H63 (T27300) Brass Tube

H63 (T27300) Brass Tube is a high-performance brass alloy tube with a copper content of 63% and a zinc content of 37%. Its excellent mechanical properties and machinability make it an ideal choice for customers with high material quality requirements. Compared to other brass alloys, H63 brass tube has a moderate copper content and fewer impurities than H62, resulting in higher strength and hardness, capable of withstanding large mechanical loads. It also exhibits good plasticity at hot, meeting the needs of complex shape processing.

H63 brass tube's high strength and hardness make it suitable for manufacturing structural components requiring high load-bearing capacity. It is widely used in pins, rivets, springs, nuts, valves, and tube fittings. Its high hardness ensures these components maintain high stability and reliability during long-term use, making it suitable for high-load, high-pressure working environments.

In addition to high strength and hardness, the good plasticity of H63 brass tube during hot working is also one of its important characteristics. Despite its inherent hardness, H63 brass tubing retains good plasticity when hot, allowing for hot extrusion and bending to meet the manufacturing demands of complex shapes and precision requirements. Its excellent machinability also includes good machinability and weldability, enabling efficient and precise processing during production, reducing costs and increasing efficiency.

The low impurity content of H63 brass tubing contributes to its stable mechanical properties, strong corrosion resistance, and wear resistance, making it suitable for applications with harsh working conditions and ensuring high efficiency and reliability over long-term use.

Industry knowledge

Copper tubes are the "blood vessels" of the refrigeration system, mainly used in condensers, evaporators and connecting pipelines. Its high thermal conductivity (with a thermal conductivity coefficient of approximately 400 W/m·K) enables rapid heat transfer, enhancing the energy efficiency ratio of air conditioners and refrigerators. The promotion of environmentally friendly refrigerants such as R410A has further driven the development of copper tubes towards high pressure resistance, thin-walled and lightweight. Industry standards such as ASTM B280 (Copper Tubes for Air Conditioning) have strict regulations on indicators such as cleanliness and tensile strength to avoid refrigerant leakage and system blockage.
