Buy & Import Antenna spring from Carbon Spring - India Wholesale Supply

The Antenna spring from Carbon Spring in Bangalore is a helical RF component manufactured from Stainless Steel 304 or Copper C10200 wire. It is used as a conductive and flexible element in mobile antennas, base stations, and wireless devices, ensuring consistent signal transmission under mechanical stress. The spring’s design balances electrical conductivity with fatigue resistance for long-term reliability.

Stainless Steel 304 offers corrosion resistance and a typical tensile strength of 500-700 MPa, while Copper C10200 provides superior conductivity (minimum 100% IACS) and is often tin-plated for solderability. Spring wire diameters range from 0.2 mm to 1.5 mm typical, with coil diameters and pitch tailored to the antenna’s mechanical requirements. The component meets typical RF industry standards for return loss and VSWR.

OEM antenna manufacturers and telecom infrastructure providers in India source these springs for integration into cellular and IoT devices. Carbon Spring’s location in Peenya, Bangalore, places it in a hub for precision engineering. Buyers should confirm wire grade, plating specifications, and packaging, as the listing does not specify MOQ or lead time.

Frequently Asked Questions About Antenna spring from Carbon Spring
Spring constants vary by wire diameter and coil geometry. Request the supplier’s load-deflection curve for the specific part number, as this is critical for mechanical fit in antenna assemblies. Typical values for SS 304 springs in this range are 0.5-2 N/mm.

Sourcing Antenna spring from Carbon Spring - India Import Guide

Before placing an order, confirm the spring’s material, wire diameter, and plating to match your antenna’s electrical and mechanical requirements. Request samples for prototype testing, as RF performance can vary with geometry. Ask for a material test certificate to verify the grade and conductivity of the wire used.

Discuss logistics with Carbon Spring, including Incoterms (FOB Bangalore or CFR to your port), packaging in anti-static bags, and lead time for bulk orders. For international shipments, ensure the supplier can provide a commercial invoice and packing list in English. Payment terms such as TT 30/70 or LC at sight are typical for new buyers.

Quality checks should include dimensional verification (wire diameter, coil diameter, pitch), plating thickness measurement, and electrical continuity testing. For critical applications, arrange a third-party inspection in Bangalore to validate the spring’s RF performance. Ensure all documentation, including test reports and compliance certificates, is provided for customs and end-user validation.
