Nickel-brazing is unique in the brazing world in that each of the nickel-based brazing filler metals (BFMs) available for use today depends on the use of temperature-lowering ingredients (i.e., temperature-depressants) such as boron, phosphorus and/or silicon to enable the BFM’s usefulness for joining stainless steels and many other superalloys for critical aerospace applications.
We are past the halfway mark of the year, which in political speak means we have four months until the midterm election and only five months in the remainder of this Congress – possibly the last fully controlled by Democrats during President Biden’s first term in office.
After excavating ancient coin molds (dated to the 11th century) in Mali in 2005, an archaeologist wanted to find out how medieval Africans purified the gold they were using for their currency. Sam Nixon discovered little droplets of highly refined gold left over in the molds and fragments of glass.
Engineer Zsolt Pataki wanted to create the ultimate fountain pen using innovative production methods with advanced materials. The result is a fountain pen made from a solid titanium bar for the ultimate weight, look and feel, hardened by ExpaniteHard-Ti to make it long-lasting and virtually unscratchable.
Which companies produced the most steel in 2021? If you want the answer to that question, here’s a comprehensive list courtesy of the World Steel Association.

BMW of North America LLC issued a safety recall for all 2019 and 2020 K 1600 GT, K 1600 GTL, and K 1600 B motorcycles – around 1,625 total units – because of a manufacturing defect with the link strut on the rear suspension.
Did you know that nearly all countryside houses in Sweden are painted red? Incidentally, this tradition made its way to America in the form of the big red barn. The color, known specifically as Falu red, comes from the Falun copper mine in central Sweden, which dates back to the 9th century. At one point in time it was the largest copper mine in Europe.
Workers recently used recycled wind-turbine blades to install a pedestrian bridge on a former train-track bed in County Cork, Ireland. This makes it the second “blade bridge” in the world. Engineers installed one in western Poland in October 2021.
In refractory lining maintenance, recommendations for repairs and relines often consist of selecting a similar or equivalent material to replace the original. Sometimes that’s sufficient.
Industrial furnaces are widely used to melt metals for casting or heat materials for change of shape (forging) or change of properties (heat treatment).
