■ PHOSPHOR COPPER METAL(Plate form)
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.

■ PHOSPHOR COPPER METAL(Shot form)
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.

■ EUTECTIC PHOSPHOR COPPER METAL
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.
