Brass Stamping and Brass Stamped Parts – Precision Pressed Components by A1 Metallics
A1 Metallics is a premier manufacturer of brass stamped parts and brass stampings for electrical, electronics, automotive, plumbing, and industrial applications. Leveraging state-of-the-art progressive die stamping, compound die stamping, and deep drawing presses, we produce high-volume brass stamped components with consistent quality and tight dimensional tolerances.
Our brass stamping capabilities cater to US, European, and global customers seeking cost-effective alternatives to machined brass parts, combining the excellent machinability and corrosion resistance of brass with the speed and economy of metal stamping.
Brass Stamped Electrical Parts
Brass is widely used in electrical stamped components due to its excellent electrical conductivity, easy solderability, and corrosion resistance. A1 Metallics produces brass stamped contacts, brass terminals, brass connector pins, brass bus bar segments, brass earth clips, and brass switchgear parts. Our brass electrical stampings meet IEC and UL standards for conductivity and contact resistance.
Brass Stamped Automotive Parts
The automotive industry relies on brass stampings for precision small parts where corrosion resistance and conductivity are essential. We manufacture brass stamped automotive connectors, brass retaining clips, brass springs, brass shims, and brass sensor components. Our automotive brass stampings are produced to TS 16949-aligned quality standards with PPAP documentation available.
Brass Deep Drawn Parts
Deep drawing of brass produces seamless hollow shapes such as brass cups, brass shells, brass caps, and brass cartridge cases. A1 Metallics deep draws brass up to 6mm thickness with draw ratios up to 2.5:1. Brass deep drawn parts are used in valve bodies, instrument housings, audio connectors, and ammunition components.
Brass Progressive Die Stamped Parts
Progressive die stamping is ideal for high-volume brass components combining multiple operations (blanking, forming, piercing, coining) in a single die. A1 Metallics’ progressive stamping presses range from 25 to 400 tonnes, handling brass strip from 0.1mm to 6mm thickness. We produce brass progressively stamped parts at speeds up to 800 strokes/minute for large orders.
Brass Stamped Plumbing and Hardware Parts
Brass stamping for plumbing includes escutcheon plates, brass valves seats, brass packing rings, brass flange plates, and brass pipe brackets. Hardware stampings include brass door plates, brass hinges, brass corner brackets, and decorative brass pressed panels for furniture and cabinetry.

Frequently Asked Questions – Brass Stamping and Brass Stamped Parts
Q1: What brass alloys are best for stamping?
Cartridge Brass (C26000 / CuZn30) is the gold standard for deep drawing due to its high ductility. Yellow Brass (C27000) and Muntz Metal (C28000) are used for general hardware stampings. Naval Brass is preferred for marine environment stampings.
Q2: What is the minimum order quantity for brass stampings?
For standard parts with existing dies, MOQ is 5,000–10,000 pieces. For custom brass stampings requiring new tooling, MOQ starts at 10,000 pieces to amortize tooling costs. Samples (50–200 pieces) are available using soft tooling.
Q3: Can brass stampings replace machined brass parts?
In many cases, yes. Brass stampings are significantly more economical for flat and shallow-formed parts. Complex threads and precision bores still require machining. A1 Metallics can advise whether stamping, turning, or a hybrid approach best suits your application.
Q4: Are your brass stamped parts RoHS compliant?
Yes. We supply RoHS-compliant brass stampings using alloys that contain no restricted substances above EU threshold limits. Lead-free brass options (C69300, C87850) are also available for applications requiring strict lead-free compliance.
Q5: What surface finishes can you apply to brass stamped parts?
We offer barrel tumbling (deburring), vibratory finishing, tin plating, nickel plating, electroless nickel, gold flash plating, chrome plating, and bright brass lacquering. Plating is performed by certified sub-contractors to ASTM B545, B689, and related standards.
Q6: What documentation do you provide with brass stampings for the USA market?
We provide: Certificate of Conformance, Material Test Reports (ASTM-compliant), RoHS Declaration of Conformity, dimensional inspection reports, and packing lists with HS codes. We can also accommodate customer-specific quality documentation requirements.
