Brass Antenna Spring

Solution

Product Overview

Brass springs are precision-engineered elastic components manufactured from high-conductivity, corrosion-resistant brass materials. They are widely used in RF communication and antenna systems due to their stable mechanical performance, excellent electrical characteristics, and non-magnetic properties. These springs ensure reliable signal transmission and grounding across a variety of high-frequency applications.

Features

1. Superior Conductivity: Made from C26000 brass alloy (70% Cu, 30% Zn) with a conductivity rating of 28% IACS (International Annealed Copper Standard), ensuring efficient signal transmission with minimal loss (typically <0.5dB at 2.4GHz).

2. Mechanical Durability: Features a spring constant of 0.8-1.2 N/mm and fatigue resistance exceeding 50,000 compression cycles at 20% deflection, maintaining structural integrity under repeated stress.

3. Corrosion Resistance: Electroplated with 3-5μm nickel undercoating + 0.2μm gold finish, achieving 96+ hours salt spray resistance (ASTM B117 standard) while maintaining contact resistance below 10mΩ.

4. Thermal Stability: Operates reliably across -40°C to +125°C with a thermal expansion coefficient of 20.5 μm/m·°C, ensuring consistent performance in extreme environments.

5. Precision Dimensions: Manufactured to ±0.05mm tolerance with standard wire diameters of 0.3-0.8mm and pitch accuracy within ±0.02mm, enabling perfect impedance matching (50Ω±5% at 1-6GHz range).

6. Customizable Design: Available in compression, torsion, or helical configurations with optional beryllium copper cores (C17200) for increased tensile strength (up to 1400MPa) when required for specialized applications.
