We produce High Temperature Superalloy Castings Parts with investment process centrifugal cast
process and resin sand cast process.
We melt good quality Co-based Alloy Castings with Vacuum Furnaces and Induction Furnaces.
We can cast and machine the hard Cobalt-based Alloy Castings as per the drawings.
We would like to help select suitable Co-based Alloy Grade as per your specific working condition.
Cobalt-based alloys have been in use for producing various components such as vanes or combustion
chambers. The material can be implemented as wrought or as precision-cast parts or as centrifugal
cast parts. The design of cobalt superalloys, which is aimed at an enhancement of both their oxidation
resistance and their hot corrosion resistance, has received considerable impetus recently, especially
since the advent of overlay coating techniques and the extensive studies which have been undertaken
to elucidate the hot corrosion mechanisms and the effect of alloying elements.
