What is ISO 5179 about?
ISO 5179 specifies three test methods for investigating brazeability. A spreading test shows testing method with measurement of the spread area of the filler metals.
A T-joint test describes a scheme to construct a T-shape design by the test pieces and a testing method. A varying gap test describes a test piece and a testing method for assessing the influence of the various parameters which can influence brazing during manufacture as a function of clearances.
Who is ISO 5179 for?
ISO 5179 on Filler metals for Brazing applicable to:
- Precious metal jewellery Industry
- Manufacturers of aircraft & aerospace
- Dental applications
- Pipe fittings manufacturing
- Electrical components manufacturers
Why should you use ISO 5179?
Brazing is considered to be one of the most effective methods of joining two metals together. It is important to know not only the way in which the filler metal wets the surface of the parent metal but also this same liquid filler metal behaves in a given gap. . ISO 5179 provides tests methods for determining brazeability, which helps improve the efficiency and quality of brazing operations.
Apart from the physical properties of the brazing alloy and the mechanical properties that can be expected from the joint, there are several factors to consider while designing and fabricating a brazed joint It's important to understand brazeability in relation to the operating conditions adopted, ISO 5179 provides guidelines in this regard.
What’s changed since the last update?
BS ISO 5179:2021 is the second edition cancels and replaces the first edition ISO 5179:1983, which has been technically revised.
The main changes compared to the previous edition are as follows:
- The spreading test has been added
- The T-joint test has been added
