Tenbloc is a precision pressed and sintered block which is manufactured using special powder metallurgical techniques which give complete flexibility for in the mold inoculation of both ductile and gray irons.
A number of different compositions are available and these have been shown to be effective in the elimination of carbides in thin sections and reduction in micro-shrinkage as well as achieving the normal metallurgical requirements for ductile and gray irons.
