Large Silver Tungsten (AgW) Contact Parts 80g | Contains Pure Silver & Copper | For Radio Equipment & Assets

Product Description:
This is a large silver-tungsten (AgW) alloy contact part, removed from railway facility equipment and with a history of actual use.
Due to the recent historic surge in precious metal and rare metal prices (as of March 2026), the material value is extremely high. It is ideal not only for practical use, such as improving radio performance, but also as a tangible asset (urban mine) for future value appreciation.
[Product Features]
Asset Value: Contains pure silver (Ag), high-purity copper (Cu), and tungsten (W). Also suitable as a collection for inflation hedging.
Practical Performance: Combines silver's conductivity with tungsten's arc resistance, demonstrating exceptional effectiveness in improving reception sensitivity and preventing contact burnout.
[Condition and Measurement]
Sold as-is: This is an uncleaned used item. It has burn marks, scratches, and discoloration from electrical contact.
Weight: Approximately 80g in total (please allow for slight errors as this was measured with a simple home scale).
Individual Differences: As these are removed from railway equipment, each item will have slight differences in size, thickness, and shape. We deliver them in their original condition, so please purchase only if you understand and accept these individual differences.

This product is equivalent to the standard specification 'AgW60 (60% Silver: 40% Tungsten)' adopted as the main contact for large circuit breakers. In electrical contact engineering, this is the most reliable mixing ratio for achieving both high conductivity and resistance to arc discharge, and the engraving '6X' supports this.
