Tin is important as it imparts an improved "fluidity" to the moltenalloy and helps in mold filling.
加锡是很重要的，因为它可以改进熔融合金的流动性，从而使其易于注入模具。
2
Some preparation technology, such as the method of water quenching the moltenalloy and explosive welding, are briefly introduced.
同时简单介绍了熔体水淬法、 爆炸焊接法等制备技术。
3
The completed assembly is coated with a ceramic slurry, allowed to dry and then heated to melt out the wax leaving a ceramic mould into which the moltenalloy is poured.
