FIN/255 ™, A New High Strength Finstock for Light Weight Heat Exchangers

A new aluminum alloy has been developed which, by virtue of its ultra-fine grain size, has a yield strength capability up to 18 ksi, with formability equivalent to fully annealed AA-1100-0 material.

The new alloy has been particularly suited to the development of a new plate finstock alloy, FIN/255 ™, registered as AA-8007, which can be used to reduce fin gages in fin and tube heat exchangers by up to approximately 20% thereby permitting cost and weight savings.
