Aluminum Alloy 6951



Aluminum Alloy 6951 is predominantly used to manufacture fins for heat exchangers in the aerospace market. Since 6951 is a heat treatable alloy, it provides additional strength to the fins while increasing sag resistance.


This additional strength also allows the manufacturer to reduce the gauge and subsequent weight of the formed fin. Due to these important attributes, aluminum alloy 6951 is the preferred alloy for heat transfer units manufactured for the aerospace industry.

Lynch Metals has the largest inventory of 6951 coil in the world. By stocking wide width coils in a multitude of gauges, Lynch will slit to your specific width and quantity within three to five days from order placement.

Whether you require one pound or ten thousand pounds, Lynch Metals will provide you with the quantity you require when you need it.

Since this material is stocked in “O” temper in gauges as light .003” and as heavy as .015,” Lynch Metals has invested in special slitting equipment to insure a burr free, tight, uniform coil. Our three Goebel slitters, along with our two Ruesch slitters and our high production Kampf slitter, were specifically purchased to slit this unique product.

Lynch Metals takes extra precaution when packaging your slit coil so you receive it in perfect condition. Our sophisticated foam packaging equipment provides a protective outer shell that fully encompasses the slit coil packed within a heavy duty cardboard box. Material is easily identified with your part number by our computerized labeling system.
