What do I need to pay attention to when applying copper in the construction industry?

When applying purple copper in the construction industry, you need to pay attention to the following issues:

Corrosion resistance:

Purple copper has good corrosion resistance in general environments, but may corrode in specific environments, such as high humidity or environments containing certain chemicals.

Countermeasure: Appropriate surface treatment, such as applying a protective coating or using a copper alloy with greater corrosion resistance.

Mechanical Strength:

The relatively low hardness and strength of purple copper makes it unsuitable for high loads or shock loads.

Response: Use reinforced copper alloys where high-strength components are required, or increase the strength of copper violet by cold working.

Joining and soldering:

Purple copper has good solderability, but requires the use of appropriate soldering techniques and solder.

Countermeasures: Choose appropriate solder and soldering techniques, such as tin or copper solder, and ensure good solder quality.

Coefficient of thermal expansion:

Copper has a high coefficient of thermal expansion and the effect of temperature changes on the structure needs to be considered.

Countermeasures: Allow appropriate expansion gaps in the design or use materials with low coefficients of thermal expansion.

Surface treatment:

Purple copper is easy to oxidize in the air to form copper green, which affects the aesthetics.

Countermeasures: Perform surface treatment, such as painting, anodizing or using anti-corrosion coatings.

Cost:

The cost of purple copper is relatively high, need to find a balance between cost and performance.

Response: Choose materials wisely, optimize the design to reduce the amount of material used, or find more cost-effective alternatives.

Machinability:

Copper has good machinability, but lubrication and cooling need to be paid attention to during machining to prevent the material from overheating.

Countermeasures: Select appropriate machining processes and lubrication and cooling fluids to ensure machining quality.

Fire performance:

Purple copper has a high melting point and good fire resistance, but attention needs to be paid to compatibility with other materials.

Countermeasures: Consider fire protection requirements during design to ensure compatibility with other materials.

Recycling:

Purple copper has good recycling value, but attention needs to be paid to the recycling of the material during use.

Countermeasure: Promote recycling of purple copper materials to reduce waste.

Environmental impact:

During mining, smelting and processing, copper materials may have an impact on the environment.

Countermeasures: Adopt environmentally friendly production processes to reduce the impact on the environment.

In conclusion, when applying copper in the construction industry, it is necessary to consider the performance, cost, processability, environmental impact and other factors of the material, and take appropriate measures to ensure the reasonable use and long-term performance of copper materials.
