To whomever this may concern,

My name is Mike Oliver, I work for Alcoa at 1he lntalco plant in Ferndale Washington. I am currently the Casthouse Technical Coordinator and have 30 years of experience in casting. We cast 18 million pounds of Air-Slip Billet in diameters 6" to 12" each month, most of which is in the 7" to 1 0" range.

As you probably know Pyrotek has had most of the market for producing and selling Transition Plates for Wagstaffs Air-Slip and is the OEM transition plate. For the last 7-8 years other suppliers have tried to produce a Transition Plate

to compete with Pyrotek. I have trialed most of these products, some performed OK but none as well as Pyrotek's N-17. Until now! The recently developed UlTRA TEMP-AL has surpassed N-17 inperformance trials. Plates installed in our 8" billet unit were in service for just over 400 drops, this means this one t-plate had over 500,000 lbs pass through it! The mold that which this t-plate was in was removed because the graphite was in need of replacement, when we

inspected the plate it was still in excellent condition. We have since trialed these t-plates in our 7", 9" and 10" tables with similar results. Recently we decided to switch from using Pyrotek's N-17 to this very good performing and competitively priced ULTRA TEMP® Al Transition Plate. These plates are now a Warehouse stock item here at lntalco. I encourage you to try some you will be very pleased with the results!
