Unique Applications and Advantages of VMP Solders and Brazes

Heat Treatable Brazes

Traditional brazes will melt if reheated. As a result, once brazed, a part cannot be subjected to high temperatures, for fear of damage to the joint.

But VMP's brazes throw "traditional" ideas out the window! They allow brazing at temperatures lower than the solutionizing temperature for the parent metal, ensuring that assembly and machining can be completed in the soft state. Subsequent heat treating can deliver excellent material properties to the brazed part, but the VMP effect ensures that the brazed joint is stable throughout the brazing process.

Design Freedom

Traditional joining methods limit the designer by imposing temperature restrictions:

  • The parent material must remain stable through the process, limiting the process temperature.
  • The joint must be stable in the service environment, limiting the safe service window.
  • When multiple joining steps are needed, different solder or braze alloys must be used, at successively lower temperatures, to ensure that existing joints are not damaged on subsequent steps.

All of these limit the design, and the functionality, of today's complex parts.

But with VMP solders and brazes, these concerns are a thing of the past. Process and service temperatures are decoupled from the properties of the joining materials. The Variable Melting Point effect ensures that the same alloy can be used in each stage of a multi-step process. It also ensures that service conditions are not impacted by a low-temp joining process, enabling the use of exotic, temperature sensitive materials. VMP solution offer unparalleled design freedom, making them a designer's best friend.

Reduced Emissions and Lower Energy Consumption for a Greener World

Fuel consumed in gas-fired heat treatment and brazing ovens is a major source of industrial emissions. By reducing oven temperatures, greenhouse gas emissions and fuel consumption can be drastically reduced. By adopting a VMP joining solution, our customers can operate their furnaces at lower temperatures, without sacrificing the performance and quality of their joints in service. This leads to reduced emissions, reduced costs, and higher efficiencies. And that leads to a greener world.
