These found very wide application in the hermetic compressors which are used in white goods like AC, fridge, Coolers. Sintering is the best method to do such parts with high accuracy, consistency & at low cost. This allows to make parts with minimum machining. These parts are steam treated. Which increases its corrosion resistance, increase its density & strength. And main advantage is that these are gas leak proof. Which is the main requirement for hermetic compressor parts.
