Most research on single-point incremental forming (SPIF) has focused on aluminum sheets of various thicknesses and titanium and steel with moderate mechanical resistance and low thicknesses.However, brass alloys, which exhibit moderate resistance comparable to certain aluminum alloys, have yet to receive much attention from researchers.Consequently, the formability of brass alloys requires a more thorough investigation.This study examines two ductile materials: Aluminum 1100 and Brass CuZn37.Both materials were formed under identical conditions into a hyperbolic truncated pyramid with varying wall angles ranging from 20° to 80° using the SPIF process, with 1073spx dimensions of 150 mm × 150 mm and a thickness of 0.

8 mm.A comparison was made based on fracture depth, maximum wall angle, and minimum thickness before fracture to evaluate the formability of brass alloys in relation to aluminum alloys.The results indicate that while Aluminum 1100 exhibits higher formability than Brass CuZn37, the differences in formability between the two materials are relatively small.The fracture depth, maximum wall angle, and minimum thickness before fracture were 37.1 mm, 80.

21°, and 0.24 mm for Aluminum 1100, compared to 34.4 mm, 76.81°, and 0.33 mm for Brass CuZn37.

Notably, the effect of 100w products process parameters on the formability of Brass CuZn37 was significantly greater than their effect on Aluminum 1100.
