一、合金的一般概况弹性合金是精密合金的一种,是精密机械和仪器仪表制造工业中极为重要的材料。弹性合金可分为高弹性和恒弹性两大类,这里仅概略介绍恒弹性合金。恒弹性合金的主要特点是在一定温度范围内(如:-60～+60℃,-20°～+100℃等),当温度发生变化时,它具有恒定的弹性。即是说它的固有振动频率不随温度而变化。当然,实际上没有绝对不变的合金,此类合金只是同其它合金相比,其弹性变化很小而已(相差几百倍)。一般用一个弹性温
First, the general profile of the alloy Flexible alloy is a precision alloy, precision machinery and instrumentation manufacturing industry is extremely important material. Elastic alloy can be divided into two categories of high elasticity and constant elasticity, only a brief introduction of constant elastic alloy. Constant elastic alloy is characterized by a certain temperature range (such as: -60 ~ +60 ℃, -20 ° ~ +100 ℃, etc.), when the temperature changes, it has a constant elasticity. In other words, its natural frequency does not change with temperature. Of course, there is virtually no absolute alloy, which is only a small change in elasticity (hundreds of times smaller) than other alloys. Generally use a flexible temperature
