MOLDMAX XL bar

1. MOLDMAX XL
MoldMAX XL is a high strength copper mold alloy with good thermal conductivity. MoldMAX XL contains no beryllium and is avaiable in sections as large as 12 thick. The alloy hardness is comparable with AISI P - 20 tool steel, but its thermal conductivity is two to three times higher.
MoldMAX XL is used as injection mold cores and cavities. The alloy provides excellent toughness, wear resistance and surface finish. MoldMAX XL typically machines faster than tool steels, and with appropriate machine tools, metal removal rates several times higher can be obtained.

USES AND APPLICATIONS
MoldMAX XL is commonly used for injection mold cores and cavities, as well as pinch-offs for blow molds.
SPECIFICATIONS AND STANDARDS
MoldMAX XL is certified to hardness and conductivity only.
MoldMAX resists abrasive wear and galling, exhibiting excellent wear resistance when used for injection mold components and cavity inserts in direct contact with plastic parts in the injection molding process. | MoldMax improves parting line maintenance in the blow molding process. In addition, it provides longer service life when used for components and inserts in aluminum blow molds. |
