Brass Grade HT 1/2 is a high-tensile copper–zinc alloy developed for applications requiring higher strength and hardness than standard brass while maintaining good corrosion resistance and machinability. This grade is engineered to perform reliably under mechanical stress and in demanding service conditions.
Brass Grade HT 1/2 offers excellent machinability, good wear resistance, and stable mechanical properties, making it suitable for precision and heavy-duty components. It is commonly used in high-strength plumbing fittings, valves, pump parts, marine hardware, fasteners, and general engineering components where durability, dimensional stability, and long service life are critical for safe and efficient operation.
