FAQ

We support custom copper in different sizes, designs and finishes.

Yes, we can provide samples for free, but need buyer to provide shipping cost. Also can provide customized samples according to your drawing , sample charge can be refunded when bulk order released

(Outer diameter - Wall thickness) * Wall thickness * 0.028 * Length (m) = Weight (kg)

Weight (g) = π * d² / 4 * l * 8.4 (where d is the diameter (mm) and l is the length (m) )

Tin is an excellent soldering material, which enhances welding performance. Additionally, tin plating on copper busbars improves their electrical conductivity, heat dissipation, and corrosion resistance.

Copper fittings and brass fittings differ in material composition, properties, and applications. Copper fittings are made from pure copper, offering exceptional electrical and thermal conductivity, making them the preferred choice in fields requiring specific material properties, such as water lines, medical applications, gas transmission, and heat exchangers. On the other hand, brass fittings are made from a copper alloy containing zinc, which not only retains the excellent characteristics of copper but also significantly enhances strength and hardness due to the addition of zinc. This makes brass fittings highly adaptable and durable, and they are widely used in plumbing systems, automotive manufacturing, and various mechanical equipment.

Continuous cast brass rods and extruded brass rods differ in production processes and properties. The former is produced through liquid cooling and solidification, resulting in high strength and good electrical conductivity, making it suitable for electrical components. The latter is obtained through the extrusion process, offering excellent plasticity and workability, and is commonly used in precision machining applications. Each has its own advantages in terms of cost and application.

Our pricing consists of the copper price plus processing fees. The copper price is determined by the current market rates, while the processing fees may vary depending on the specific requirements of the customer.

Yes, we can provide recycled copper products, and we are certified with the SCS certificate.

Here are copper end feed fittings, copper press fittings, solder ring fittings, ACR copper fittings, brass compression fittings, brass solder fittings, brass thread fittings and PEX fittings. These fittings are mainly used in the plumbing, gas and ACR industry. According to the shape and functions, the copper fittings generally includes Copper Elbows, Copper Tee, Copper Coupling, Copper coupling reducer, Copper adapter, Copper Union, copper trap fittings, copper end caps, crimp ring, Copper full cross over, Copper partial cross over, U bends and etc.

Copper end feed fittings are commonly used copper ftting, which are made from copper and require a soldered joint to connect pipes together. The pipes-to-be-joined are inserted into the ftting, which is heated. Solder flls the small gap between pipe and ftting, sealing and making a strong joint which is resistant to pulling and rotation of the pipes. This type of ftting requires that solder wire must be melted and fed into the joint as it is heated. Copper end feed fttings are slim and neat, inexpensive, and form a strong joint between pipes. They are probably the most reliable too for use in walls, under floors and other inaccessible locations as the joint is more secure and less likely that pipes will separate or O-rings deteriorate, resulting in leaks. However, they are more difficult to use, and since the ftting must be heated  using a blowtorch, there is always the danger of fire. Also, preparation of pipes and ftting is essential, and these must be cleaned with wire wool so that solder flows and coats all the surfaces being joined.
