Claims17
An alloy consisting of:
- about 60 to greater than about 50 atomic percent copper;
- about 15 to about 35 atomic percent manganese;
- about 1 to about 7 atomic percent nickel;
- about 7.5 to about 20 atomic percent zinc;
- about 1 to about 5 atomic percent aluminium;
- and
- incidental impurities
- wherein (3× atomic percent of aluminium)+atomic percent of zinc+(0.2× atomic percent of manganese) is between about 23.5% and about 32.5%;
- and wherein the alloy has ultimate strain of about 40-65%.
