Precious Metal Brazing Alloys

Meta-Braze™ Gold Based Brazing Alloys

High purity gold containing brazing alloys find use in a variety of applications including electronic components, imaging equipment, aerospace, oil and gas and chemical. The alloys in this range are normally selected because of their ability to withstand chemical attack and retain strength at elevated temperature or because they can be produced in ultra pure V1 grade sometimes called ‘vacuum tube grade’.

Meta-Braze™ Palladium Bearing Brazing Alloys

High purity palladium containing brazing alloys find use in a variety of applications including electronic components for imaging, aerospace, oil and gas and chemical. The alloys in this range are often selected because they can be produced in ultra pure V1 grade, sometimes called ‘vacuum tube grade’, making them suitable for brazing metallised ceramics in electronic components. Palladium bearing alloys also exhibit good corrosion resistance and strength at elevated temperatures.

Meta-Braze™ High Purity Silver Brazing Alloys

High purity silver containing brazing alloys find use in a variety of applications predominantly in electronic components. A major use is for joining metallised ceramics used in vacuum tube devices. The addition of nickel to Meta-Braze™ Ag 071 improves wetting on stainless steel components, whilst the indium containing Meta-Braze™ Ag 063 and Meta-Braze™ Ag 061 provide the possibility for a step brazing operation when used with Meta-Braze™ Ag 272.
