Abstract

Lighter flints are made by (a) making powders of the different constituent metals; (b) mixing the powders in the desired proportions; (c) compressing the mixt. to form rough billets; (d) sintering the billets, while applying a thermal treatment, simultaneously with or after step (c); (e) cooling each billet, e.g. in an oil bath; (f) reheating the billets and extruding or drawing them to wire; (g) cutting to desired length; and (h) finishing the obtd. flints. Pref. steps (c) and (d) are carried out simultaneously in a press the die of which is heated by induction or the Joule effect. By sintering the rough pressed billets formed, and not simply sintering the powder mixt. (which has been suggested as an alternative to the mfr. of flints by moulding) a superior product is formed which does not deform in use.
