Gold Braze 3034™

Gold Braze 3034™ Technical Data


Gold Braze 3034 can be used on any of the common ferrous and non-ferrous alloys. This alloy exhibits good wetting characteristics on metallized ceramics. Typical applications include brazing of electron tubes, vacuum tubes, wave guides and electronic industry.

Brazing Characteristics

Gold Braze 3034 is generally used in reducing, vacuum, or inert atmosphere. The composition of the alloy allows for use in applications where braze filler metals low in volatile constituents are required. Due to its narrow plastic range, Gold Braze 3034 exhibits free flowing characteristics.

Properties of Brazed Joints

The properties of a brazed joint are dependent upon numerous factors including base metal properties, joint design and brazing technique. For controlled atmosphere brazing or vacuum brazing the recommended radial joint clearance for gold base alloys fall within 0.000in – 0.002in (0.00mm-0.05mm)range.


Gold Braze 3034 alloy conforms to: Unified Numbering System (UNS) P00300, American Welding Society (AWS) A5.8/A5.8M BAu-5 and Society of Automotive Engineers (SAE)/AMS 4785
