Introducing the Next Generation of Almen Strips
Numbered Almen Strips with Coverage Check Finish
The Almen strip hasn’t changed significantly since its development in the 1940s by John Almen. Year after year, the deceptively simple test coupon fulfilled its function as an indicator of shot peening intensity. Shot peening was growing increasingly sophisticated; however, mostly due to its contribution to the aerospace industry. Electronics Inc. (EI) recognized this and has developed an Almen strip with features to help peening facilities meet the demands for increased process and quality control.
