ABSTRACT:
A tape cartridge comprising a flat base plate and component parts mounted on the plate, including pins that are nominally perpendicular to the base plate and which support and facilitate tape transfer within the cartridge; the plate comprising an aluminum alloy having a yield stress in the range from about 25,000 to 30,000 psi. The base plate preferably comprises from about 0.5 to 3 parts by weight Si and from about 0.1 to 0.7 parts by weight Fe, based on 100 parts of the aluminum alloy. The base plate of the present invention may optionally comprise one or more of the following: up to about 1 part by weight Mn; up to about 2 parts by weight Mg; and mixtures thereof; based on 100 parts of the aluminum alloy.
