We offer Silver Brazing Alloys:

 

Key words :Silver Cadmium Bearing,Silver Phosphor Copper,Silver Flux-coated Brazing Alloys 

We ,IREE offer alloys that are vacuum-grade (vtg) primarily used in aero-engine, medical, or extreme conditions where braze integrity is critical. These alloys are brazed in high-purity atmospheres and can be inspected (x-ray) for joint integrity. All alloys are certified with actual chemistries and are formed with vacuum-cast ingots to insure the highest quality.
Forms

• Fine wires – ranging from 0.001” (0.0254Mm) – .125” (3.175Mm) in diameter
• Rods – fine wires cut to length ranging 0.02” (0.0508Mm) – up to 7 feet (2.133 Meters)
• Foil – continuous rolled strip
  • Thickness: 0.0005” (0.0127Mm) – 0.150: (3.81Mm)
  • Width: 0.015” (0.381Mm) – 8” (200mm)
• Powder – most (if not all) alloys can be provided in powder form.
  • Common mesh sizes: -140, -140c, -325
• Paste – brazing paste is powder suspended in an organic binder with controlled viscosity (thickness) for both manual and automated applications.
• Preforms – our brazing filler metals can be made into infinite amounts of preformed shapes and sizes, including but not limited to:
  • Wire rings
  • Stamped washers
  • Shims
  • Micro machined

Silver Brazing Alloy-Foils 

Silver brazing filler metals have low melting point, good wettability and filling performances. They also have features of high mechanical strength, fine plasticity, electrical conductivity and corrosion resistance.

 

The filler metals are used in the brazing of stainless steel, carbon steel, hard alloys, copper and copper alloys, etc. In order to meet some specific needs in the brazing process, indium, tin or nickel can be added to compose quaternary alloys or complex alloys. Flux is usually applied to achieve the desired joints.
