Abstract:

Some properties such as mechanical properties, workability and corrosion resistance of wrought Zn-Cu-Ti type alloys containing 1∼6%Cu and approximately 0.1%Ti were mainly investigated, in respect of both effects of the Cu content and heat treatment. The results were as follows: (1) The alloys were strengthened with increase of the Cu content. (2) The heat resisting property in these alloys was based on the adequate Ti addition as in low-Cu alloys, and also their mechanical properties were most increased by low temperature annealing. (3) The alloys containing 2∼3%Cu gave the maximum tensile elongation. (4) The deep drawing property was improved with increase of the Cu content, and as for alloys containing an equal amount of Cu, the property was more desirable in the as-rolled condition than the annealed. (5) The bending property and corrosion resistance became worse with increase of the Cu content, but the effect on the latter was insignificant. (6) The Zn-Cu-Ti type alloy containing 2∼3%Cu was considered most promising in practical use.
