ExtremEtch Chemical Finishing
Alexandria Industries is excited to introduce the ExtremEtch process to the aluminum extrusion marketplace, while providing greater, unique advantages to its customers’ product lines.
This specialized technology and process, patented in 2007, has been further developed by Alexandria Industries and continues to advance through process studies and strategic process investments. ExtremEtch is significantly different and a very cost effective aluminum etching process compared to other chemical etching processes currently used throughout the industry.
Whether your product is currently MIL SPEC Type III Hard Coat Anodized or clear, black sulfuric anodized, this process is compliant to both environments. ExtremEtch will produce significant results, while eliminating costly secondary mechanical finishing operations. Another valuable benefit is minimal reflectivity levels and reduced cosmetic defects.
ExtremEtch defined: A chemical finishing process applied to aluminum products, which produces an excellent uniform, deep matte finish and is highly effective in hiding machining marks and mild scratches or abrasions as a result of manufacturing precision components.
9 Advantages of ExtremEtch
- Uniform finish
- Deep matte finish
- Minimal reflectivity levels
- Very low gloss readings levels
- Hides marks, scratches and abrasions
- Tolerance control with process repeatability
- Significant reduction of material removal (Threaded holes, Critical I.D. and O.D. dimensions)
- Eliminates costly secondary mechanical finishing operations such as media blasting (i.e. - Sand blast, Bead blast, Ceramic blast, Glass blast etc.)
- Eliminates Ghosting, a direct result of process variance and residues of media blasting
