More mobile apps for design engineers are springing up all over, including general-purpose utilities like calculators, as well as more specialized tools. The latest is a Wesgo Metals braze alloy app from Morgan Technical Ceramics that has been designed for the iPhone, iPod touch, and iPad. It is available free of charge.

The Wesgo Metals app helps engineers find the right braze alloy for their applications by including the forms in which a given alloy is available, along with that alloy's mechanical properties. The app features several different sorting functions, including by product name, by the elements within the alloy, or by the braze liquidus temperatures.

The app also lets users find the right braze alloy based on inputting information about the two substrates to be joined. In addition, a calculator lets users compute the linear coefficient of thermal expansion of different brazed assembly materials to show how much a part will expand at a particular braze temperature, giving the engineer the ability to identify the optimal component fit.

The app's functions are available in both metric and Imperial units of measurement. Data on more than 60 different alloys is included, as well as their mechanical properties datasheets. More than 60 different substrate coefficient of thermal expansion values are included.

Wesgo Metals manufactures and supplies high-purity, low-vapor pressure brazing alloys in a variety of forms. For both precious and non-precious alloys, these forms include atomized powder, discs, evaporation slugs, extrudable paste, Flexibraze, preforms, ribbons, rings, sheets, washers, and wire. Precious alloy fillers include gold, silver, platinum, and palladium-based materials. Several different non-precious alloy fillers for brazing applications between 500 degrees C and 1200 degrees C are available, including copper and copper alloys, nickel and nickel alloys, nickel-iron and nickel-iron-cobalt, and others.
