Sarrafa karfe (aikin karafa), wani nau'in fasaha ne na sarrafa abubuwa da ayyukan samar da kayayyaki, bangarori da kayan aikin daga kayan karafa.
Ana amfani da sassan ƙarfe a cikin injuna da kayan aiki daban-daban. Partsananan sassa suna da kwanciyar hankali na girma, ƙarfi da tauri, halaye masu ƙarfi da ƙananan yanayin juriya da haɓaka, waɗanda galibi ana amfani dasu don yin sassan daidaito. Idan aka kwatanta da sassan filastik, akwai nau'ikan kayan abubuwa da yawa na sassan karafa, kamar su alloy alloy, alloy steel, zinc alloy, steel, titanium alloy, magnesium alloy, da dai sauransu, tare da kaddarori daban-daban. Daga cikin su, ana amfani da ferroalloy, aluminum alloy, copper alloy da zinc alloy a masana'antar da kayayyakin fararen hula. Wadannan kayan karafa suna da nau'ikan kayan jiki da na sinadarai daban-daban, tsari daban-daban da sifar kayan sarrafa sassan karfe yana da babban bambanci.
Babban hanyoyin sarrafa kayan karafan sune: gyaran inji, buga tambari, gyaran simintin gyare-gyare, aikin karafan foda, gyaran allurar karfe.
Machining shine aiwatar da sauya gabaɗaya girma ko aikin abin aiki ta hanyar nau'in kayan aikin inji. Dangane da bambanci cikin hanyoyin sarrafawa, ana iya raba shi zuwa yankan inji da matsin lamba. Stamping wani nau'in tsari ne na yin tsari wanda yake amfani da latsawa kuma ya mutu don yin amfani da karfi na waje akan takarda, tsiri, bututu da bayanin martaba don samar da nakasar filastik ko rabuwa, don samun sifar da ake buƙata da girman girman aikin (ɓangaren sintiri).
