Titanium Jigs For Coating

Titanium jigs for plating Any project to anodize requires a reliable hanger/jig/rack, first to prevent it from falling to the bottom of the anodizing tank, and second to allow the current to be safely transferred from the jig to the workpiece. Anodic oxidation clamps are usually made of aluminum or titanium. Aluminum fixtures must of course be anodized and must be chemically stripped. Continuous anodizing and stripping can result in short service life, so there is no need to strip titanium after the anodizing process. Item Name: titanium jig for coating Size:Customized size is welcomed Material: Titanium Gr1, Gr2 Application,Electroplating industry Surface:Sand Blasting, Acid Washing Parameter:Current density≤2000A/M2 Temperature:<65°C PH: 0.1~14 Max content of Fluoride ion is 200PPM Chemical composition (Wt%) ASTM No. Fe max O max N max C max H max Pd Al Bal Grade 1 0.2 0.18 0.03 0.1 0.015 - - Ti Grade 2 0.3 0.25 0.03 0.1 0.015 - - Ti Physical Properties (Min) ASTM Grade Alloy Composition Tensile Strength Yield Strength Elongation min % ksi Mpa ksi Mpa Grade 1 Unalloyed Ti ("Pure") 35A -CP1 35 240 25 170 30 Grade 2 Unalloyed Ti ("Pure") 50A -CP2 58 400 40 275 25
