The difference between galvanized materials and galvanized aluminum

1. The difference in coating composition

1. The coating of galvanized materials is mainly composed of zinc. The zinc coating forms a protective layer on the metal surface, which can slowly release zinc elements, thereby playing the role of anti-corrosion and extending the service life.

2. The coating of galvanized materials is composed of zinc, aluminum and other alloy elements, and has higher corrosion resistance and heat resistance. In contrast, galvanized materials are more prone to rust and other problems.

2. The difference in corrosion resistance

1. The corrosion resistance of galvanized materials is relatively weak, especially in humid environments, it is easy to rust, so it is suitable for indoor construction, decoration, furniture and other occasions.

2. Aluminum-zinc-plated materials have higher corrosion resistance, not only suitable for indoor environments, but also can be used as anti-corrosion materials in outdoor construction, automobiles, ships, chemicals and other fields.

3. The difference in heat resistance

1. The coating of galvanized materials can maintain good anti-corrosion effects for a long time in an environment below 200°C, but when the temperature exceeds 200°C, the zinc coating will oxidize and fall off.

2. The coating of galvanized materials can withstand higher temperatures and generally maintain good anti-corrosion effects in environments up to 315°C.

IV. Cost differences

1. The manufacturing process of galvanized materials is simple and the cost is low, which is suitable for anti-corrosion needs in general occasions.

2. The manufacturing process of galvanized materials is complex and the cost is high, which is suitable for anti-corrosion materials under high requirements.

[Conclusion]

The difference between galvanized materials and galvanized materials mainly lies in the composition of the coating, anti-corrosion performance, heat resistance and cost. Therefore, when selecting materials, it is necessary to determine according to specific needs. If only general anti-corrosion needs are required, galvanizing can meet the needs; if higher anti-corrosion and heat resistance are required, galvanized materials can be selected.
