白金珠宝以其光泽亮丽和经久耐用而闻名于世。但有一个问题经常出现:白金有磁性吗?
The simple answer is no—for the most part, white gold is 无磁性. However, there are a few nuances around white gold’s composition that explain why some pieces may exhibit minor magnetic properties.
在这本完整的指南中,作为专业人士 钕磁铁制造商, we’ll uncover everything you need to know about white gold and magnetism. By the end, you’ll be able to confidently assess whether your glimmering jewelry is attracted to magnets.

揭开白金合金的神秘面纱
要了解白金是否具有磁性,首先要了解白金到底是什么。
白金 是一种合金,而非纯金属。它将黄金与镍、银、钯或锌等白色金属结合在一起,形成一种耐用的银色金属,是制作珠宝的理想材料。
合金中使用的特定成分和比例会影响其颜色、耐用性、成本以及磁性。
例如,镍和银使白金呈现白色。同时,锌使合金更加坚硬,而钯则赋予了白金亮丽的光泽。金仍然占合金的大部分,通常在 58-75% 之间。
因此,在 18K 白金合金中,18 部分是黄金,6 部分是银、锌、镍或其他白色金属。
这种合金混合物能让珠宝商将白金加工成令人惊叹的设计,从白金订婚戒指到迷人的手镯,不一而足。
And while pure gold on its own is not magnetic, the other metals introduced into white gold can change things…
白金有磁性吗?
No – in almost all cases, 白金无磁性.虽然其合金中确实含有一些镍,但数量通常太少,无法产生任何明显的磁性。不过,镍或铁含量较高的廉价服装珠宝可能会显示出微弱的磁性。如有疑问,请让专业人士对白金首饰进行鉴定,以确认金属纯度。信誉良好的零售商会保证无磁性的高品质白金。
哪些金属使白金具有磁性?
正如我们刚刚介绍过的、 白金合金 将黄金与各种白色金属混合,创造出标志性的银色光泽。
但是,在镍、锌、银和其他成分中,哪些能真正激发潜在的磁性呢?
罪魁祸首是 五分美金.在白金中加入这种多用途金属,不仅可以使其呈现白色,还可以增加硬度。
纯镍和镍合金也是常见的磁性金属。因此,逻辑上可以得出 镍含量高的白金可能具有轻微磁性.
Besides nickel, iron and cobalt are also ferromagnetic metals with innate magnetism. However, these aren’t typically ingredients in white gold alloys, although impurities are possible.
因此,镍是使白金具有磁性的主要成分。许多质量较差的白金合金也含有大量的镍,这也是它们可能粘附磁铁的另一个原因。
That said, it’s unlikely you’ll be able to lift a white gold watch or bracelet off the table with a standard refrigerator magnet. But minor attraction is possible with pieces containing nickel.
白金珠宝消磁解决方案
If you just grabbed a refrigerator magnet and your cherished white gold ring flew onto it, don’t fret! A few simple tips can help demagnetize pieces.
首先,请您的珠宝商评估白金含量。了解确切的合金细分,就能洞察磁性风险。
从这里开始,你有几个选择:
- 镀铑 – Adding an imperceptible layer of shiny rhodium effectively blocks nickel from interacting with magnets. It also enhances shine!
- 珠宝清洁 – Over time, commercial solutions, lotions and metals from other jewelry can accumulate on white gold, altering surface reactivity. Careful cleaning resets your pieces.
您还可以通过购买含镍较少的白金来降低未来的磁性风险。可选择不含镍的金合金或以钯为主的金合金。
虽然给现有珠宝消磁需要花费一些精力,但在购买新珠宝时避免使用磁性金属则要简单得多。
收获:白金有磁性吗?
So there you have it—the complete truth about white gold and magnetism!
虽然纯金本身没有磁性、 白金合金 掺入镍元素以获得颜色和硬度的材料会表现出轻微的磁吸引力。
Yet it’s unlikely your average fridge magnet alone can hoist that white gold bracelet off the table. Substantial nickel levels are required for this, more so than the 8-20% nickel typical in white gold alloys.
Still, it’s good practice to 磁性测试, especially if buying secondhand gold jewelry. Other red flags something isn’t genuine white gold include flaking, yellowing and lack of stamps inside bands or clasps.
但是,如果您精美的白金首饰确实被磁铁吸住了,也不必惊慌!镀铑和清洁等快速消磁解决方案可以重置任何活性金属。或者,您也可以选择使用钯等替代增白剂的优质金合金。
And whatever you do, don’t let magnets stop you from rocking gorgeous 白金首饰 无论您走到哪里!那些闪闪发光的白金钻石戒指和项链理应熠熠生辉,让世人瞻仰。
