Thin Dense Chromium

What is Thin Dense Chrome?

Thin Dense Chrome (TDC), commonly referred to as flash chrome or functional chrome, is an electroplated chromium coating applied typically for manufacturing applications within a general thickness range of 0.00005” to 0.001” (1.27 to 25.4 µm). There are two distinct thin dense chrome surface textures - micro nodular and micro cracked - each creating different TDC products.

All thin dense chrome products share similar metallic properties, features, and benefits. In addition to the two primary surface texture options, TDC can also be combined with nickel-based layers and nanodiamond technology in hybrid coatings. Understanding the application conditions, variables, and base metal properties can aid in determining the ideal TDC product for maximizing performance.
