Nickel-Plated Nuts & Copper Metal Turning Parts

Material & Basic Specifications

We use C36000 brass, known for its excellent machinability and stable performance in precision manufacturing.

• Outer diameter tolerance: ±0.01 mm

• Length tolerance: ±0.02 mm

• Thread inspection: 6H thread gauge compliant

• Production efficiency: 2 pcs per minute (including drilling operations)

Knurled patterns are formed using dedicated tooling, ensuring uniform depth and consistent grip strength of ≥50 kg.
Nickel plating is applied to enhance corrosion resistance.

Nickel-Plated Nuts

Corrosion-Resistant, High-Precision, Fully Verified Quality

Our nickel-plated nuts are designed for consumer electronics applications and precision assemblies. Every performance parameter is supported by authoritative testing reports and validated through real-world use.

All products comply with international standards such as: GB/T 196-2003, ISO 4042:2020, ASTM B733

Material & Plating Quality

• Base materials: high-quality stainless steel or brass

• Nickel plating thickness: 8–12 μm (per GB/T 6462 standard)

• Optional chrome layer: 0.3–0.5 μm for enhanced protection

Advanced electroplating or electroless nickel plating processes are used.
Electroless Ni-P coatings reduce porosity by 30% compared to conventional electroplating, ensuring uniform coverage even on complex geometries such as threads.

Surface quality features:

• Bright and smooth finish

• No spots, pinholes, or peeling

• Passed GB/T 5270-85 adhesion test with zero coating delamination

Corrosion Resistance & Durability

• Standard nickel-plated nuts: ≥96 hours NSS salt spray resistance

• High-end electroless nickel: ≥1000 hours salt spray resistance

These results are not theoretical - they are verified through real-world applications in marine, chemical, and outdoor environments, ensuring extended service life and reduced maintenance costs.

Dimensional Accuracy Control

Each batch undergoes sampling inspection, with data archived and available upon request.

Ensures precise fit for both automated assembly and manual installation, eliminating failures caused by dimensional deviations.

Thread Accuracy

6H / 6g standard

Dimensional Tolerance

≤±0.01 mm

Pitch Error

≤0.005 mm

Precision Forming with Excellent Conductivity

Components produced through copper metal turning are widely used in electronics, electrical systems, communications, and automotive industries due to their superior electrical and thermal conductivity.

Using advanced CNC lathes and precision grinding equipment, we ensure dimensional accuracy and interchangeability for every component.

Material Selection & Purity Assurance

We use high-quality brass materials such as H59 and H62, with strict control of copper content:

• C36000 brass copper content: 57%–59%

• No impurities or porosity

This guarantees excellent conductivity and thermal performance, fully matching material specifications required by high-end electronic and electrical products.

Precision Machining & Consistency

• Fully automated CNC machining systems

• Professional inspection equipment:
→ Profile projectors
→ Hardness testers
→ Surface roughness testers

Performance metrics:

• Machining accuracy: IT6–IT8 grade

• Surface roughness: Ra ≤0.8 μm

• Key dimensional tolerances (steps, holes, length): ≤±0.008 mm

Batch production ensures minimal variation between parts, improving assembly consistency and reducing rework.

Customization & Performance Verification

We support full customization based on drawings or samples, including:

• Copper screws

• Copper bushings

• Copper connectors

All custom parts undergo sample production + full dimensional and performance testing before mass production.

Performance results:

• Tensile strength: ≥200 MPa

• Elongation: ≥30%

Maintains stable performance even in high/low temperature and humid environments.

Our expertise in copper metal turning ensures reliable performance across demanding applications.

Consistency Between Data and Reality - Our Core Commitment
