Johnson Matthey Orobraze™ 950 Gold Bearing Brazing Filler Metal
Categories: Metal; Nonferrous Metal; Precious Metal; Gold Alloy; Solder/Braze Alloy

Material Notes: Orobraze™ 950 is a high purity gold bearing brazing filler metal. It is extensively used in aerospace components and thermionic valve / vacuum tube devices as well as in other specialized applications.

Orobraze™ 950 exhibits excellent high temperature strength up to 500°C and oxidation resistance up to 800°C. Because of the alloy’s elevated temperature properties it is used extensively in the manufacture of components required to operate at high temperature, for example turbojet aero-engine components. The alloy produces small exceptionally smooth fillets at the joint edges that do not disturb the aerodynamic gas flow in aero-engine components.

Orobraze™ 950 is suitable for vacuum furnace brazing, as it contains no volatile elements. Grade 1 Orobraze™ 950 has impurity levels which make it suitable for brazing components that operate at elevated temperatures in ultra high vacuum, such as vacuum tube devices. It is also suitable for step brazing in complex assemblies.

Orobraze™ 950 also offers good corrosion resistance in many chemical environments and its joints are resistant to interfacial crevice corrosion on stainless steels in aqueous service environments. These properties have been put to use in the paper making industries for example. Typical joint gaps are in the range of 0.025-0.1mm depending on parent metals, joint configuration and brazing methods.

Typical applications are for brazing stainless steel, high temperature nickel alloys and super alloys. It can be used for joining copper to these alloys in thermionic valve devices.
