Introduction
C230 NuGold Brass, also known as red brass, is a copper alloy valued for its reddish color, corrosion performance, and balanced mechanical and thermal properties. This technical guide is written for engineers, designers, manufacturers, and procurement specialists to evaluate C230 NuGold Brass for part selection, fabrication, and production planning. The guide emphasizes actionable decision criteria: composition, physical behavior, corrosion resistance, typical uses, machining practices, cost drivers, environmental factors, high-temperature performance, and quality control measures.
What are the chemical and physical properties of C230 NuGold Brass?
Understanding the chemical composition and physical properties of C230 NuGold Brass is essential for selecting the alloy for functional, aesthetic, and manufacturability requirements. The main decision when evaluating C230 NuGold Brass is whether its balance of strength, ductility, conductivity, and corrosion resistance meets the application’s performance and processing needs.
What is the chemical composition of C230 NuGold Brass?
C230 NuGold Brass is specified as approximately 85% copper and 15% zinc. Copper provides electrical and thermal conductivity, ductility, and corrosion resistance; zinc increases strength and hardness while preserving good formability. The near 85/15 split yields a red-brass appearance and predictable mechanical characteristics for common engineering components.
How do the physical properties of C230 NuGold Brass influence its applications?
Key physical properties influence application fit: typical density ~8.4 g/cm3, tensile strength range often 310–380 MPa depending on temper and processing, and hardness values that vary by temper (for example H58 temper increases hardness). Electrical and thermal conductivity are lower than pure copper but still adequate for many fittings and electrical connectors. These properties favor uses where corrosion resistance and appearance are important while maintaining adequate strength for machined parts.
How does the corrosion resistance of C230 NuGold Brass compare to other brass alloys?
Corrosion resistance is a primary selection criterion for brass alloys used in wet, marine, or chemically active environments. Evaluate C230 NuGold Brass for applications where dezincification resistance, general atmospheric corrosion performance, and maintenance intervals are important.

| C230 NuGold Brass | 85% Cu, 15% Zn | ~310–380 MPa | Medium (varies with temper) | Good; moderate resistance to dezincification |
| C260 Brass | ~70% Cu, 30% Zn (cartridge brass) | ~300–400 MPa | Средний | Lower dezincification resistance than C230 |
| C464 Brass | Cu-Zn with ~1–2% Pb additions | Higher depending on Pb and tempers | Higher; leaded brasses machine well | Good mechanical corrosion resistance; dezincification risk depends on environment |
What are the corrosion resistance properties of C230 NuGold Brass?
C230 NuGold Brass exhibits good general corrosion resistance in atmospheric and fresh-water environments. The high copper content improves resistance to uniform corrosion. While not immune to dezincification in aggressive chloride-rich or high-oxygen environments, C230 generally performs better than high-zinc brasses (e.g., C260). For long-term installations, consider protective finishes, design choices that avoid stagnant water, and environmental controls.
How does C230 NuGold Brass compare to other alloys in terms of corrosion resistance?
Compared with high-zinc brasses, C230 NuGold Brass typically offers better resistance to dezincification and stress corrosion cracking due to its higher copper ratio. Compared with specialized dezincification-resistant (DZR) alloys, C230 is less resistant but often offers a superior balance of machinability, cost, and aesthetic appeal. Selection should weigh environmental aggression, required service life, and maintenance budgets.
What are the common applications of C230 NuGold Brass in various industries?

What are the machinability characteristics of C230 NuGold Brass?
C230 NuGold Brass typically machines well: it exhibits good ductility, moderate hardness, and produces continuous chips. Tool wear is lower than with ferrous alloys but can be increased by abrasives or improper coolant. The alloy responds well to tight tolerances and fine surface finishes if chips are evacuated and cutting parameters are optimized.
What are the best practices for machining C230 NuGold Brass?
Best practices include using sharp, polished cutting tools to reduce built-up edge, moderate to high cutting speeds with controlled feeds, and appropriate coolant or mist to avoid thermal build-up. Design for manufacturability recommendations: avoid thin walls that vibrate, include adequate fillets, specify achievable tolerances, and plan deburring and finishing steps. Monitor tooling for wear and use stable fixturing to prevent chatter and dimensional variation.
How does the cost of C230 NuGold Brass influence its selection for manufacturing projects?
Economic assessment should weigh raw material cost, machining yield, finishing requirements, and lifecycle maintenance. The central decision is whether C230 NuGold Brass delivers total cost advantage through durability and reduced maintenance versus cheaper base materials or higher-cost specialty alloys.
How does the cost of C230 NuGold Brass compare to other materials?
In raw-material terms, C230 NuGold Brass typically costs more than common steels and some aluminium alloys but less than specialty copper or nickel alloys. Machining costs are often lower than for harder or abrasive materials due to favorable machinability, but finishing and plating for appearance can add expense. Use a side-by-side cost comparison that includes lifecycle maintenance, replacement frequency, and assembly costs.
What are the long-term value considerations when using C230 NuGold Brass?
Consider durability, resistance to corrosion-related failures, maintenance intervals, and recyclability when calculating lifecycle cost.

How does C230 NuGold Brass perform in high-temperature applications?
High-temperature performance is a limiting factor for many copper alloys. The decision to use C230 NuGold Brass in thermal environments must account for thermal conductivity, expansion, and softening at elevated temperatures. Use caution where mechanical loads and elevated temperatures coincide.
What is the melting point of C230 NuGold Brass?
The approximate melting range for C230 NuGold Brass is near typical brass melting temperatures (around 900–940 °C), but service limits are much lower. Because mechanical properties degrade at elevated temperatures well below melting, assess allowable operating temperatures against strength and creep requirements for the application geometry and loading.
How does C230 NuGold Brass perform under thermal stress?
Under thermal cycling and sustained elevated temperatures, C230 NuGold Brass can exhibit softening and dimensional change from thermal expansion. Thermal conductivity is relatively high compared with steels, helping dissipate heat, but thermal expansion coefficients are significant and must be accommodated in assemblies. For sustained high-temperature service, evaluate mechanical property retention and potential for accelerated corrosion in oxidizing conditions.
What are the quality control measures essential when working with C230 NuGold Brass?
Quality control is central to ensuring component performance and repeatable manufacturing. The decision framework focuses on inspection methods, defect detection, traceability, and process controls to minimize variation and failure risk.
