Compactinitic 1137

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.
