Introducing ALLVAR Alloy 30 Thermal Compensation Washers for your toughest thermal challenges
At ALLVAR, our goal is to help innovators solve the most demanding thermal challenges. We’re making it easier to tackle the athermalization problem today. ALLVAR Alloy 30 thermal compensation washers are now a commercially-off-the-shelf (COTS) ALLVAR product. These washers are ready to order.
Why ALLVAR Thermal Compensation Washers?
ALLVAR Alloy 30 washers and spacers are a simple solution to thermal mismatches. These constant force load washers:
- Enable smaller, more compact, and lightweight structures
- Eliminate the need for lengthy compliant bolts and flexures.
- Enhance the longevity of your structures
- Reduce concerns related to tight force-load margins due to varying operating temperature
- Achieve more reliable joints for your applications.
Washer Size and Availability
Our initial selection of COTS negative CTE constant force washers includes sizes #2, #4, #6, and #8 washers. These chosen from the most requested sizes. The ALLVAR team is ready to help with your specific design if you need custom thickness spacers or other washer sizes.
Applications for Thermal Compensation Washers
Our ALLVAR constant force load washers are tackling CTE mismatches across many industries. These include aerospace, energy, automotive, defense, medical, optics, academia, applied physics, and beyond.
Why choose negative thermal expansion ALLVAR Alloy 30?
ALLVAR Alloy 30 has exceptional properties:
- Negative axial Coefficient of Thermal Expansion of -30.0ppm/°C at room temperature.
- Positive CTE in the radial direction, comparable to Aluminum.
- Stabilizes mechanical force by compensating for expansion or contraction mismatches.
- Exhibits mechanical and material properties like other titanium alloys
