The resistance to pressure was tested in 320 Amalgam samples of alloy-mercury in relations of 4:3, 5:5, 5:6 and 5:7 under packing pressures of 2, 5, 10 and 15 N/mm2. These tests were made with a commonly-used and a copper-rich alloy. Very dry mixtures, which condense under low packing pressures, show low pressure resistance.
在2、5、10和15 N/mm²的充填压力下，对320个合金与汞比例为4:3、5:5、5:6和5:7的汞合金样品进行了抗压强度测试。这些测试使用了一种常用合金和一种富铜合金。非常干燥的混合物在低充填压力下会凝聚，其抗压强度较低。
