Material Notes:
Description: moldMAX® and PROtherm® are Brush Wellman's copper beryllium alloys specifically designed for the plastic processing industry. These alloys provide a combination of thermal conductivity and strength, which allow for :Shorter cycle times and reduced part costsImproved part quality leading to a substantially lower scrap rate3 times faster machining rates resulting in lower cost molds and shorter delivery timesProcessing that is similar to tool steels with no substantial processing changes requiredOne million + cycles leading to lower maintenance costsA reduction in cost for MoldmakersReduced cost and high part quality at a lower piece price for MoldersmoldMAX® provides strength and wear resistance similar to that of many tool steels, and a thermal conductivity that is three to four times greater than steel and comparable to aluminum. moldMAX® is typically specified for full cavity and core inserts, blow mold pinch offs, neck rings and handle inserts; cavity and core sub inserts; injection mold components; and hot runner system injection nozzles and manifolds. Information supplied by Brush Wellman Engineered Materials.Brush Engineered Materials Inc. changed its name to Materion Corporation in March 2011.
