Unobtanium Has Arrived!

By: Amy Zelazny

Do you have a problem maintaining the performance and structural integrity of your opto-mechanical design over a wide temperature range? Would a material with little or even negative CTE solve this problem?

We can help: ALLVAR Alloy 30, offered by ALLVAR Alloys:

  • Has a longitudinal Coefficient of Thermal Expansion of -30.0ppm/°C
  • Has a positive CTE in the radial direction (similar in magnitude to Aluminum), allowing for compliant mounting of optical elements
  • Exhibits many of the properties of Titanium
    • Alloy 30 can be machined like any other metal, tolerances of 0.001” are easily achievable
    • Just as with Aluminum, Alloy 30 can be anodized to provide maximum control of stray light within your lens assembly and optical system
  • Is offered in both round bar and tube formats. It is a natural fit for the design and fabrication of lens stack spacers, lens barrels, and lens to focal plane stand-offs.

The inclusion of ALLVAR Alloy 30 in your next opto-mechanical design can lead to:

  • Lower optical element count due to successful passive mechanical athermalization
  • Simplified mechanical geometry leading to weight savings
  • Reduced complexity and cost throughout your supply chain and manufacturing process

Specifically targeting fixed-focus LWIR objectives/cameras, the addition of ALLVAR Alloy 30 can eliminate nested barrel structures and complex compensation mechanisms, providing passive mechanical athermalization for maintenance of optimum image quality from -40°C to +70°C and beyond.

Don’t miss out on an opportunity to use an exciting new material that will increase the efficiency of your opto-mechanical design cycle, contact ALLVAR Alloys today.

ALLVAR wins NASA SBIR Phase II award

ALLVAR alloys has been awarded a NASA Small Business Innovative Research Phase II grant for “Ultra-stable ALLVAR Alloy Strut Development for Space Telescopes.”

This NASA SBIR Phase II proposal was in response to the need for Ultra-Stable Telescope Structures and is designed to evaluate ALLVAR Alloys for their potential as metering and support structures for optics that are critical to NASA’s future missions. Telescopes used for astrophysics, exoplanet, and planetary studies require picometer stability over several minutes to hours. Building large support structures with picometer level stability is a challenge with currently available materials due to their brittle nature in the case of Zerodur and ULE or their requirement to have tight thermal control in the case of SiC or carbon fiber composites. ALLVAR Alloys offer a new material solution for thermally stable structures. They exhibit negative thermal expansion and can compensate for the positive thermal expansion of other materials to stabilize a telescope

Website Redesign

A lot has happened at ALLVAR in just a short time! While we’ve been continuously striving towards prototype development, the team realized that the old website needed a complete overhaul. After a little practice, we were able to put together a new site that better tells about our revolutionary negative thermal expansion metal and the team behind it.

We hope you enjoy the new site!

ALLVAR secures NSF SBIR Phase II award

The National Science Foundation (NSF) has awarded ALLVAR with a Small Business Innovative Research Phase II grant. The intellectual merit of this project lies in a new method to exhibit unprecedented control over thermal expansion properties in metal alloys.

The discovery of the tailoring effect or “programmed” thermal expansion of a bulk metal to match that of other common materials (metals, polymers, and ceramics) will change the way scientists and engineers design for thermal compensation. These alloys can also be tailored not to expand or contract with temperature changes and even be made to shrink when heated.

The total awarded amount of the NSF SBIR Phase II is $750,000.

 

ALLVAR wins 3rd Place at 2015 Texas New Ventures Competition

Dr. James Monroe secured a Third Place win for his pitch at the first annual Texas A&M New Ventures Competition. The competition, by Texas A&M Engineering Experiment Station and the Texas A&M University System, promotes the commercialization of emerging technology and recognizes companies with high-growth potential.

Thank you to Texas A&M University and Texas A&M Engineering for setting up a great event. As third place prize, ALLVAR secured $50,000 in non-dilutive funding.
