Where can I learn more about your alloys?
You can start by visiting our FAQ page and our Resources Page for in-depth articles on various applications, learning videos, and articles about ALLVAR Alloys. We have coined this portion of the site ALLVAR University because we aim to help individuals learn how to use and design with these innovative Alloys
For application specific information, please see the dropdown options under technologies. In this area, you can learn the basics of ALLVAR Alloys spacers for optics, ultra-stable struts, and constant force load washers. Links to additional reading and videos is given for each application.
You can also find more information on ALLVAR Alloy 30’s matweb.com page or read published SPIE proceedings on SPIE’s Digital Library.
