Selecting the right material is crucial for successful cold roll forming operations. This comprehensive guide compares the formability, strength characteristics, and cost considerations of various materials including mild steel, galvanized steel, aluminum alloys, stainless steel, and high-strength low-alloy (HSLA) steels.
Technical specifications highlight material thickness ranges (typically 0.3mm to 4.0mm), yield strengths (from 235 MPa up to 1180 MPa in automotive AHSS), and springback characteristics that tooling designers must compensate for when developing roll pass progressions and overbend stations.
