I am working on design of mold, for gravity die (permanent mold) casting.
I know this technic is used for low temperature alloys but in my case the
pooring temp. is around of 1500 °C it is as Ni base super alloy.
I would like to use this mold at least 100 times or more.
What kind of material could be suitable for this application
I saw, some of them are using cast iron ?
I heard also some copper alloys could be suitable due to high thermal
One of them suggested me Tungsten alloys but i have no idea about the life
time, it cost high as material and as machining
What about the some steel grade ?
Any other material to suggest me ? Is ther any ceramic or composite
materials suitable for permanent molds
