INSTRUCTIONS FOR USING
BELMONT ALLOY “D” DEOXIDIZER
PRODUCT NO. 4923
“D” DEOXIDIZER IS AN ALLOY DESIGNED TO DEOXIDIZE AND DEGASIFY THE TIN BRONZE
TYPE OF FOUNDRY ALLOYS, SUCH AS 85/5/5/5, 88/10/2, 88/8/4/, NAVY M, 80/10/10, BEARING
BRONZE AND SIMILAR COPPER BASE ALLOYS WHICH CONTAIN TIN, LEAD AND ZINC IN
VARYING AMOUNTS.
FOR MOST EFFECTIVE RESULTS USE ABOUT 4 TO 5 OUNCES PER 100 LBS. OF METAL
TREATED. “D” DEOXIDIZER SHOULD BE ADDED ABOUT 3 MINUTES BEFORE THE METAL IS
TO BE POURED. THE BEST PROCEDURE TO FOLLOW IS TO PULL THE CRUCIBLE FROM THE
FURNACE, SKIM IT OFF, ADD THE REQUIRED AMOUNT OF “D” DEOXIDIZER IN THE
PROPORTION OF 4 TO 5 OUNCES OF METAL MELTED. AFTER “D” DEOXIDIZER IS ADDED TO
THE METAL IT SHOULD BE STIRRED GENTLY FOR ONLY ONE OR TWO REVOLUTIONS,
SKIMMED, AND THEN IT IS READY TO BE POURED INTO THE MOLDS.
“D” DEOXIDIZER WILL ACTUALLY INDICATE THAT IT IS FUNCTIONING PROPERLY BY THE
FACT THAT IT WILL SHOW A DECIDED SHRINK IN THE SPRUE OR IN THE RISERS AS IT
SOLIDIFIES. THE PHYSICAL PROPERTIES, SUCH AS ULTIMATE TENSILE STRENGTH AND
ELONGATION SHOULD BE NOTICEABLY IMPROVED. THE STRUCTURE WILL BE MORE
CLOSE-GRAINED AND IT WILL ALSO HAVE A DECIDED EFFECT IN IMPROVING PRESSURE
TIGHTNESS AS WELL AS THE APPEARANCE OF THE CASTINGS.
IF THERE IS ANY FURTHER INFORMATION DESIRED DO NOT HESITATE TO CALL ON US AND
WE WILL BE GLAD TO EXTEND ALL POSSIBLE HELP.
“D” DEOXIDIZER DOES NOT CONTAIN ELEMENTS THAT COULD BE INJURIOUS TO ANY TIN
BRONZE ALLOY. SINCE “D” DEOXIDIZER CONTAINS PHOSPHOROUS, IT IS UNNECESSARY
TO MAKE ANY FURTHER INDEPENDENT ADDITIONS, SUCH AS PHOSPHOR-COPPER.
