Frequently asked questions

What is H62 Brass (CuZn37)?

H62 Brass (CuZn37) — Copper. General-purpose brass bar and plate

What is the maximum service temperature of H62?

Typically about 150 °C; the practical limit depends on media, stress and design life — acceptance per the governing standard.

What is the tensile strength of H62?

The specified minimum tensile strength is 345 MPa for the main product form. Minima for other forms and sizes are listed under "Mechanical minima by form" on this page.

Which standards cover H62?

ASTM B134/B134M, ASTM B36/B36M, EN 12163 (copper alloy rod), EN 12167 (copper alloy profiles and bars), EN 12449 (seamless copper tubes), EN 1652 (copper plate, sheet and strip)

Where is H62 typically used?

Aquaculture & harbour works (Marine & Offshore)

In which forms is H62 available?

Tube, plate, strip, bar, forgings, wire and other forms — sizes and delivery condition confirmed per order, with EN 10204 3.1 / 3.2 certification.
