Xuper 65 Cadmium-free brazing alloy

Xuper 65

Cadmium-free, overheating-resistant, free-flowing, capillary-active, ternary silver brazing alloy. For high-strength and ductile joints. Especially for dynamic high-pressure loads in the HVACR sector.

Can be used for brazing joints with operating temperatures from –200°C to 200°C.

Technical data

Brazing alloy
ISO 17672: ~Ag 235

Flux coating

DIN EN 1045: FH 10

Sol./Liq. [°C]: 700 - 740

Tensile strength [MPa]: 535

Density [g/cm³]: 8.9

Applications
For joining joints in iron and copper materials, stainless steels, nickel and nickel alloys in repair and fabrication.

Specially developed for joining CuFe2 tubes in the HVARC industry in conjunction with natural refrigerants such as CO2.

Further applications can be found in vehicle and electrical plant construction.

Processing instructions

Clean brazing surfaces and round off edges.

Suitable for flame and induction brazing.

The workshop and workplace should be adequately ventilated during brazing.

Flux

Use flux, e.g. Green Flux Activatec 1000 (paste-like). Use Albro flux for aluminium bronze.

Flux residues have a corrosive effect and must be removed from the brazed joint after brazing. Flux residues are water-soluble.
