PRODUCT INTRODUCTION

Copper rod is a kind of non-ferrous metal processing rod with good processing performance and high conductivity. It is mainly divided into brass rod (copper-zinc alloy, cheaper) and copper rod (higher copper content).

Brass rod is a rod-shaped object made of copper and zinc alloy, named for its yellow color. Brass with a copper content of 56%~68% has a melting point of 934~967 degrees. Brass has good mechanical properties and wear resistance, and can be used to manufacture precision instruments, ship parts, gun shells, etc.

Different zinc content will also have different colors. For example, if the zinc content is 18%-20%, it will be red-yellow, while if the zinc content is 20%-30%, it will be brown-yellow. In addition, brass has a unique sound when knocked, so Eastern gongs, cymbals, bells, trumpets and other musical instruments, as well as Western brass instruments are made of brass.

Copper rod is named for its purple-red color, has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and brazed.

The use of copper rods is much more extensive than that of pure iron. Every year, 50% of copper is electrolytically purified into pure copper for use in the electrical industry. The copper mentioned here must be very pure, with a copper content of more than 99.95%. A very small amount of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. The oxygen content in copper (a small amount of oxygen is easily mixed in during copper smelting) has a great influence on the conductivity. Copper used in the electrical industry must generally be oxygen-free copper.
