Alloy requirements  ◆Suitable for all copper alloy, including pure copper (99.85%), Work best on brass alloy.
  ◆Can be used to lower the casting temperatures and increase the cast-ability and fluidity of the aluminum bronze, red brass and tin bronze.
  ◆Also proper for aluminum high pressure casting, parts will come out bright and shiny
  ◆Can be used on the dross which is being removed from the melt to get the trapped metal to flow back to the pool of liquid metal
  ◆Also good for nickel, silver and gold to clean and grain refine.
Method of use   ◆Products shall be free of any moisture.
  ◆Any adjustments to the aluminum or zinc content of the melt should be made prior to adding Desofin.
  ◆The surface of the melt should be reasonably free of slag.
  ◆Desofin should be added to the melt by immersing the capsules at least 100 cm. below the liquid metal surface using a bell shaped plunger and the furnace should be in low tap.
  ◆Stir the melt uniformly after putting Desofin into it.
Expected benefits  ◆Improved Fluidity of the metal to be cast.
  ◆Lower the casting Temperatures are possible depending on the size of the part to be cast and the type of mold to be used. Generally between 940 and 980 degrees C for beryllium copper molds.
  ◆Lower temperatures are possible if the iron steel molds are used.
  ◆Cracking Tendencies of the parts to be cast are greatly reduced and most often, cracks are eliminated.
  ◆The occurrence of the sinks is greatly reduced.
  ◆Lead is more uniformly distributed in the fine grain structure.
Potential savings  ◆Savings over the cost of purchasing fine grained ingot.
  ◆Reduction of casting scrap.
  ◆Reduction in finishing and rework costs.
  ◆Energy savings resulting from lower casting temperatures.
  ◆It is not necessary to refine foundry scrap, i.e. gates, risers and turnings already grain refined.
