies.
- C17500 (Beryllium-Copper-Cobalt) — ultra-high strength brass-family alloy for precision spring contacts and aerospace connectors.
Benefits of Brass Stamped Parts
- Excellent formability — C26000 can be deep-drawn to high draw ratios without intermediate annealing, enabling complex geometries in a single progressive die
- Corrosion resistance — natural resistance to atmospheric corrosion; can be lacquered, plated, or passivated for enhanced protection
- Moderate conductivity — 27–44% IACS suitable for connector housings, switch contacts, and low-current terminals
- Machinability — best machinability among copper alloys, ideal for parts requiring secondary turning or threading
- Attractive appearance — natural gold-like finish suitable for decorative hardware without additional plating
- Cost-effective — 30–40% lower material cost than pure copper while maintaining good conductivity and formability
- Tight tolerances — progressive die stamping achieves ±0.01 mm on critical dimensions
- Recyclability — 100% recyclable; brass scrap commands premium prices
