Yuav ua li cas cov engineers ntsib thaum tsim manganese hlau alloys?

Engineers feem ntau tawm tsam kom sib npaug ntawm lub zog, tus nqi, thiab kav ntev. Lawv siv cov cuab yeej tshiab xws li kev kawm tshuab los nrhiav cov khoom sib xyaw zoo tshaj plaws. Kev sim thiab kho cov alloy yuav siv sij hawm thiab ua tib zoo npaj.
