MAGNESIUM ALLOY FILAMENT, AND BOLT, NUT, AND WASHER

摘要

A filament configured from a magnesium alloy comprising, in mass percent, 0.1-6% Zn and 0.4-4% Ca, with the remainder being Mg and inevitable impurities, wherein, when a creep test is performed on the filament under conditions of 150°C temperature, 75MPa stress, and 100 hours holding time, the filament has a creep strain of 1.0% or less. It is possible to improve heat resistance through interaction of Zn and Ca, and to make the creep properties of the filament excellent. It is also possible to make the plastic workability of the filament excellent by including therein Zn and Ca in a specific range.
