Our recently perfected recovery process eliminates waste of INDIUM in plating baths by conserving the excess INDIUM residue. INDIUM is t o d a y more practical, economical, and efficient than ever before. USE INDIUM IN YOUR PRODUCT—with nonferrous metals a n d a l l o y s — t o minimize wear, corrosion, t a r n i s h — t o provide greater tensile strength, improved ductility, a n d resistance to fatigue a n d friction. FULL EXPLANATION of our recovery technique a n d complete information of INDIUM'S usefulness to Industry will be sent upon request. Just drop a card to our New York Office. /
