Description

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

This material data has been provided by Materion Brush GmbH.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
