As I understand it, phosphorus is often used to degas copper alloys, particularly brasses. Depending on the amount of excess phosphorus the alloy can get harder and may be used as spring-stock i.e., phosphor bronze springs. However, the zinc content of the particular alloy is where the potential problem lies. Without info on the zinc content you can't tell if you will have a possible de-zincification problem with your screws. If no other data is available you would be best to stick with silicon bronze.
