Liquid metal (technically, metal which is liquid at room temperature) is mysterious to many people. It challenges the metal stereotypes we have -most metals are too hot to touch when they are liquid – and most metals are solid at room temperature. Here are six things you need to know if you are planning on using liquid metal:
1) 可用合金
有 5 种标准（不含汞）液体合金：
- 46L号印度合金：（7-8°C）61.0%镓/25.0%铟/13.0%硒/1.0%锌
- 51E 号印度合金：（11°C）66.5%镓/20.5%铟/13.0%硒
- 51 号印度合金：（11-17°C）62.5%镓/21.5%铟/16.0%硒
- 60号印度合金：（16°C）75.5%镓/24.5%铟
- 77 号印度合金：（16-25°C）95.0%镓/5.0%铟
The melting points listed above are solidus-liquidus. Indalloy #51E and #60 are both eutectic alloys.
2) 技术数据

3) 成本
The prices of indium and gallium are dictated by supply and demand (as you would expect). Right now – at this writing – the price of indium is quite low. A year from now the price could be higher or lower, the only clear bet is that it will fluctuate. If you are sitting on an old quotation, be sure to have the quote updated. You might be pleasantly surprised!
4) 运输
液体合金用聚乙烯瓶装运。如果你生活在寒冷的气候中，你可能会收到固体金属。不要惊慌，当它达到室温时就会融化（相信你的物理学，我的朋友们）。不需要采取任何特殊的 "解冻 "措施--最好保持原包装，让金属在室温下融化。如果您觉得有必要加热包装，温度不要超过 65°C。
5) 支持
When you buy liquid metal from the Indium Corporation, you are also getting application support. Let us know if you have any questions before, during, or after application: [email protected]
6) 报废（回收/再利用）
Most liquid metals can be used and reused many times. Of course, this is application dependent. If impurities arise from excessive use, or if you just don’t need the liquid alloy any longer, we have a recycling program. Recycling does have a minimum quantity threshold where it becomes feasible. This depends on many factors, including the price of indium and gallium (as mentioned above). The best way verify that reclaiming your material is practical is to contact our reclaim team: [email protected].
If you have a new or current application for liquid metals, I would be very interested in hearing from you. Share your thoughts with me at [email protected]
