Why chemically blacken metal? It is not a lacquer or plating, but a thin black layer that, together with a post-treatment (usually oil or sealer), gives practical advantages: protection against rust, sleek appearance and smoothly working parts \u2014 without noticeable size change.  \n\nView the <a href=\"https:\/\/verzinkshop.nl\/categorie\/chemisch-zwarten\/\">category metal blacks<\/a> on the webshop here.\n<h3>When do you choose black oxide?<\/h3>\n<ul>\n \t<li>Bolts, nuts, axles, dowel pins, guides<\/li>\n \t<li>Tools &amp; measuring instruments<\/li>\n \t<li>Machine and equipment construction, automotive and assembly work<\/li>\n \t<li>Aesthetic parts where thin, black and dimensionally stable are desired<\/li>\n<\/ul>\n<h2>Corrosion protection<\/h2>\nThe black layer in combination with oil\/sealer protects metal parts from rust. Ideal for parts that are assembled or in stock. \n\nVerzinkshop offers two sealers: Verzinkshop <a href=\"\/deepseal-metaal-sealer\/\">DeepSeal<\/a> (oil-based) for durable protection indoors and outdoors, and Verzinkshop <a href=\"\/acryl-metaal-sealer\/\">Acryl Sealer<\/a> \u2013 a very thin, water-based lacquer without structure for a transparent finish very suitable for indoor projects.\n<h2>Durable layer<\/h2>\nCold black oxidation is a conversion layer in the metal itself, so it does not chip or peel.\nDoes something get damaged? Touch-ups are simple: remove the sealer with a solvent and blacken again and you&#8217;re done. You don&#8217;t have to sand and you don&#8217;t see a transition between the old and new layer.  \n<h2>Smooth movement and assembly with an oil sealer<\/h2>\nAfter blackening, there is usually a post-treatment with an oil-based sealer. This provides extra protection and ensures that parts rotate\/slide more smoothly (guides, shafts, threads). \nMetal on metal can eat into each other and damage each other during initial assembly or use. The black layer of oil acts as a thin lubricating film that sacrifices itself a bit with the first movement, so that the parts do not get stuck and work neatly together. \n<h2>Dimensionally stable (practically no layer thickness)<\/h2>\nBlack oxidation hardly changes the size: about 0.10\u20130.25 \u03bcm (0.00010\u20130.00025 mm). Polished surfaces remain shiny and heat-treated parts retain their hardness. So you can simply finish critically fitting parts.  \n<h2>Aesthetics &amp; less glare<\/h2>\nThe deep black color looks professional and provides a nice contrast with markings. The matte finish reduces glare, which is pleasant with tools and appliances. \n<h2>Fast and cost-efficient<\/h2>\nThe process is fast and often cheaper than painting or galvanizing. Little to no drying time, parts can quickly proceed to assembly. \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Why blacks (black oxidize)?<br \/>\nBlack oxidation is a chemical conversion treatment for steel\/iron (and for stainless steel with another liquid).
