Short answer: Formability is how far a metal can be stamped, drawn or bent without cracking; it is governed by strain hardening (n-value), plastic anisotropy (r-value), ductility and temper, so the right alloy and temper decide whether a part draws cleanly or splits at the corner.

What Drives Formability
The strain-hardening exponent (n) spreads strain and resists local thinning; the normal anisotropy (r) resists earing and splitting in deep drawing. These sit with ductility and Yield Strength Vs Tensile Strength, and are set by Cold Rolling Vs Hot Rolling e Aluminum Temper Designations.

Forming Processes
Stamping and drawing use high-r low-carbon steel and 3003-O aluminium; bending and roll-forming use Metal Stamping Supplier, Aluminum Extrusion Supplier e Metal Bending Guide; forging and casting cover the thick and complex shapes via Forging Supplier e Casting Supplier. Avoid over-forming brittle alloys — see Metal Brittle Fracture Guide.
Quality & Tolerances
Verify with Mill Test Certificate Guide, surface finish per Surface Roughness Ra Guide e Metal Tolerances Fits Guide, and confirm soundness with Metal Ndt Guide. Good lubrication and tool condition are as important as the metal itself.

A metal’s ability to be stamped, drawn, bent or stretched into shape without cracking or excessive springback — set by ductility, n-value and r-value.
Low-carbon steel and soft aluminium (e.g. 3003-O) and copper strip draw and bend very well; work-hardened tempers and high-strength steels need more care.
n-value (strain-hardening exponent) measures how strain spreads; r-value (plastic anisotropy) measures resistance to thinning in drawing — both raise formability.
Its high strength and work hardening give noticeable elastic recovery after forming, so tooling must over-bend or coin to hold the shape.
