Applications
| Brass Strip Grade / Alloy Family | Typical Applications | Why This Grade Is Chosen | Notes (Engineer / EPC Checklist) |
|---|---|---|---|
| Gilding Metal (CuZn5) – UNS C21000 / EN CW501L | Decorative trims, nameplates, medals/badges, fine stampings, luxury hardware covers, architectural inlays, embossing & engraving sheets/strips | Highest copper content → excellent formability, deep embossing response, superior surface finish. | Best for appearance-critical parts; specify finish/temper to avoid waviness during stamping. |
| High Copper Brass (CuZn15) – UNS C23000 / EN CW502L | Electrical connectors (non-high-current), terminals & clips, lamp parts, radiator & HVAC accessories, general presswork, decorative-industrial hybrid components | Good corrosion resistance + better strength than CuZn5 while retaining strong formability. | Good “balanced” grade for stamping; confirm conductivity requirement if electrical use is critical. |
| Cartridge Brass (CuZn30 / 70-30) – UNS C26000 / EN CW505L | Deep-drawn components, electrical terminals, switchgear parts, transformer & motor accessories, ammunition components, press-fit parts, washers & spacers, HVAC fittings stampings | Industry standard for deep drawing and stamping with reliable ductility and consistent grain structure. | Specify grain/temper for deep draw (Earing control); confirm surface condition for plating. |
| Common Brass (CuZn37 / 63-37) – UNS C27200 / EN CW508L | General-purpose strip for fabrication, hinges, brackets, clips, architectural strips, ornamental fittings, low-stress mechanical parts, general hardware & fastener components | Cost-effective general brass with good workability and moderate strength. | Not a “deep-draw specialist” like CuZn30; for tight forming radii specify annealed temper. |
| Free Cutting / Leaded Brass (CuZn39Pb3) – UNS C36000 / EN CW614N | Machined components from strip blanks, precision parts requiring turning, inserts, threaded electrical/mechanical parts, watch/clock hardware, instrument parts | Lead improves machinability, chip break, tool life → faster cycle time on CNC. | Lead is a compliance risk (RoHS/REACH / potable water). Do not use unless allowed in project specs. |
| Leaded Brass (CuZn40Pb2 family) – EN CW617N / UNS family | Plumbing & sanitary component blanks (where lead is permitted), valve parts, machined fittings, general turned parts, industrial connectors | High machinability + good hot workability for fitting/valve manufacturing routes. | Prefer lead-free alternatives for export plumbing; specify lead max limits if required. |
| DZR Brass (Dezincification Resistant) – EN CW602N (common) | Potable water / plumbing parts in aggressive water, valve & faucet components, plumbing connectors, marine plumbing fittings, heat/corrosion exposed water systems | Designed to resist dezincification in chloride/low-alkalinity water → longer service life. | DZR is not just “chemistry” — specify DZR test/acceptance requirement in PO (critical for consultants). |
| Lead-Free / Eco Brass (Si-brass) – UNS C69300 / EN CW724R | RoHS/REACH compliant plumbing & water-contact parts, EV/energy connector components, sustainable hardware, premium sanitary parts, export-grade fittings & connectors | Low/near-zero lead + good strength/corrosion performance; compliance-friendly for global projects. | Confirm certification requirements (potable-water approvals are project/region specific). |
| Naval Brass (CuZn39Sn1) – UNS C46400 / EN CW712R | Marine hardware strip parts, shipbuilding components, corrosion-resistant fittings, offshore equipment components, marine electrical/mechanical parts | Tin addition improves seawater corrosion resistance and dezincification resistance vs standard brass. | Specify service environment (seawater/splash zone) and temper to control stress cracking risk. |
| Admiralty Brass (Condenser Brass) – UNS C44300 (common condenser family) | Heat exchanger & condenser-related strip components, tube-sheet accessories, marine/industrial heat-transfer support parts, cooling-water system components | Traditionally used for heat-transfer duties with improved corrosion resistance in certain waters. | Often specified by end-use standard; confirm whether buyer needs tube spec (B111) or strip spec. |

Weight Calculation (Theoretical):
Weight (kg/m) = t(mm) × w(mm) × ρ(g/cm³) × 0.001
Using ρ = 8.50 g/cm³ for brass strips.
Important:
Weight (kg/m) = t(mm) × w(mm) × ρ(g/cm³) × 0.001
Using ρ = 8.50 g/cm³ for brass strips.
Important:
- Actual density varies by brass grade (Zn/Pb/Sn/Si content). For EPC bids, treat this as theoretical only.
- If weight tolerance is contract-critical, lock density (ρ) and thickness tolerance in the purchase order.
