Prior to that in the 1950s, Wall Colmonoy invented Nicrobraz® nickel-based brazing filler metal and pioneered high temperature furnace brazing. Even today, Nicrobraz® is used extensively in heat exchanger manufacture and overhaul. Wall Colmonoy Aerobraze continues to develop its brazing and manufacturing expertise resulting in increased efficiencies, significant cost savings and performance improvements. ![F16_Nicrobraz-130-1](https://metals.wallcolmonoy.com/hs-fs/hubfs/F16_Nicrobraz-130-1.png?width=605&name=F16_Nicrobraz-130-1.png) [![REQUEST FOR QUOTE](https://no-cache.hubspot.com/cta/default/5229633/279f7eef-6a44-4a8b-aaf5-e2d13e5b6caf.png)](https://cta-redirect.hubspot.com/cta/redirect/5229633/279f7eef-6a44-4a8b-aaf5-e2d13e5b6caf)   **CONTACT** [Oklahoma City](https://metals.wallcolmonoy.com/products-capabilities/aerobraze-oklahoma-city?hsLang=en) 4700 SE 59th | Oklahoma City, OK 73135 E: [aet@wallcolmonoy.com](mailto:aet@wallcolmonoy.com) T: 405-672-1361 #### [Products & Capabilities](https://www.wallcolmonoy.com/products-capabilities/) - [Surfacing Alloys](https://www.wallcolmonoy.com/products-capabilities/surfacing-alloys/) - [Brazing Alloys](https://www.wallcolmonoy.com/products-capabilities/brazing-alloys/) - [Precision Components](https://www.wallcolmonoy.com/products-capabilities/precision-components/) - [Aerobraze](https://www.wallcolmonoy.com/products-capabilities/aerobraze-engineered-technologies/) - [Nicrocraft™](https://www.nicrocraft.com/) #### [Company Profile](https://www.wallcolmonoy.com/company-profile/) - [Who We Are](https://www.wallcolmonoy.com/company-profile/who-we-are/) - [What Sets Us Apart](https://www.wallcolmonoy.com/company-profile/what-sets-us-apart/) - [Vision & Values](https://www.wallcolmonoy.com/company-profile/vision-values/) - [Origin of Our Name](https://www.wallcolmonoy.com/company-profile/origin-of-our-name/) - [News & Events](https://news.wallcolmonoy.com/) #### [Contact](https://www.wallcolmonoy.com/contact/) - [Locations](https://www.wallcolmonoy.com/contact/locations/) - [Request a Quote](https://www.wallcolmonoy.com/technical-requests/) - [Technical Center](https://metals.wallcolmonoy.com/technical-center/) - [Careers](https://www.wallcolmonoy.com/contact/careers/) - [Newsletter Sign-up](https://www.wallcolmonoy.com/contact/newsletter-sign-up/) - [Certificates & Approvals](https://www.wallcolmonoy.com/contact/downloadcertsapprovals/) #### Connect With US - - - - [Contact US](https://www.wallcolmonoy.com/contact/) - [© 2023 Wall Colmonoy](http://www.franklinbronze.com/) - [Terms of Use](https://www.wallcolmonoy.com/terms-of-use/) - [Cookie Policy](https://www.wallcolmonoy.com/cookie-policy/) - [Privacy Policy](https://www.wallcolmonoy.com/privacy-policy)
