- KEEP OUT OF REACH OF CHILDREN - NOT ALL FLUX IS THE SAME! Every other type of flux that we have tried has produced a strong unpleasant odor, even in our well vented shop. Because flux is highly poisonous and corrosive we do not believe this to be a good thing for our health or shop equipment. Asbury 770 makes us feel better about the quality of air we are breathing during the casting process. I bought a 500lb drum last year. I do not have a lot of free space and need to get rid of the surplus. When it is gone there will be no more. Asbury Coverflux 770 is a professional grade cleaning and drossing flux. It promotes low metallic content in the dross (less wasted metal) and aids in keeping furnace walls clean. It has good cleaning and easy skimming properties. This flux is used in both crucible and reverb type furnaces when the temperature is in the 1275-1350 Deg F. range. Flux is a necessity when using scrap material in the melt. It helps impurities and slag (crud) float to the top of the melt. It also creates a floating layer on top of the molten metal that protects the molten metal from oxidation. When the metal has melted the dross layer is skimmed off and second application of flux is stirred in. After the second application has had time to react, the final dross is skimmed off to reveal a clean, mirror like pool of molten metal. This process will result in a better surface finish and improved material strength in your part. Using a good flux helps to recover metal that would otherwise be stuck to the dross and lost in skimming. Can be used in hot crucibles or reverb furnaces. Only a small quantity is needed (see chart below), so 10 Lbs will provide many melts! Use 1/4 to 1/2 lb. flux per 100 lb. of molten metal, depending on cleanliness of the melt. Apply 1/2 of the flux with the initial solid charge. Heat the charge to pouring temperature. Skim the initial dross from the melted charge and carefully stir in the remaining flux to the molten metal. A powdery reddish color dross low in metallics will result. The metal is now ready to be skimmed of final dross and poured. Do not exceed 1420 degrees Fahrenheit. For small batch use the following amounts are recommended: * Includes Material Safety Data Sheets and Manufacturers Technical Data sheets.
