Black Aluminum Oxide Threaded Standoff Extender Pin for Manual Gear Shifter and Long Shift Knob Extension

Material
The Black Aluminum Oxide Threaded Standoff is crafted from high-purity aluminum alloy, renowned for its lightweight properties, exceptional corrosion resistance, and mechanical strength. The surface is treated with a black anodized coating using aluminum oxide (Al₂O₃), which enhances durability and provides a sleek, uniform finish. This oxidation process not only improves wear resistance but also ensures excellent electrical insulation, making it ideal for applications requiring both functionality and aesthetics.

Manufacturing Process
The production of this standoff involves lath machine /precision CNC machining to achieve accurate thread dimensions and tolerances. After machining, the component undergoes electrochemical anodization:

Cleaning: Removal of impurities to ensure coating adhesion.

Anodizing: Immersion in an acidic electrolyte bath to form a porous aluminum oxide layer.

Dyeing: Introduction of black dye into the oxide pores for consistent coloration.

Sealing: High-temperature sealing to lock in the color and enhance corrosion resistance.
Rigorous quality checks, including dimensional verification and coating thickness testing, ensure compliance with industry standards.

Applications
This standoff is widely used across industries for secure and insulated spacing:

Electronics: Mounting PCBs, separating components to prevent short circuits.

Industrial Machinery: Structural support in equipment requiring vibration resistance.

Automotive: Securing electrical systems and sensors in harsh environments.

Telecommunications: Assembling antenna systems and communication devices.
Its black finish blends seamlessly with modern designs, while the aluminum oxide coating ensures long-term reliability in humid or corrosive conditions.
