Weightier than Ti for a satisfying spin; can go jet black.
What it is
Zirconium is a corrosion-resistant metal with a natural silver-gray color. At roughly 6.5 g/cm³, it is denser than Titanium but less dense than Stainless Steel. EDC makers use it for bodies, buttons and decorative accents, often choosing a heat-treated black surface for contrast. The exact alloy and treatment depend on the maker.
How it feels in your EDC
For a piece of the same shape and volume, Zirconium adds noticeable weight compared with Titanium. That can make a slider feel more substantial or give a coin a satisfying presence in your palm. It does not guarantee longer spins or a particular sound: bearing quality, weight distribution, magnets and construction matter too. Sandblasted, polished and textured surfaces also change the feel, so judge the complete design rather than the material alone.
Care & aging
Controlled heating can create a dark oxide surface on Zirconium. This is a surface treatment, not the metal's color throughout, so deep scratches may reveal lighter metal beneath. Wear varies with the treatment and how you carry it. Start with a soft cloth and follow the maker's care instructions. Avoid abrasive polishing on a blackened finish unless you intentionally want to alter its appearance. Keep cleaning liquids away from bearings, magnets and internal mechanisms.
是什么
锆（Zirconium）是一种耐腐蚀金属，天然呈银灰色。密度约 6.5 g/cm³，高于钛、低于不锈钢。EDC 品牌用它制作主体、按键和装饰件，常选用热处理形成的黑色表面来做对比。具体合金和处理方式取决于品牌。
上手感受
同样形状和体积的作品，锆比钛明显更有分量，能让推牌更厚实，或让硬币握在掌心更有存在感。但它不保证更长的旋转时间或特定声音：轴承质量、重量分布、磁铁和结构同样重要。喷砂、抛光和纹理表面也会改变手感，所以要看整体设计，而不只看材质。
保养与老化
控温加热可以在锆表面形成深色氧化层。这只是表面处理，并非整块金属都是这个颜色，深划痕可能露出底下较浅的金属。磨损程度因处理工艺和携带方式而异。先用软布清洁，并遵循品牌的保养说明。除非有意改变外观，否则不要对黑化表面做研磨抛光。清洁液要远离轴承、磁铁和内部机构。
