Diamond standard A
s hard as diamond, durable against abrasion, immune to corrosion and resilient to
thermal shock and impact – SICcast components are made from a silicon carbide and binding agent compound in a mineral casting process and achieve their impressive properties thanks to the hot curing process. Typical SICcast products include pump housings and impellers, nozzles, cyclones and reducer elements for pipes. Pump manufacturers are often faced with the challenge that wetted components – such as the housing and impeller – have to meet strict demands in terms of corrosion and abrasion. In certain industries the pumps convey highly corrosive media, while the wetted components are also bombarded with abrasive particles (e.g. sand) in other fields of application, such as the mining industry.
Over 25 years ago, the Duechting
Group developed a new material for meeting these challenges. SICcast EP135 is a silicon carbide (SiC) with a Mohs hardness of 9.7 (diamond has a Mohs hardness of 10) that is bonded using a special hot-curing epoxy resin. The material is free from
metal, highly chemical resistant,
unfavourable conditions and when using abrasive and corrosive media. Due to the chemical bonding of
non-magnetic and has hardness comparable to diamond. Wear on components made from SICcast EP135 is thus extremely low, even in
the epoxy resin, the material is highly ductile and is thus also resistant to thermal shock and impacts. It also helps to reduce noise and vibrations, which is particularly beneficial when used in pump components, for example. The temperature-controlled, unpressurised casting process means that extremely low shrinkage levels and a correspondingly high degree of dimensional accuracy can be achieved. Moreover, SICcast Mineralguss, a Duechting Group company, also manufactures customised parts made from mineral castings for various clients.
