When sourcing faucets from an overseas manufacturer, many buyers focus first on appearance, finish options, pricing, and production capacity. However, the internal material selection of a faucet often determines its long-term performance, compliance status, and market acceptance.
For professional buyers such as plumbing distributors, home improvement retailers, construction companies, and private-label brands, faucet material is not simply a manufacturing detail—it is a critical purchasing decision.
A faucet that looks premium but uses unsuitable brass alloys may experience corrosion, leakage, certification challenges, or customer complaints after installation. On the other hand, selecting the correct brass material can improve durability, simplify certification approval, and strengthen brand reputation.
This is why experienced buyers working with a faucet factory or OEM supplier need to understand the differences between common faucet materials, including 59 brass, DZR brass, and low-lead brass, as well as how these materials relate to U.S. plumbing standards.
Most traditional faucets are manufactured using brass because of its excellent combination of strength, machinability, corrosion resistance, and casting performance.
Brass is an alloy primarily made from:
Copper
Zinc
Small amounts of other elements
By adjusting the alloy composition, manufacturers can create brass materials with different performance characteristics.
For faucet production, the most important factors include:
Copper content
Lead content
Dezincification resistance
Corrosion performance
Machining characteristics
Certification compliance
A professional OEM faucet manufacturer must select materials based on the target market, certification requirements, and intended application—not simply manufacturing cost.
59 brass refers to brass containing approximately 59% copper. It is one of the most commonly used brass alloys in faucet manufacturing.
Its balanced composition provides:

Actual alloy composition
Lead content control
Casting quality
Surface treatment quality
Supplier quality management
For markets with strict drinking water regulations, standard brass alloys may require additional compliance verification.
DZR stands for Dezincification Resistant brass.
Dezincification is a corrosion process where zinc is selectively removed from brass when exposed to certain water conditions. Over time, this can weaken the material structure and affect product reliability.
DZR brass is specially formulated to resist this type of corrosion.
DZR brass is particularly suitable for environments where water chemistry creates higher corrosion risks.
Applications include:
Commercial buildings
Hospitality projects
Coastal regions
High-use plumbing systems
For professional buyers supplying demanding markets, DZR brass can reduce long-term failure risks.
Water quality varies significantly between regions.
Factors such as:
High mineral content
Chloride exposure
Aggressive water chemistry
can accelerate brass corrosion.
DZR brass provides additional protection compared with standard brass alloys.
For OEM customers developing premium faucet collections, DZR brass can become a valuable product differentiator.
Marketing advantages include:
Enhanced durability
Professional-grade construction
Improved corrosion resistance
Low-lead brass is manufactured to meet strict drinking water safety requirements by limiting lead content in wetted components.
These requirements are commonly evaluated through standards such as NSF/ANSI/CAN 372 for lead content verification, which establishes a methodology for determining and verifying lead content compliance in drinking water components.
Lead can potentially migrate from plumbing components into water, which has resulted in increasingly strict regulations worldwide.
For U.S. buyers, lead content is one of the most important material considerations.
For faucets sold in the United States, manufacturers must comply with strict lead requirements and drinking water safety standards for products that come into contact with drinking water, including requirements evaluated under NSF/ANSI/CAN 61.
Key requirements include:
Maximum weighted average lead content of 0.25% on wetted surfaces
Compliance with applicable U.S. drinking water regulations
Testing and certification through recognized programs
Many U.S. buyers require faucets with certifications such as:
cUPC certification
NSF/ANSI 61 compliance
NSF/ANSI 372 lead content requirements
A qualified OEM supplier should be able to provide documentation proving material compliance.
Choosing a faucet supplier involves more than asking: “Is this faucet made from brass?”
Professional buyers should evaluate several technical factors.
OEM buyers should request:
Brass alloy specifications
Material test reports
Lead content testing results
Supplier quality documentation
A reliable faucet manufacturer should have clear control over raw material sourcing.
For North American markets, buyers should also verify whether suppliers can support plumbing certifications such as cUPC certification from recognized certification bodies including IAPMO R&T.
Different markets require different standards.
For the United States and Canada, buyers commonly evaluate:
cUPC certification demonstrates that plumbing products meet applicable North American plumbing standards.
This standard evaluates whether materials used in drinking water components may affect water quality.
This standard verifies lead content compliance.
A faucet factory experienced in exporting to North America should understand these requirements during product development—not after production.
While brass is important, a complete faucet material evaluation should also include:
A high-quality ceramic cartridge affects:
Leak prevention
Operation lifespan
User experience
Stainless steel may be used for:
Pull-down faucet hoses
Springs
Fasteners
Internal components
Buyers should consider corrosion resistance and durability.
Material selection should also match finishing requirements.
Common finishes include:
Chrome plating
Brushed nickel
Matte black
PVD coating
Premium PVD finishes require strict surface preparation and coating control to ensure durability.
For OEM buyers targeting the U.S. residential market, material selection is only part of compliance. Water efficiency requirements may also influence faucet specifications, especially for brands seeking sustainability-focused positioning.
Products meeting EPA WaterSense specifications are independently certified for water efficiency and performance.
