ABSTRACT:
Alloys comprising by weight 70-82% Copper, 6-10% Aluminum, 0.1-24% Zinc and 0.1-12% Manganese are particularly suited for use as the material of heat recoverable articles as they exhibit good ductility and stability and are easily worked by hot working techniques. Additionally, they have M.sub.s temperatures which enables them to be fabricated into heat recoverable articles useful in many applications.
A heat recoverable article, made from a quarternary alloy of copper, aluminum, manganese and zinc whose composition falls on or near the eutectoid line, is particularly suited for use in circumstances where the article has been recovered from its recoverable state under conditions such that a degree of unresolved recovery remains.
