Fabrication Properties provided by CDA
*Since brazing is performed withing the hot-short range, strain must be avoided during brazing and cooling.
Thermal Properties provided by CDA
*Temperature is measured in Fahrenheit. **For Stress Relief, Solution Treatment and Annealing - Time is measured in hours/inch of thickness. For Precipitation Heat Treatment - Time is measured in hours.
