Brass Sheet Metal Components We Manufacture

Brass Stampings and Blanks

High-speed blanking and piercing of brass sheet into discs, washers, contacts, terminals, and custom blanks. Tolerances to ±0.05 mm on blanked profiles in 0.3 mm to 3 mm brass sheet.

Brass Deep-Drawn Shells and Cups

Multi-stage deep drawing of brass into cups, cartridges, cylinders, and housings. Brass (cartridge brass C26000/CZ106) is the classic deep-drawing alloy used in ammunition, fuse bodies, and instrument housings.

Brass Electrical Contacts and Terminals

Stamped and formed brass terminals, connector contacts, bus bar tabs, and spring contacts for electrical and electronics applications. Supplied bright, nickel-plated, tin-plated, or silver-plated.

Brass Brackets, Clips, and Mounting Hardware

Custom formed brass brackets, spring clips, earth clamps, P-clips, and mounting plates for panel boards, switchgear, and instrument cabinets.

Brass Enclosures and Boxes

Fabricated brass enclosures, junction boxes, and instrument housings formed from laser-cut and press-bent brass sheet, with welded or riveted seams as required.

Brass Grilles and Perforated Sheets

Decorative and functional perforated brass grilles, screens, and mesh panels for HVAC, architectural, and acoustic applications. Available in custom hole patterns and finishes.

Frequently Asked Questions — Brass Sheet Metal Parts

Q1: Which brass alloy is best for deep drawing?

Cartridge brass (C26000 / CZ106, 70% Cu–30% Zn) is the premier alloy for deep drawing, offering excellent cold ductility, uniform elongation of 55–65%, and consistent work-hardening that prevents tearing. It allows draw ratios up to 2.2:1 in a single stage. For less demanding forms, common brass (C28000/CZ108, 60/40) is more economical while still maintaining good formability.

Q2: What brass sheet thicknesses can you press and stamp?

We process brass sheet from 0.3 mm foil (for fine blanking and spring contacts) up to 5 mm thick strip for heavy structural brackets. The optimal range for high-speed progressive die stamping is 0.5–2.0 mm. Thicker materials (2–5 mm) are formed on hydraulic presses using compound and progressive tools with higher-clearance die sets.

Q3: Can brass stampings be supplied with electroplated finishes?

Yes. We offer bright nickel, semi-bright nickel, tin-lead, pure tin (bright or matte), silver, chrome, and gold plating on brass stampings through our approved electroplating partners. Plating thickness specifications and adhesion testing per ASTM B487/B568 are confirmed before production. Most plated parts are supplied in individual polybags to prevent contact corrosion.

Q4: What is the ASTM standard for brass sheet used in stampings?

Brass sheet and strip for stampings is supplied per ASTM B36 (brass plate, sheet, strip, and rolled bar), ASTM B19 (cartridge brass strip for drawing), and ASTM B121 (leaded brass plate, sheet, and strip). EN 1652 is the European equivalent. Material Test Certificates confirming chemical composition and mechanical properties are available with all orders.

Q5: Do you offer progressive die stamping for brass electrical terminals?

Yes. Progressive die stamping is our primary process for high-volume brass electrical terminals, connector contacts, and bus bar tabs. We achieve blanking and forming tolerances of ±0.05 mm on carrier-strip parts, with in-process inspection every 1,000 hits. Plating (tin, silver) is applied to finished parts in bulk barrel or rack configurations.

Q6: How do you prevent stress corrosion cracking (SCC) in deep-drawn brass parts?

Stress corrosion cracking in brass (also called season cracking) is caused by residual tensile stress combined with ammonia or amine environments. We prevent SCC by: annealing deep-drawn parts at 200–250 °C for 1 hour to relieve residual stress, avoiding ammonia-based cutting fluids, and specifying CZ106 (70/30 brass) which is more SCC-resistant than higher-zinc alloys. Parts for humid or chemical environments are always stress-relief annealed.

Q7: Can you manufacture brass perforated sheet and mesh panels?

Yes. We produce perforated brass sheet panels with round, square, slot, and hexagonal hole patterns in sheet thicknesses from 0.5–3 mm. Hole diameters from 1 mm upwards are standard. Custom perforation patterns for architectural, acoustic, or filtration applications are tooled from DXF files. Brass mesh can also be sourced and cut to size.

Q8: What tolerances do you hold on blanked brass washers and discs?

On blanked brass washers and discs we hold outer diameter to ±0.05 mm and inner bore to ±0.05 mm for high-speed press blanking. For close-tolerance applications, fine blanking achieves ±0.02 mm with perpendicular, burr-free edges. Thickness tolerance follows ASTM B36 strip tolerances (typically ±0.02–0.05 mm depending on nominal thickness).

Q9: Are your brass sheet metal parts RoHS compliant?

Our standard leaded brass alloys (CZ120, CZ121 with 3% lead) are exempt from RoHS Directive restrictions under Annex III exemption 6(a) for copper alloys containing up to 4% lead by weight. Lead-free brass alloys (CW510L, bismuth-brass, or silicon-brass) are available for applications where this exemption does not apply. We provide RoHS declarations with all standard orders.

Q10: What is the minimum order for custom brass stampings?

For new tooling: minimum production run of 1,000–5,000 pieces (depending on part value) to amortise tooling cost. For laser-cut brass prototypes: from 5 pieces with no tooling required, delivered in 5–7 days. For repeat orders on existing tools: minimum of 500 pieces per call-off. Blanket annual orders with monthly releases are welcomed for regular production parts.
