Description

Materion Performance Alloys’ QMet 300 strip is a high-performance, heat treated copper alloy designed to provide very high electrical and thermal conductivity while still retaining moderate strength. This non beryllium-containing alloy is idea for heat spreading structural components in consumer electronic devices as well as high reliability, high power electrical and electronic connectors.

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.
