Standard Chrome. Standard chroming is where we grind the metal to the base then polish up in grits to about 400 then do 2 nickel plating and one chrome. There are more polishing lines in standard chrome plating than in our show chrome finish since show chrome involves copper plating and higher grit sanding. We can plate most metals but cannot ...

When comparing to standard hard chrome plating, TM105 is brighter, harder and more corrosion resistant . Also, deposits can be plated up to 71 Rockwell C compared to standard chrome, which ranges from 64 to 67 Rockwell C. It's brightness and low coefficient of friction make it ideal for molds and metal cutting tools for example.
