Description

The alloy is used for pieces with very small expansion, for lens masks, antennas, parts for general measurement technology, as well as for bimetals (according to DIN 1715). The break point temperature (temperature at which a break point in the expansion-temperature-curve occurs) is 230 degrees C. The material has extremely low thermal expansion at 100 degrees C. The cupping index at 1mm thickness is 9.5mm.

Equivalent Materials

This material data has been provided by WIAM.

"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.
