ZM4合金是镁-稀土 锌-锆系合金。该合金的特点是在250℃下具有优良的抗蠕变性能,以及具有良好的气密性。 ZM4合金相当于英国的ZRE1合金和美国的EZ33A合金。ZM4合金比以前研制并生产的ZM3合金中的锌、锆含量略有提高,因而室
ZM4 alloy is magnesium - rare earth zinc - zirconium alloy. The alloy is characterized by excellent creep resistance at 250 ° C and good air tightness. ZM4 alloy equivalent to the United Kingdom ZRE1 alloy and the United States EZ33A alloy. ZM4 alloy than the previous development and production of ZM3 alloy in the zinc, zirconium content slightly increased, so room
