Zinc Coated Brake Rotors

Brake rotors are regularly exposed to water salt and other corrosive elements.

Zinc coated brake rotors.

Each performance brake rotor is immersed in different solution tanks during the coating process. The coating that remains will continue to protect the hub vanes on vented discs and rotor edges. The cross drilled brake rotors are sold in pairs and come zinc coated in either black or silver to help prevent rusting and give you a performance race look. An example of course is in the automotive industry.

One way was to apply a coating to prevent rust. Rotor corrosion comparison test result is finally here. Wherever the brake pad sweeps the rotor area the coating will be removed by the normal operation of the disc brake system. The final result is a thick protective coating that will help prevent rusting and give you a great custom look.

Wagner s budget brake rotors are coated for corrosion and rust. Numerous industries now actually make use of zinc electroplating in order to further enhance the potential of their products. As brake rotors are made of iron they naturally rust and when exposed to minerals such as salt the rusting oxidization tends to speed up. The zinc coating will serve as a protective barrier before rust reaches the metal it will have to deal with its zinc protection first.

This leaves you with a very ugly looking rotor. That s why the coating on acdelco silver advantage coated brake rotors contains zinc and aluminum which naturally attract corrosive reactions more than iron helping to protect the rotor underneath. Thermic black coated discs are being phased in. These rotors are made from aluminum and have a zinc coating to protect against rust and extend their operating window.

These rotors are guaranteed to fit original equipment manufacturer specs without modification and are machined balanced with a double disk smooth surface ground finish to reduce noise. After over 3 months of driving the vehicle outside doing a spray test with 5 nacl solution or 5 s. Premium brake rotors in the uk or europe. For a more in depth look at coated brake rotors check out the video below.

However due to certain castings the zinc coating may not adhere to small areas of some rotors.
