Abstract

1381816 Watch cases DAINI SEIKOSHA KK 30 March 1972 [3 April 1971] 15042/72 Heading G3T [Also in Division C7] Watch cases having a wear-resistant golden colouration arc formed from sintered tantalum carbide alloys containing at least one of iron, cobalt or nickel to a total of 30%, and optionally up to 5% of one or more of molybdenum titanium, chromium, vanadium, niobium, tantalum, tungsten and zirconium. The materials should be sintered to a density of at least 88À7% of the theoretical density.
