Brass Tube
Material Highlight Brass tube is a seamless metal tube made of copper-zinc alloy. It features high strength, corrosion resistance, excellent thermal conductivity, and high low-temperature strength. It is available in soft-tempered and hard-tempered conditions, with a melting point of 1356.15 K (1083 °C), tensile strength ≥ 290 MPa, elongation ≥ 35%, and surface roughness Ra ≤ 1.6 μm. It can be processed by cutting, bending, flaring, and other processes. For premium quality sourcing, visit brass tube solutions.
Ⅰ. Characteristics of Brass Tube
⚙️ Excellent Corrosion Resistance
Brass tube exhibits outstanding corrosion resistance and can withstand the erosion of water, air, acids, alkalis, and various other media, making it widely used in many industrial fields.
🔥 Excellent Thermal Conductivity
With high thermal conductivity, brass tube can transfer heat efficiently and is widely used in heating, gas supply, and other related fields.
⚡ Excellent Electrical Conductivity
Due to the good electrical conductivity of brass itself, brass tube is extensively applied in the electrical industry, such as for wires and conductors.
🌀 Good Plasticity
Brass tube can be formed through heating and cooling processes, enabling the production of pipes in various shapes and specifications to meet different application requirements.
🔒 Good Sealability
The connection parts of brass tubes adopt threaded or welded connections, achieving reliable sealing and preventing leakage of liquids or gases.

Ⅲ. Classification of Brass
🔹 Special brass refers to alloys composed of two or more alloying elements, such as lead, tin, manganese, nickel, iron, and silicon. Brass has strong wear resistance. Special brass is also known as high-strength brass, featuring high strength, high hardness, and strong chemical corrosion resistance, as well as excellent machinability.
Seamless brass tubes drawn from brass are soft and highly wear-resistant. Brass seamless tubes can be used in heat exchangers, condensers, low-temperature pipelines, and submarine transportation pipelines, as well as for manufacturing sheets, strips, bars, tubes, and cast parts.
With a copper content of 62%–68%, it has high plasticity and is suitable for fabricating pressure-resistant equipment.
According to the types of alloying elements contained, brass is classified into ordinary brass and special brass. Brass used for plastic forming is called wrought brass.
✨ High strength & plasticity combination make brass tubes ideal for precision engineering.
Ⅳ. Applications
Common types of brass tubes include electrical tubes, refrigeration tubes, high-pressure resistant tubes, corrosion-resistant tubes, connection tubes, water supply tubes, electric heating tubes, and industrial tubes.
