Our Copper Sleeve Product Range
As a leading copper sleeve manufacturer, we specialize in three main product categories that cater to diverse industrial needs:
1. Precision Copper Sleeves (Metal Bushings)
Our flagship product, these precision-machined copper sleeves feature smooth inner walls and exact dimensions achieved through CNC turning. The knurled middle section significantly increases assembly friction, preventing slippage during operation. After zinc plating for rust prevention, these durable components offer excellent corrosion resistance and long service life.
Key features:
- Material options: Iron, stainless steel, brass, aluminum
- Customizable dimensions: Outer diameter, length, wall thickness
- Surface treatments: Zinc plating, tin plating, polishing
- Applications: Fasteners, wire harness connectors, instrument bushings, furniture hardware, mechanical positioning
2. Custom CNC Machined Copper Components
Our CNC machining capabilities allow us to produce complex copper components with exceptional precision. The brass connecting rods exemplify this expertise – formed in one piece with precise dimensions and smooth surfaces free of burrs. Made from high-quality brass, these components offer excellent electrical and thermal conductivity while resisting oxidation and corrosion.
Customization options include:
- Material alternatives: Phosphor bronze, copper, aluminum, iron
- Dimension adjustments: Size, structure, shape
- Surface finishes: Tin plating, zinc plating, polishing
- Typical uses: Connectors, automotive parts, new energy equipment, medical instruments, electrical terminals
3. Stamped Copper Connectors and Terminals
For electrical applications, our stamped copper components provide reliable conductivity with precision engineering. The brass stretched copper shell (connector terminal housing) demonstrates our stamping expertise – formed seamlessly in one piece with compact structure and precise positioning. These components maintain stable conductivity while resisting corrosion and oxidation.
Key advantages:
- Material flexibility: Multiple copper alloys available
- Custom specifications: Size, structure, and premium surface treatments like gold, silver, or nickel plating
- Target applications: Aviation plugs, new energy connectors, wire harness terminals, sensors
