Custom Precision CNC Turning Brass Copper Components | OEM ODM Machined Parts For Industrial Use

Custom Precision CNC Turning Brass Copper Parts - Product Description

1. Product Overview

Our custom CNC turned brass/copper components are precision-manufactured to meet the most demanding industrial and electronic applications. Made from high-grade brass (H59/H62) or pure copper, these parts combine excellent electrical conductivity, corrosion resistance, and mechanical stability, ensuring reliable performance in connectors, terminals, and other critical assemblies. We specialize in OEM/ODM custom solutions, tailored to your exact specifications, drawings, or samples.

2. Key Product Advantages

✅ Ultra-High Precision Machining

Manufactured with advanced CNC lathes and Swiss-style turning centers, achieving tight tolerances up to ±0.01mm. Every part undergoes rigorous dimensional checks to guarantee consistent fit and performance, eliminating the need for secondary adjustments.

✅ Premium Copper & Brass Materials

We use only high-quality brass (H59, H62) and pure copper stock, selected for their superior electrical conductivity, thermal performance, and resistance to oxidation. These materials ensure long-term reliability in even harsh operating environments.

✅ Full Customization Capabilities

From simple pins and terminals to complex multi-feature components, we handle custom designs of all sizes and geometries. Our services include drilling, tapping, knurling, and surface finishing, so you get a part built exactly for your application.

✅ Strict Quality Control

Every batch undergoes comprehensive quality inspections, including dimensional verification, surface finish checks, and functional testing. We adhere to ISO and RoHS standards, ensuring your parts meet all industry requirements and are free from defects like burrs or scratches.

✅ Fast & Flexible Production

With in-house manufacturing facilities, we offer fast lead times: samples in 3-5 days and bulk orders in 7-15 days, with rush orders available. We support both small-batch prototyping and high-volume production runs.

✅ Wide Range of Surface Treatments

Choose from a variety of finishes to enhance performance and durability: natural brass/copper, tin plating, nickel plating, gold plating, silver plating, or passivation. These treatments improve conductivity, corrosion resistance, and solderability.
