A copper alloy contains from 4 to 20 wt. % tin and various other metals. The alloys can be used in the manufacture of structural parts which are joined together through the use of heat such as jewelry, clothing accessories and mechanically stressed structural parts in a general machine-building or automotive industry. Iron, titanium, zirconium, hafnium, manganese, zinc, phosphorus and lead can also be present in the alloy composition.

Copper-tin alloys and uses thereof

A copper-tin-titanium alloy which consists of 12 to 20% by weight tin, 0.002 to 1% by weight titanium, remainder copper and usual impurities. It is possible to add further elements. Semifinished products made from the copper alloy according to the invention are preferably produced by thin-strip casting or spray compacting. Due to a particularly advantageous combination of high mechanical strength properties with excellent ductility, combined with good resistance to corrosion, semifinished products made from the copper alloy according to the invention have numerous possible uses.

A method provides for contactless measurement of the range between a transceiver unit for microwaves in the frequency band from 1 to 100 GHz and an object to be investigated using a pulse principle. The microwaves are focused onto the surface by an antenna to detect the contour of the object. In particular, the surface of a bolt produced using a spray compacting method can be detected.
