Extremely dense; tiny size, serious heft in hand.
What it is
Tungsten is one of the densest metals you will find in EDC. Pure tungsten is about 19.3 g/cm³, roughly two and a half times the density of Stainless Steel. EDC makers often use a tungsten alloy or tungsten carbide rather than pure tungsten, and the exact material depends on the maker. It commonly appears in weights, beads, inserts and spinner rings.
How it feels in your EDC
Even a small tungsten piece feels surprisingly heavy, giving a compact, concentrated weight in your hand. Makers often place it where mass matters most, such as the outer rim of a spinner or the core of a slider, to change balance and momentum. Results still depend on the full design, including bearings, weight distribution and fit.
Care & aging
Tungsten and tungsten carbide are very hard and resist everyday scratches well, so they tend to keep their look for a long time. That hardness also makes them brittle: a hard drop onto stone or tile can chip or crack them. Wipe it with a soft cloth, and avoid knocking it against other hard objects.
是什么
钨（Tungsten）是 EDC 中密度最高的金属之一。纯钨密度约 19.3 g/cm³，约为不锈钢的两倍半。EDC 品牌通常使用钨合金或碳化钨而非纯钨，具体材料取决于品牌。它常用于配重、珠子、嵌件和陀螺外环。
上手感受
即使是很小的钨件，拿在手里也重得出人意料，带来紧凑而集中的分量。品牌常把它放在最需要质量的位置，比如陀螺外缘或推牌核心，以改变平衡和惯性。实际效果仍取决于整体设计，包括轴承、重量分布和配合。
保养与老化
钨和碳化钨非常硬，能很好地抵抗日常划伤，外观可以长久保持。但高硬度也意味着脆：重摔在石头或瓷砖上可能崩口或开裂。用软布擦拭，避免与其他硬物磕碰。
