广东低熔点合金厂家批发伍德合金

伍德合金：
 
外观：灰白色有光泽的金属。
成分：含铋38～50％、铅25～31％、锡12.5～15％、镉12.5～16％。熔点低70℃。
性质：以金属铋为基的一类低熔点合金。如加铟和汞，熔点进一步降低。伍德合金的强度不高，室温下仅为30MPa，延伸率3％，硬度很低，为25HBS。熔融法制备，压力加工成材。伍德合金用途： 伍德合金用于自动洒水系统的塞栓，弯金属管时的填充物，金相试样的嵌镶剂，铸造模型以及用作Ag、Co、Ni、Sn、Zn电解分析时的阴极涂层。可用于电子电气自动控制，作热敏元件、保险材料、火灾报警装置等。

Elbow filler alloy Features:
1, the melting point is very low;
2, a lower coefficient of thermal expansion;
3, good mold release;
4, can be recycled.
The fusible alloy is a special polyhydric eutectic metal after solidification can be immediately put into production use, with the same temperature of hot water or oil soaked Note fusible alloy workpiece easily from the mold on the low temperature alloy, a fixture or parts, metal pipe recovered can be reused, and the very low thermal expansion coefficient. Simple to use, and low cost.
The other can be customized according to customers' different production needs all kinds of the melting point of the alloy.
Melting point there is: (48 ° C, 58 ° C, 70 ° C, 80 ° C, 91 ° C, 124 ° C, 130 ° C, 138 ° C, 145 ° C, 170 ° C, 182 ° C)
