Pre-sintered Preforms (PSPs) are a sintered powder metallurgy product composed of a homogeneous mixture of a superalloy base material and braze alloy powders. Typical superalloy content ranges from 40 to 70% and plate thickness ranges from 0.3mm (.010”) to 5mm (.200”). Custom preforms can be cut from a sintered plate, tack welded to a component and vacuum brazed.
Aimtek manufactures a complete line pre-sintered brazing preforms (PSP) for turbine component restoration and repair. Custom engineered blends and shapes, and application support.
For brazing to concave surfaces, curved PSP’s are recommended.
Unlike flat preforms, curved PSPs eliminate the need for a second braze cycle on both convex and concave surfaces reducing processing time.
