  • Alloy No C1100
  • Characteristics High electrical conductivity, drawing processing, non-corrosion, atmosphere corrosion resistance, ductility
  • Applications Switches, Relay
    Transistors, Circuit breaker
    Transformer
    Cars
  • Other information It dissolves high-purity copper, removes impurities through cleaning process of molten metal, and has high electric conductivity and excellent mechanical and physical properties.

Phosphorus Deoxidized Copper

  • Alloy No C1201, C1220
  • Characteristics High electrical conductivity, drawing processing, non-corrosion, atmosphere corrosion resistance, ductility
  • Applications Motor Vehicle: radiator, gasket
    Construction: interior and exterior material
    Other: Kitchen utensils, heat exchanger
  • Other information High purity material was used to control the amount of oxygen. That enhanced electronic and thermal conductivity, non-corrosion, and ease of welding, drawing processing. It can also be used for electronic parts that require high elasticity.

 

Oxygen - Free Copper

  • Alloy No C1010, C1020

Company introduction

Thank you very much for visiting our website.

Copper is one of the oldest and friendliest metals Humankind has known.

Since our foundation of the nation’s first rolling mill company taking part in the non-ferrous metal industry which was an unexplored field in 1968, we have grown up as a creditable company manufacturing and provides the best quality products at the right time at the right price.

With our customers’ hearty support, we will continue our efforts to develop new materials. The reasons why we have grown this much is not only from our customers, but also our employees working with the philosophy, harmony, commitment and creativity. Our new Poseung factory will upgrade all of our products, services and image.

We firmly promise to devote ourselves to be other global-oriented and future-oriented as a pioneer in non-ferrous material industry in the 21st century.

We hope you enjoy surfing our website. Thanks.
