O mea fa'apipi'i faufale e maualuga-malosi fa'apipi'i (malosi fa'amalosi > 65 MPa, uamea-i-u'amea fa'amau fa'amalosi malosi > 30 MPa, malosi fa'asili > 18 MPa), e mafai ona tatalia uta mamafa, ma fa'asalaina i le matua, vaivai, ma le pala. Latou te faʻaalia le faʻatinoina o le faʻatinoga i le taimi atoa o loʻo faʻamoemoeina le olaga ma e talafeagai mo le faʻapipiʻiina o vaega faʻavae e faʻatatau i malosiaga maualuga.
O mea fa'apipi'i le -fa'avae e maualalo le malosi ma e le lelei le mautu, ma e mafai ona fa'aoga mo le fa'apipi'i masani, fa'amaufa'ailoga, ma fa'amau; e le mafai ona faʻaaogaina mo le faʻapipiʻiina o vaega faʻavae.
O mea fa'apipi'i faufale e maualuga-malosi, pa'u-tete'e, a'afiaga-ma faigofie ona fa'aoga. O lo'o fa'aaogaina mo le fa'apipi'iina o mea fa'atusa pe 'ese'ese e pei o metala, sima, palasitika, pa'u, ma fafie. E mafai ona latou sui vaega o auala feso'ota'iga masani e pei ole uelo, fa'asa'o, ma fa'amau. O le fa'asoaina fa'amamafa i luga o le mea fa'apipi'i e tutusa, e leai se vevela-a'afia sone po'o se suiga o vaega.
O mea faʻapipiʻi faʻapipiʻi e faʻaaogaina lautele i le inisinia, muamua mo le faʻamalosia, taula, faʻapipiʻi, ma le toe faʻaleleia o vaega; e pei ole u'amea fa'apipi'i, fa'apipi'i alava kaponi, fa'apipi'i fa'amau, fa'amalosia ta'eta'ei ma fa'amaufa'ailogaina, toe fa'aleleia o pu, fa'apipi'i o le auala, puipuiga o luga, ma fa'amau sima.
