Sumitomo Metals Industries have announced a new corrosion-resistant grade of steel with added tin that can be used to make bridges that require far less painting or even no paint at all. Published test results show that tin addition dramatically reduce the corrosion of steel in a salt-spray test, with no detriment to strength, weldability and other parameters. Lengthening...

A new joint venture Itrimex is developing a new way to recover tin in solder, as well as other metals, from the vast amounts of e-waste discarded every year. Until now conventional technology for recovering metals from waste electronics has been based on crushing everything and burning it at high temperature to melt and separate the metals from slags, with the main focus being recovery of copper and precious metals. The new proprietary technology takes a different approach to give a fast and low energy solution to metals recovery with...

As electronics become used in more and more challenging environments the solders that glue them together need to become stronger.  Researchers across the world are using microscopic particles to make a new generation of super strong solders. Adding tiny particles of silica, carbon or other metals has been found to dramatically increase the strength of solders, sometimes...
