Abstract (en)
[origin: EP0926251A1] A titanium-containing tin-bronze, of specific composition, is new. new copper-tin-titanium alloy has the composition (by wt.) 12-20% Sn, 0.002-1% Ti, balance Cu and impurities. ADDITIONALLY CLAIMED ARE: (i) a casting produced from the above alloy and exhibiting a segregated coarse phase content of less than 10 vol. , an undetectable content of segregated particles of greater than 50 microns cross-sectional size, a cold deformability of ≥ 20% (w.r.t. cross-sectional change) and up to 10 vol. micro-segregation with a typical linear distribution of less than 20 microns width; and (ii) production of strip, wire, profile or tubular semifinished products of the above alloy by thin strip casting or spray compacting, followed by hot and/or cold working optionally with intermediate anneals.
