    M6*11 steel Welding Nut with Environmental Black Zinc.


    Description

    Welding nut is the material (same or different) of the workpiece to be welded. It is by heating or pressurizing or both, and with or without filling material, the material of the workpiece can reach the atomic construction and form a permanent connection.


    Welding nuts are fasteners that have internal threads and are used in conjunction with bolts. A mechanical part that has internal threads and is used in conjunction with a screw to transmit motion or power.dy.


    The difference between environmentally friendly black zinc and general black zinc:

    1. Product appearance. Normally, trivalent chromium passivation is not as bright as hexavalent chromium and has a good appearance. However, the current level of trivalent chromium is developing rapidly, and the appearance is basically It can meet the requirements of very dark, but generally trivalent chromium can be very dark, the salt spray test will not be too good.

    2. In terms of formula, the current formula of hexavalent chromium is still mainly silver nitrate, which is easy to see.

    3. In the salt spray test, when it is very dark, hexavalent chromium is still better at present.

    4. In terms of cost, the two are actually the same. The unit price of hexavalent chromium is high, but the amount used is small. The opposite is true for trivalent chromium.

    5. The best way to distinguish is to analyze the main metal components of the passivation solution or passivation film. The main components of trivalent chromium are trivalent chromium and cobalt, and the main metal components of hexavalent chromium are hexavalent chromium and silver.
