Hot deformation behavior and cold workability of Cu-12Mn-13Zn-1Sn-1Al-0.1Si-0.1Ce alloy with white chromaticity

► An alloy proposed with white chroma and good anti-tarnishing capability in salt spray. ► The constitutive relationship obtained as ɛ′ = e22.22 sinh4.445 (0.00844σ)e−205.06/RT. ► As ɛ = 0.7, two unsafe zones got in processing map, 600-650 °C and 780-800 °C at 0.56-10 s−1. ► Wide range of annealing parameters and good cold workability obtained.
