The differences between Brass Fitting and Plastic Fitting are as follows:
Material difference
Brass Fitting is mainly made of copper alloys, while Plastic Fitting is made of various plastic materials. Copper alloys have excellent corrosion resistance and high thermal conductivity, while plastics are light and easy to process.
Corrosion resistance
Because copper alloy has good corrosion resistance. This is why Brass Fitting is suitable for use in contact with media such as water and steam. Plastic Fitting, by contrast, is less resistant to corrosion. Aging or deformation may occur, especially when exposed to chemicals or high temperature vapors.
Thermal conductivity
Copper alloys have excellent thermal conductivity. Therefore, Brass Fitting is suitable for applications where high temperature fluids need to be transferred, such as heat sinks, heat conductors, etc. In contrast, plastics have poor thermal conductivity. Therefore, the application of Plastic Fitting in these situations may be limited.
Mechanical strength
Copper alloys have high mechanical strength. In particular, it performs better under pressure and tension. For this reason, Brass Fitting is suitable for applications that are subject to high pressure and impact, such as pipe connections. In contrast, the mechanical strength of plastics is relatively low. Therefore, the application of Plastic Fitting in these occasions may have certain limitations.
Cost and maintenance
Due to the relatively high price of copper alloys. Therefore, the cost of Brass Fitting is correspondingly high. At the same time, because the installation and maintenance of copper pipes requires professionals and special tools, its maintenance costs are also high. In contrast, Plastic Fitting is less costly and easy to install and maintain. However, it is necessary to pay attention to the temperature and pressure limits of its use.
Application field
Due to the excellent properties of copper alloys, Brass Fitting is widely used in construction, industry and medical fields. The plastic pipe fittings are light and easy to process because of their characteristics. It is also widely used in the fields of construction, decoration and medical equipment.
To sum up
The application difference between Brass Fitting and Plastic Fitting mainly lies in the aspects of material, corrosion resistance, thermal conductivity, mechanical strength, cost, maintenance and application fields. When selecting suitable pipe fitting materials, comprehensive consideration should be made according to actual application scenarios and specific requirements.
