99.9% Pure Copper
-Material Ingredients: Copper CUAg: 99.9% Oxygen O balance. Conductivity ≥56ms/m, tensile strength Mpao≥295, density 8.9g/cm。
-The use of red copper is much wider than that of pure iron, with 50% of copper being electrolytic purified into pure copper every year for use in the electrical industry. The red copper mentioned here must be very pure, with a copper content of over 99.95%. A small amount of impurities, especially phosphorus, arsenic, aluminum, etc., can greatly reduce the conductivity of copper. The oxygen content in copper (which is easily mixed with a small amount of oxygen during copper smelting) has a significant impact on the conductivity, and copper used in the electrical industry generally must be oxygen free. In addition, impurities such as lead, antimony, and bismuth can prevent the crystallization of copper from binding together, resulting in heat embrittlement and affecting the processing of pure copper. This kind of pure copper with high purity is generally refined by electrolysis: using impure copper (i.e. crude copper) as anode, pure copper as cathode, and Copper(II) sulfate solution as。
-high-precision,Very little runout at the front and rear ends of the electrodes,Good discharge machining effect, long electrode life, and high discharge machining efficiency。
-Purpose: Used for discharge machining/tapping electrodes/special discharge machining, where the feed is rotated and the corresponding thread pitch is moved during discharge。
