If the answer is Lynite Lo-Ex Pistons and an Alcoa Aluminum Cylinder Head on the motor, you are buying auto mobile performance with a capital P. The keys to that answer are lightness and heat conductivity, two fundamental ad vantages of Aluminum. You drive faster, farther, these days. You call on your motor to turn over as fast as 4,000 revo lutions per minute. That punishes bearings! Light Aluminum Pistons decrease that punishment, increase bearing life. They give you flashing acceleration, and a smooth, responsive motor. Lynite Lo-Ex Piston refinements, including the famous T-Slot design, and scuff-resisting Alumilite finish, represent the greatest advance in the piston art. Aluminum Cylinder Heads, because of the metal's superior thermal conductivity, elimi nate dangerous hot spots, and actually increase power from 5 to 15%, with lower operatingcosts. If lightness in moving pistons makes the motor of your car operate better, what about lightness in your own product, your own equip. ment? Likewise, the superior heat conductivity of Aluminum may work the same wonders in your processes that it does in cylinder heads. Nature made Aluminum light. Research made it strong, and versatile, and economical for you to use. Our engineers are available for consultation. ALUMINUM COMPANY OF AMERICA 1899 Gulf Building, Pittsburgh, Pa.
