SILAFONT® - 70 is a nearly eutectic, hardenable alloy with good casting properties for sand and coquille casting as well as die casting. It is characterised by high hardness after heat treating, high heat resistance and good running and gliding properties both in gliding against steel and for running cast parts of SILAFONT® - 70 against each other, if dry running is avoided (in fluid pumps, for example).
The high heavy metal content makes the alloy unsuitable for use in highly corrosive environments. However, the corrosion resistance is sufficient for most technical purposes – including for open air use. The machining properties are good. The most important areas of application for SILAFONT® - 70 are: pistons for combustion engines, gears, slide bearings, pump parts, wear-resistant and heat-resistant parts of all kinds. |
