Tá friotachas meánach ag sreang PTC Alloy agus comhéifeacht friotaíochta teocht ard dearfach. Úsáidtear go forleathan i téitheoirí éagsúla. Is féidir leis an teocht a rialú go huathoibríoch agus an chumhacht a choigeartú trí shreabhadh leanúnach a choinneáil agus sruth a theorannú. Tá go leor buntáistí ag cóimhiotal PTC, mar shampla rialú teochta uathoibríoch, rialú uathoibríoch cumhachta, sruth leanúnach, teorannú reatha, coigilt fuinnimh agus saol praiticiúil fada.
Is féidir linn go leor cineálacha sreang friotaíochta PTC a tháirgeadh. Glaonn roinnt cliant sreanga NiFe in ionad sreanga PTC.
