PHOSPHOR COPPER is most commonly used as deoxidizing agent in the smelting of copper and copper alloy. As Japanese Industrial Standards indication approval plant, we are always manufacturing the high purity product that exceeds the stipulated value impurity. The addition of PHOSPHOR COPPER at the rate of 0.01`0.03% as phosphorus in sufficient for pure copper and bronze casting. In this regard, it is desired that the added phosphorus will not remain in the molten metal after deoxidizing treatment. Furthermore, the addition of more phosphorus to bronze casting will produce phosphor bronze casting that has better mechanical property and abrasion resistance than ordinary bronze.

We are manufacturing the Shot form PHOSPHOR COPPER with the same composition as the plate form product. We developed a unique manufacturing facility in August 1960. Since then, our intensive research efforts have been directed to the further development of this type of products and at present the Shot form PHOSPHOR COPPER of following sizes is manufactured at our plant. This product has been used in great quantities since August 1960 at Japanese famous rolling mills with exceedingly good reputation.

We are producing the shot form EUTECTIC PHOSPHOR COPPER METAL (phosphorus content 8.38%, melting point 714). This product is used for the pro-eutectic crystal silicon micro-pulverization of alloy for hypereutectic Aluminum-Silicon casting. It is grinning good reputation.
