Screws plated nickel or galvanized which is more corrosion resistant

Screws plated nickel or galvanized which is more corrosion resistant

From the point of view of corrosion resistance, screw nickel plating is more resistant to corrosion than galvanized.

  1. Characteristics of galvanized screws and nickel-plated screws

Galvanizing refers to covering the screw surface with a zinc layer, which is usually used to prevent corrosion of steel parts. Its advantage is that the cost is low, but its corrosion resistance is limited, it is easy to be affected by chemical reactions, and the zinc layer gradually wears down with the passage of time and weathering. Galvanized screws are suitable for use in dry environments, and not suitable for use in wet or acidic environments.

Nickel-plated screws are screws that are covered with a nickel layer on the surface of the screws. In contrast, the advantage of nickel-plated screws is that they are stronger and more resistant to corrosion than galvanized screws, because the nickel layer is chemically more stable and not easily oxidized or corroded by chemical reactions, which can be used for a long time. In addition, the nickel layer also has good wear resistance and aesthetics, which is suitable for the manufacture of high value-added products.

2, which screws are more corrosion resistant?

From the point of view of corrosion resistance, nickel-plated screws are more resistant to corrosion than galvanized screws. Although galvanized screws perform well in a dry environment, when they are exposed to humidity, high humidity, or an environment containing strong acids and alkaline substances, they are easy to oxidize and be affected by chemical reactions. On the contrary, the surface of nickel-plated screws is smoother and more decorative, and it can be used in a wider range of conditions, more durable and suitable for a variety of different types of products.

3, how to choose the right screw material?

Choosing the right screw material depends on the actual use environment. If you need a screw material to resist the effects of moisture, strong acids or alkaline substances, then nickel-plated screws are a better choice. If you need a screw material for a dry environment only, and cost is a factor you need to take into account, then galvanized screws are the best choice.
