A copper alloy having the following composition (in % by weight): in each case 0.05 to 0.5% of at least three elements selected from the group consisting of Ag, Ni, Zn, Sn and Al, remainder Cu and unavoidable impurities, optionally 0.01 to 0.2% of one or more elements selected from the group consisting of Mg, Ti, Zr, B, P, As, Sb. Also, a current-carrying structural part made of a copper alloy and a cage rotor having multiple conductor bars and two short-circuiting rings, which are cast in one piece from a copper alloy.

Classification of the surface structure of heat exchanger tubes by means of doppler radar spectroscopy

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.
