Abstract
PURPOSE: To provide a white hard amorphous material with superior lustr for watch exterior parts by alloying Pd with Si in a specified ratio.
CONSTITUTION: A molten alloy consisting of Pd 70W90 atomic% and Si 10W30 atomic% is quenched at a cooling rate of about 103°C/sec to manufacture an amorphous plate material or wire rod. This material has superior corrosion resistance, high hardness and high scratch resistance as well as luster and color which cannot be given by crystalline metal. Accordingly, it is suitable for use as a material for the case, band, crown, button, face, parting plate and hands of a wristwatch, and the cases, etc. of a pocket watch and a ring watch.
