Product Range

Brass DZR Fittings

Our Dezincification Resistant Brass fittings are engineered to excel in applications where standard Brass would fail due to dezincification corrosion. These premium fittings feature a unique microstructure that significantly reduces zinc leaching even in aggressive environments. Our DZR Brass fittings portfolio includes threaded connectors, compression fittings, adapters, elbows, tees, couplings, unions, and valves. Each fitting undergoes rigorous testing to ensure compliance with international standards including EN 12164, EN 12165, ISO 6509, and ASTM B962. These fittings are particularly valuable in potable water systems, marine applications, and installations in environments with high chloride content where conventional Brass would deteriorate rapidly.

Dezincification Resistant Brass Components

Our Dezincification Resistant Brass components provide exceptional durability in corrosive environments while maintaining excellent machinability and mechanical properties. These components are manufactured from premium DZR Brass alloys with carefully controlled composition, particularly the critical zinc-to-copper ratio and addition of inhibiting elements like arsenic, antimony, or phosphorus. Our comprehensive range includes plumbing components, electrical connectors, hydraulic fittings, pneumatic system components, and specialized industrial parts. The superior corrosion resistance of these components significantly extends service life in challenging environments, making them particularly valuable for critical infrastructure and systems where replacement would be costly or challenging.

Brass DZR Machined Parts
Our precision Brass DZR machined parts represent the pinnacle of manufacturing excellence, combining advanced CNC technology with premium DZR Brass materials. These components feature complex geometries, tight tolerances (as precise as ±0.01mm), and exceptional surface finishes down to Ra 0.4μm. Our machining capabilities include multi-axis CNC turning, milling, drilling, reaming, threading, and grinding. We specialize in producing high-precision components such as valve bodies, pump components, gear housings, fluid control components, electrical terminals, and specialized threaded connectors. Each machined part undergoes comprehensive inspection including dimensional verification, material certification, and corrosion resistance testing to ensure uncompromising quality and performance.

DZR Brass Forgings
Our DZR Brass forgings deliver superior mechanical strength, dimensional stability, and corrosion resistance through our advanced hot and cold forging processes. The forging process aligns the grain structure of the Brass, significantly enhancing its mechanical properties and resistance to failure under pressure. Our forging capabilities include open die forging, closed die forging, and precision forging techniques capable of producing components weighing from 10g to 25kg with exceptional consistency. Typical forged DZR Brass products include valve bodies, pipe fittings, manifolds, pump components, flanges, and high-pressure connectors. The forging process creates a dense, homogeneous structure that contributes to the exceptional pressure ratings and resistance to stress corrosion cracking that characterize our forged components.

DZR Brass Casting Parts
Our DZR Brass casting parts combine complex geometries with excellent corrosion resistance, making them ideal for challenging fluid handling applications. We employ multiple casting technologies including gravity die casting, low-pressure die casting, continuous casting, and investment casting to produce components tailored to specific requirements. Our casting capabilities allow for the production of complex shapes with internal passages and variable wall thicknesses that would be impossible or prohibitively expensive to produce through other manufacturing methods. Typical cast DZR Brass products include pump housings, valve bodies, impellers, water meter housings, and manifolds. Each casting undergoes thorough inspection including radiographic testing, pressure testing, and chemical composition analysis to ensure structural integrity and performance.

Frequently Asked Questions

Q: What makes DZR Brass different from standard Brass? A: Dezincification Resistant Brass contains carefully controlled levels of inhibitor elements (typically arsenic, antimony, or phosphorus) and has a specific microstructure that prevents selective leaching of zinc from the alloy in corrosive environments. This results in significantly extended service life compared to standard Brass, which can experience rapid deterioration in certain conditions.

Q: Are your DZR Brass products suitable for potable water applications? A: Yes, our DZR Brass components are specifically designed for potable water systems and comply with international drinking water standards including NSF/ANSI 372, AS/NZS 4020, and European Drinking Water Directive requirements. We offer both traditional and lead-free variants to meet specific regional regulations.

Q: What international standards do your DZR Brass products comply with? A: Our products comply with multiple international standards including EN 12164, EN 12165, EN 12167, EN 12168 (European), ASTM B962 (American), AS 2345 (Australian), and ISO 6509 (International) for dezincification resistance testing. Material composition adheres to standards specific to each market we serve.

Q: How do I select the right DZR Brass grade for my application? A: Selection depends on several factors including operating pressure, temperature, corrosive elements present, mechanical load requirements, and regulatory compliance needs. Our engineering team provides comprehensive consultation to determine the optimal grade based on your specific application parameters.

Q: What is the maximum pressure rating for your DZR Brass fittings? A: Our standard DZR Brass fittings are rated for pressures up to 40 bar (580 psi), with exact ratings dependent on size, wall thickness, and configuration. For high-pressure applications, we offer reinforced designs rated up to 100 bar (1450 psi) with appropriate safety factors incorporated.

Q: Can you provide custom DZR Brass components with non-standard dimensions? A: Absolutely. Custom dimensions, thread types, special geometries, and application-specific modifications are our specialty. Our engineering team can work from your drawings, specifications, or concepts to develop components tailored precisely to your requirements.

Q: How does temperature affect the performance of DZR Brass? A: DZR Brass maintains excellent mechanical properties from -30°C up to 200°C. At elevated temperatures (above 150°C), there is a gradual reduction in tensile strength (approximately 15% at 200°C), which should be considered in design calculations for high-temperature applications.

Q: Is independent material certification available for your products? A: Yes, we provide comprehensive material certification including chemical composition analysis, mechanical property verification, and dezincification resistance test results. For critical applications, we can arrange third-party testing and certification from internationally recognized laboratories.

Q: What quality control measures do you implement during production? A: Our quality assurance program includes incoming material verification, in-process inspection at critical manufacturing stages, statistical process control, dimensional verification using coordinate measuring machines, material testing, pressure testing, and final inspection before packaging and shipment.

Q: How do DZR Brass components perform in seawater environments? A: Our DZR Brass exhibits excellent performance in seawater and marine environments, with dezincification resistance significantly superior to standard Brass. For optimal long-term performance in continuous seawater exposure, we recommend specific grades with enhanced antimony or arsenic content designed specifically for marine applications.

Q: Can your DZR Brass products be recycled? A: Yes, DZR Brass is 100% recyclable with no loss of properties when reprocessed correctly. We actively promote sustainability by minimizing waste in our manufacturing processes and using recycled Brass alloys where appropriate, without compromising on quality or performance.
