More Metal for Your Money

 

At approximately 4000 kg/m3 (250 lb/ft3), the bulk density of Sorelmetal® is more than three times that of steel scrap. This much higher density dramatically reduces the amount of storage space required. It can also minimize handling during charge make up, reduce furnace charging time and allow better electrical efficiency when melting with induction furnaces. The carbon present in Sorelmetal® is chemically combined and therefore goes into solution much more quickly and with less energy required than when adding a recarburizer to steel scrap. For all these reasons, the bottom line result is significant overall cost savings when using Sorelmetal.

Due to its low manganese level and dilution effectiveness, most castings produced with Sorelmetal® can be made as cast if desired, eliminating costly heat treatment. This is particularly attractive for producing castings with high impact resistance. Additionally, castings alloyed with copper (for added strength) offer improved machinability.

Highest Performance Low Effective Cost

 

With Sorelmetal®, foundrymen can produce highly machinable Ductile Iron castings, up to 60 cm (24 inches) thick, with excellent toughness even at extremely low Arctic temperatures. Sorelmetal® 's unique versatility enables you to make 100 g (4 oz.) castings that are as machinable as castings weighing 200 tonnes. Better still, the low manganese content of Sorelmetal® enhances the mechanical properties of crankshafts and gears, making it an ideal component in their production.

Sorelmetal® 's undisputed superiority has been confirmed in thousands of cases worldwide. Ductile Iron foundrymen report improved physical properties, reduced shrinkage defects, higher casting yield and more consistent Ductile Iron casting properties when Sorelmetal® is included in the metallic charge.

Compared to alternative ferrous charge materials, Sorelmetal® has lower energy requirements for melting. With a melting temperature of 1145°C (2095°F), Sorelmetal® goes into solution very rapidly and increases the melting rate of the furnace. The metallic yield for Sorelmetal® (the amount of metal tapped versus the amount of metallics charged) is also higher than alternative iron units.
