The difference between copper tube and brass tube

The difference between Copper Tube and Brass Tube

Brass and copper differences:

1, the first component content is not the same, Copper Pipe is mainly composed of copper (Cu), the content of more than 99.5%, almost no other elements added. Brass pipe is an alloy of copper (Cu) and zinc (Zn), generally containing a higher proportion of zinc, such as ordinary 65 copper is containing 65% copper and 35% zinc.

2. Secondly, the color of the copper tube is deep red or purple, and the brass tube is yellow, which is caused by the different zinc content.

3. Physical properties: Copper tube has excellent thermal conductivity, electrical conductivity and plasticity, still maintains good strength at high temperatures, copper tube is closer to pure copper material, suitable for high temperature conditions; For example, the accessories of air conditioning are basically made of copper, and brass pipes are similar to copper in terms of thermal conductivity, electrical conductivity and plasticity, but compared to pure copper, brass has higher strength and hardness.

4. Corrosion resistance: The corrosion of copper pipes to some chemical media is strong, and corresponding anti-corrosion measures need to be taken. The brass pipe contains zinc components and has good corrosion resistance, especially for the corrosion of seawater and some chemical substances.

5. Application: Copper tubes are often used to make wires, electrical components, Musical Instruments, etc., as well as heat exchangers and cooling equipment under high temperature conditions. Brass pipe because of its better corrosion resistance and mechanical properties, widely used in bathroom products, water pipes, decoration of some particularly large decorative pipes.
