Compactinitic 1137 is a material, that has corrosion resistance in an extend so the parts can be used in a humid and slight acrid environment. Similiar passive resistance chrome oxide film as in stainless steels It can be easily machined It as a low thermal expansion and a high heat conductance (Cu share?) Excellant sound dampening properties Austenitic Grade with a vermicular graphite form created and developed by Lee Shepherd at Vanguard Foundry The material does not follow or have a designated standard. Instead the alloy is a hybrid utilising the properties of austenitic irons It also is made by balancing the sulphur and magnesium levels to produce a compacted graphite form. Compactinitic was developed in conjunction with a German pump housing manufacturer requesting a material to compete with stainless steels with a lower cost associated The austenitic matrix is developed by a nickel content being above 10% The chrome level is above 3% The foundry is currently trying to develop the material as a suitable alternative for Turbo charger housings which are currently produced using Simo and D5s materials.
