ac 米兰官网 Co., Ltd. Has Launched a High-Purity Oxygen-Free Copper Wire, “PCUHD”
~ High Quality ac 米兰官网 Wire Made Using Unique Manufacturing Methods ~

June 17, 2014

ac 米兰官网 Co., Ltd. has succeeded in developing PCUHD and launched full-scale sales of the product from this fiscal year. PCUHD stands for Pure Copper Ultra High Drawability. It is an oxygen-free copper wire product into which carefully-selected raw materials are cast in the process where contamination due to inclusions and impurities is strictly controlled.

Characteristics

By combining a molding process that uses no heat resistant materials with post-processing free from hot extrusion or rolling processes, the product can be mass-produced in a way that excludes inclusions and impurities. While the product is a 4N grade material (copper purity 99.99%), it possesses high malleability and drawability that allows processing up to superfine wires.
Oxygen is one of the most common impurities in copper products. For this reason, no gas burners are used during the manufacturing processes and the insides of the equipment are filled with noble gases. Through these methods we have succeeded in controlling oxygen to 5ppm, which is below the standard required for ac 米兰官网.

Fields of Application

  • Acoustic cables; internal wiring material for acoustic equipment
    By controlling the amount of oxygen contained in the product, it is possible to reduce the amount of “voids (bubbles) within the material that hinder the transmission of electric signals/ oxides.”
  • Material for connection conductors used in semi-conductors
    The product’s low level of inclusions means it has excellent processability into the superfine wires required for making narrow pitch connections.
