Intshayelelo yeMveliso

Izinto ezisetyenziswa kwisakhelo se-lead zihlala zenziwe nge-alloy yobhedu, i-Iron kunye ne-phosphorus, okanye i-copper, i-nickel kunye ne-silicon, ezine-alloy eqhelekileyo ye-C192(KFC), i-C194 kunye ne-C7025. Ezi alloys zinamandla aphezulu kunye nokusebenza kakuhle. I-C194 kunye ne-KFC zimela kakhulu i-alloy yobhedu, i-iron kunye ne-phosphorus, zezona zinto zixhaphakileyo ze-alloy.

I-C7025 yi-alloy yobhedu kunye ne-phosphorus, i-silicon. Inomoya ophezulu wokushisa kunye nokuguquguquka okuphezulu, kwaye ayidingi unyango lobushushu, kwaye kulula ukuyinyathela. Inamandla aphezulu, iipropati ezibalaseleyo zomoya wokushisa, kwaye ifanelekile kakhulu kwizakhelo ze-lead, ngakumbi ekuhlanganiseni iisekethe ezidityanisiweyo ezinoxinano oluphezulu.
