Our History

2011
ALLVAR Alloys Discovered
Negative Thermal Expansion Discovered

Dr. James Monroe discovers negative coefficient of thermal expansion alloys as a graduate researcher. 

2013
NSF I-Corps

Dr. Monroe takes part in the National Science Foundation's "business boot camp for scientists" to determine if there is a market need for negative thermal expansion materials.

2014
ALLVAR is Founded

ALLVAR is founded to ensure negative thermal expansion alloys evolve from a scientific novelty sitting on the lab bench to useful technology for society.

2015
NSF SBIR Phase I
High Temperature Negative CTE Discovered

Multiple candidate materials are explored to see if they are worth pursuing. ALLVAR Alloy 30 is selected and developed.

2016
Product Market Fit

ALLVAR discovers a product market
fit for athermalization of optics at
SPIE Photonics West in January 2016.

NSF SBIR Phase II

ALLVAR Alloys are scaled from small pieces of material to round bar and tube for optics applications.

2018
First Commercial Sales
Negative thermal expansion round bar and tube for athermalization and achieving a tuned zero thermal expansion.

ALLVAR Alloys officially enters the market with its first sale.

NSF TECP (Technology Enhancement for Commercial Partnerships) ALLVAR works with expert optical designers to create the first ALLVAR enabled athermal optic proof of concept.

NASA SBIR Phase I
ALLVAR begins characterizing the long-term stability of ALLVAR Alloys in preparation for studying the use of ultra-stable struts.

2019
NASA SBIR Phase II
Zero thermal expansion metering structures for telescopes can be achieved using negative thermal expansion ALLVAR Alloys. This prototype was built during a NASA SBIR Phase II.

ALLVAR enabled ultra-stable
struts are created in collaboration with Quartus Engineering and the University of Florida LIGO research group.

2020
NASA SBIR Phase I for High Temperature Negative Thermal Expansion
Negative thermal expansion alloys enable zero thermal expansion and tuned thermal expansion for athermalization of optics and precision products.

ALLVAR develops a high temperature negative thermal expansion alloy - ALLVAR Alloy HT. 

Although not yet commercially available, ALLVAR Alloy HT raises the upper operating temperature of ALLVAR Alloys to 250°C.

2021
NASA SBIR Phase I Award for Scaling Athermal Struts to Meter Lengths
Ultra Stable struts with zero thermal expansion created using negative thermal expansion ALLVAR..

ALLVAR works to scale ALLVAR Alloy athermal struts to meter+ lengths capable of supporting large telescopes and metering structures. 

2022 and Beyond
There are more discoveries to make.
Negative Thermal Expansion ALLVAR Alloys; IT'S POSSIBLE

In the hands of innovative researchers, designers, and engineers, ALLVAR Negative CTE Alloys are enabling novel, smaller, lighter, and more reliable designs in optics, cryogenics, scientific instrumentation, and other industries. 

We do not know what else the future may hold for ALLVAR Alloys, but we do know that after 10 years we feel stronger than ever that negative CTE alloys are much more than a scientific novelty.
