CDA 521

Product Overview

CDA 521 is a copper-tin braze alloy used on steel where brazing temperatures lower than pure copper are needed. It is best suited for the economical brazing of components that will be used in the HVAC or automotive industries or where other steel and copper connections are needed for furnace brazing applications. Due to its higher temperature, CDA 521 is prone to longer cycle times compared to standard silver braze alloys.
  • Economical
  • Can bridge gaps

    • Typical Industry Applications:

    Compressors, filter dryers
