U-W uthetha ukubhala, ukuphosa;
Intsimbi yekhabhoni ye-C-CARBON, u-A, u-b, kunye no-C zibonisa ixabiso lamandla ohlobo lwentsimbi ukusuka kwesezantsi ukuya kwephezulu.
I-WCA, i-WCB, i-WCC imele intsimbi yekhabhoni, esebenza kakuhle ekudibaniseni nasekuqineni koomatshini. I-ABC imele inqanaba lamandla, i-WCB esetyenziswa rhoqo. Izinto zombhobho ezihambelana ne-WCB kufuneka zibe yi-A106B, kwaye izinto zokubumba ezihambelanayo yi-A105. Zifanelekile kwiivalvu phantsi kobushushu obuqhelekileyo kunye noxinzelelo.
I-WC6 yindlela yokubumba eyenziwe ngentsimbi ye-alloy. Ineempawu ezibalaseleyo zokumelana nobushushu obuphezulu kunye ne-antioxidant kwaye ifanelekile kwiivalvu phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu.
Izinto zombhobho ezihambelanayo zimalunga ne-A355 P11, kwaye inxalenye yokubumba yi-A182 F11;
Ukongeza, kukho i-WC9, intsimbi ye-alloy enobushushu obuphezulu, ehambelana ne-A355 P22, kwaye i-forging kufuneka ihambelane ne-A182 F22.
I-WC welded casting inamandla aphezulu kwaye ilukhuni. Ifanelekile ukusetyenziswa kwemizi-mveliso eqhelekileyo.
I-LCB/LCC (ASTM A352) Intsimbi yekhabhoni enobushushu obuphantsi inobunzima obuphantsi kunye nokumelana nokugqwala. Ifanelekile kwiindlela zokusetyenziswa kobushushu obuphantsi, njengegesi yendalo ye-LPG (LNG).
Iivalvu zeZfa zivelisa iivalvu zebhabhathane zeWCB eziqhelekileyo kubathengi kwihlabathi liphela abanobushushu obuqhelekileyo, kwaye singavelisa iivalvu zebhabhathane zeLCC kubathengi abavela eMntla Yurophu njengaseRashiya, eFinland njl.
ngasentla yiWCBivalvu yebhabhathane ye-wafer yaseTshayinakunye ne-LCCIbhabhathane eliyi-lug yaseTshayinaivalvu.
