日本1986年硬质合金总产量为2375t,同历史最高记录1985年相比,产量降低3％,产值为1463亿日元,降低6％。其主要原因是国内机械工业的需要减少和出口不景气,特别是金属切削机械的生产及出口比1985年降低12％。1987年也不能期待汽车、一般机械、精密机械、金属制品等部门的需要量恢复,预测比1986年降低20％。土木机械将同1986年持平。硬质合金用的原料1986年消费降低,1987年也不会恢复。
In 1986, the total output of cemented carbide in Japan was 2375t, a decrease of 3% from the record high of 1985 and a value of 146.3 billion yen, a decrease of 6%. The main reason for this is the decrease in domestic demand in the machinery industry and the downturn in exports. In particular, the production and export of metal-cutting machinery have dropped by 12% over 1985. In 1987, the demand for automobiles, general machinery, precision machinery and metal products could not be recovered. The forecast is 20% lower than in 1986. Civil machinery will be the same as in 1986. Consumption of raw materials for cemented carbide decreased in 1986 and will not recover in 1987.
