Effects of specimen width and rolling direction on the mechanical properties of beryllium copper alloyC17200

Abstract

The objective of the research was to study the effects of specimen width and rolling direction of beryllium copper alloy, C17200, on the mechanical properties of yield strength and Young's modulus. The experimental results showed that the reduction of the specimen width from 12.5 mm to 2.5 mm did not affect the yield strength but reduced the Young's modulus by 4%. Also, the change of rolling direction affected both the yield strength and the Young's modulus. When the tension direction is parallel to the rolling direction, the maximum yield strength was obtained. The results can help predict the behavior of small-scale beryllium copper products more accurately.
