Duraloy Technologies has been producing High Temperature Alloys for over 90 years. National Alloys, which was acquired and incorporated into Duraloy, invented the alloys that have become industry standards. These alloys include the proprietary grades of heat resistant alloys 22H®, Super 22H®, MO-RE® 1, and MO-RE® 2. Duraloy was the first company to modify the ACI grade HP by adding tungsten to create the now widely used HP+W alloy.

With the addition of the technology and alloys that came with the acquisition of Electroalloys into Duraloy Technologies, we offer well known heat resistant alloys such as Supertherm®, and the TMA® family of heat resistant microalloys.

Duraloy regularly produces all of the ACI corrosion and heat-resistant alloys, as well as a series of proprietary alloys that have enhanced high temperature properties.
