Product Description

 

Product Introduction

Copper products exposed in the air are prone to oxidation and the formation of basic copper carbonate, which has high resistance, poor electrical conductivity and high power transmission loss; after tin plating, copper products form tin dioxide films in the air due to the properties of tin metal itself to prevent further oxidation.
