PREMABRAZE 409

Product Overview

Premabraze 409 is a modified gold-copper alloy that includes a small addition of nickel. This nickel addition renders the alloy somewhat sluggish when molten, but it helps improve wetting on ferrous materials. Premabraze 409 also offers improved ductility over standard gold-copper alloys.
  • Ductile, low vapor pressure alloy
  • Somewhat sluggish flow
  • High purity

Typical Industry Applications:

Vacuum tube components, thin wall tubing
