Home Resource Center Product Data and Related Literature Alloys Plastic Tooling Alloys PLASTIC TOOLING ALLOYS Resources Data Sheet - MoldMAX HH MoldMAX® HH (high hard) by Materion Brush Performance Alloys has a hardness and strength competitive with standard tool steels but its thermal conductivity is four to six times higher. MoldMAX® HH is commonly used for injection mold cores and cavities, and blow mold pinch-offs. Data Sheet - MoldMAX LH MoldMAX® LH (low hard) by Materion Brush Performance Alloys is a premium copper mold alloy that provides hardness and strength comparable with standard tool steel, but with higher thermal conductivity. MoldMAX® LH is typically used for injection mold cores and cavities where moderate hardness, high toughness and conductivity are required. Data Sheet - PROtherm PROtherm® (formerly MoldMAX SC®) by Materion Brush Performance Alloys is a high conductivity copper mold alloy with good strength, superior toughness and the highest conductivity of any alloy, while maintaining atensile strength over 100,000 psi. Data Sheet - MoldMAX V MoldMAX® V (MMV) by Materion Brush Performance Alloys is a high conductivity, moderately high strength, copper nickel silicon chromium alloy, used in applications such as injection mold and blow mold cores and cavities. Data Sheet - MoldMAX XL MoldMAX XL® by Materion Brush Performance Alloys is a high strength copper mold alloy with good thermal conductivity, hardness comparable to tool steel, but with superior thermal conductivity. MoldMAX XL® contains no beryllium, machines faster than tool steels and is available in sections as large as 12” thick. Brochure - MoldMAX Plastic Tooling Alloys MoldMAX® products by Materion Brush Performance Alloys are high performance alloys that merge thermal conductivity and strength and are specifically designed for the plastic processing industry. MoldMAX® alloys are used in injection mold components and core / cavity inserts, blow mold pinch offs, neck rings and handles inserts, hot runner system injection nozzles and manifolds. Reprint - A Copper-Nickel-Silicon Chromium Alloy for Mold Tooling High-strength, high conductivity alloys serve a variety of industrial purposes. One innovative new alloy, Copper-nickel-silicon chromium (CNS-V), offers a variety of advantages to the plastics molding industry. Learn about its physical and mechanical properties, including its high thermal conductivity, to better understand CNS-V applications, benefits and limitations when compared with other common mold materials. Reprint-Are Copper Beryllium Alloys Safe? Copper beryllium alloys often are used to make injection mold components that are then used to produce plastic containers. Ongoing concerns about the health hazards associated with beryllium, particularly when it is used in molds that produce articles that come in contact with food, prompted a recent study that concluded that copper beryllium alloys can, in fact, be used safely in molds.
