  ISO 1083 JS 450-10 Ductile Cast Iron  
 

ISO 1083 JS 450-10 ductile cast iron has the characteristics of good strength, very high ductility even at low temperatures and good machinability.

Our Dandong Foundry normally use ISO 1083/JS/450-10 ductile cast iron to produce exhaust manifolds, dental chair brackets, cradle brackets, gas valve parts, gas compressor parts, security parts for low temperature applications, etc.
