What are special alloys?

Special alloys are technically advanced metal mixtures that are designed for special requirements such as high temperature resistance, extreme corrosion resistance, maximum mechanical loads or special magnetic properties. They are used wherever standard materials such as steel or aluminium are not suitable. Aluminium reach their limits - for example in aviation, the chemical industry, medical technology or Rubber-metal composite parts under extreme conditions.

 

Properties of special alloys

In contrast to standard alloys, special alloys often consist of several alloying elements in a precisely harmonised composition. Typical properties can be

  • High temperature resistance (e.g. >600°C)
  • Corrosion and acid-resistant properties
  • Biocompatibility (e.g. for implants)
  • Magnetic or non-magnetic design
  • High strength with low weight

 

Examples of special alloys:

  • Titanium alloys (e.g. Ti-6Al-4V)
  • Nickel-based alloys (e.g. Inconel®, Hastelloy®)
  • Cobalt-based alloys (e.g. Stellite®)
  • Duplex or super duplex stainless steels

 

Application of special alloys

  • Rubber-metal composite parts For extreme temperatures or aggressive media
  • Chemical and process engineering systems
  • Aerospace (e.g. engine parts, structural elements)
  • Medical technology (e.g. bone plates, surgical instruments)
  • Energy and environmental technology, offshore systems, heat exchangers

 

The combination with elastomers such as FKM or HNBR enables durable, dense and thermally resilient hybrid components.
