H5 is a new Cu-Zn-Al-Ni based Cu-based high strength elastic alloy. Its strength exceeds tin phosphor bronze and some beryllium bronze. The alloy has good hot and cold processing properties, can produce a variety of types of plates, strips, rods, wire and pipe. Can be a variety of welding. The melting temperature of the alloy is 1473-1623 K, the thermal processing temperature is 1023-1073 K, the total processing rate is more than 90%, the annealing temperature is 923-973 K and the cold working rate is more than 40%. When the cold working rate is 35%, the sheet properties σ_b≥715 MPa, HV≥2156 MPa, σ≥3%, the wire properties σ_b≥882 MPa, HV≥2205 MPa, E≥120540 MPa, ρ = 10.33 × 10 ~ (4) ) Ω (?) M, salt corrosion rate of 0.0013 mm / year. All the properties except delta are superior to tin-phosphor bronze QSn 6.5-0.1 alloy and the cost is lower than that of QSn6.5-0.1 alloy.
